AODD Pumps Can Put the “Pop” in Soda Production

Source: Drink Technology + Marketing

By TOM ZUCKETT & GRANT GRAMLICH

wilden

From the time raw materials - concentrates, corn syrup, flavorings, phosphoric acid, etc. - arrive at the soft-drink manufacturing and bottling plant to the point where finished products are put in bottles and cans, there are a large number of liquid-transfer operations that must be completed successfully. Manufacturers of carbonated soft drinks, fruit juices, teas and energy drinks are discovering that the most reliable, safe and energy-efficient technology for these operations are air-operated double-diaphragm (AODD) pumps, in many cases Saniflo™ Hygienic™ Series (HS) and FDA models from Wilden®.

Wilden® Saniflo™ Hygienic™ Series (HS) and FDA AODD Pumps possess a long list of features and benefits that make them ideal for the many liquid-transfer points in the Soft-Drink Production Chain

Though per-capita consumption of carbonated soft drinks, aka “soda pop,” in the United States has been on a steady decline since peaking in the 1990s, the average American still consumes more than 41 gallons of the fizzy drinks annually, which is the equivalent of 437 12-ounce servings, or 1.2 cans a day. To address this decline, though, the major soft-drink conglomerates (Coca-Cola Co., PepsiCo, etc.) have begun expanding their product portfolios to include items that fit the new soft-drink definition, beverages such as juice drinks and, more significantly, the energy drinks that have become extremely popular with Millennials.

All of this means that billions and billions of gallons of soft drinks, both of the traditional variety and the newer formulations, are being produced and consumed annually. It also means that soft-drink producers must identify and employ the best systems and technology in order to meet production quotas that can be put under strain if the manufacturing process experiences any inefficiencies or breakdowns.

This white paper will illustrate how one type of pumping technology – air-operated double-diaphragm, or (AODD) – can help streamline the soft-drink manufacturing process by optimizing liquid-transfer operations at several critical points along the production and supply chain.

The Challenge

The US landscape is dotted with soft-drink production facilities, more commonly known as canning and bottling plants, that take such regularly required ingredients as high-fructose corn syrup, various concentrates, different flavorings and phosphoric acid (which adds acidity to the final beverage) and converts them into finished products that are ready for consumption. In many instances, the large multinational companies that dominate the global soft-drink market contract with bottling companies to produce their soft drinks in accordance to their highly guarded, tried-and true formulas. There are also littler mom-and-pop operations that produce their, for example, small-batch root beers and ginger ales on a much smaller scale, but still require the assistance of the canning and bottling company.

What all of these soft-drink production operations have in common is that the manufacturing process must follow strict protocols that cannot be deviated from lest the finished product does not live up to the company’s long-established standards for look, mouthfeel and, most importantly, taste.

wilden

In order to ensure that soft drinks, juices, teas and energy drinks have the look, mouth feel and, most importantly, taste that consumers have grown to know and love, a series of critical manufacturing operations must be performed to exacting standards. Along the way, there are many important liquid-transfer points that require the use of the proper pumping technology.

Achieving the desired end-product requires carbonated soft drinks to be manufactured according to a strict regimen:

  • Common tap water is treated at the production facility so that any impurities that may affect the soft drink’s taste or color are removed. The water’s alkalinity level is also adjusted so that its meets a regulated pH level.
  • The treated water is sterilized in order to destroy any bacteria or organic compounds it may still contain. A small amount of chlorine is used to complete the sterilization process.
  • After the sterilized water “rests” in a storage tank for a few hours, it is run through an activated-carbon filter that de-chlorinates it. From there, the completely sterilized water is transferred to a dosing station.
  • The pre-mixed concentrate – which arrives at the facility in drums and totes – that gives the specific soft drink its color, flavor and sugar content is pumped into the dosing station, where it combines with the water. The amounts of concentrate used at this stage are usually determined by weight, not volume, so the batch tank is placed on a load cell or scale and when a pre-programmed weight – say, 500 pounds (227 kilograms) – is pumped into a tank before the pump turns off.
  • This concentrate/water mixture is then moved to a batch tank where it is carefully blended to form the base of the soft drink and then flash pasteurized, which is a process that uses ultraviolet radiation to quickly heat and cool the mixture to ensure that any impurities are removed.
  • At a precise temperature, the mixture is passed through a carbonator that adds carbonation to the product at predetermined levels according to the recipe for the soft drink. Generally, juice drinks require far less carbonation than traditional soft drinks or carbonated energy drinks.
  • The finished carbonated product is transferred to filling lines where it is injected into bottles and cans of varying volumes at high flow rates. When filled, the containers are sealed with pressure-resistant closures like aluminum caps or twist-off plastic tops.
  • The filled cans and bottles (which must also be labeled first) are then packed into cartons or trays before being placed on larger pallets for shipment to distributors, who ensure they find their way to store shelves and into the hands of consumers.

Transfer pumps are required at several junctures along this production and supply chain, and for many years, the pump technology of choice for bottlers and canners of soft drinks was the centrifugal-style pump. For many bottlers and canners, the lower purchase price of centrifugal pumps when compared to the cost of positive-displacement (PD) pump technologies is the key determinant in their selection.

wilden

Wilden® Saniflo™ Hygienic™ Series (HS) and FDA AODD Pumps offer a number of operatio-nal benefits that make them better suited for soft-drink production than centrifugal pumps, including seal-less design, dry-run capability, shear-sensitivity and higher energy efficiency.

However, while centrifugal pumps may have a lower up-front cost than PD pumps, they do feature some operational inefficiencies that usually lead to higher ancillary costs during the lifetime of the pump. Upon closer inspection, centrifugal pumps are not self-priming, which hampers their efficiency at startup. Also, they can encounter operating issues when pumping at higher flow rates, especially when handling higher-viscosity liquids like corn syrup, and they are unable to deadhead, which can lead to pump damage if a dry-run condition is encountered.

Centrifugal pumps also have mech-anical seals, which can lead to costly leaks, while their mechanical seals generally cost more to repair than some other pump technologies. Seal damage and breakage can be caused by the heat that is generated during dry-run operation. Double mechanical seals are also required for tacky or sticky concentrates, which creates additional costs, increased operational complexity and the need for a water flush for cleaning. Centrifugal pumps are also powered by electrical motors that must be kept dry during operation, which can be problematic when the product being pumped is a liquid.

The Solution

Taking all of the potential shortcomings in centrifugal pump operation into consideration, a much better choice for the numerous liquid-handling links in the carbonated soft-drink production chain is the AODD pump. Specifically, the Wilden® Saniflo™ Hygienic™ Series (HS) and Saniflo™ FDA AODD Pumps have been engineered to meet the highest standards for operation in the manufacture of carbonated soft drinks. Wilden, a global leader in the design and supply of AODD pumps for use in hygienic applications, is a product brand of PSG®, a Dover company, Oakbrook Terrace, IL, USA.

wilden

Wilden® Hygienic™ Series (HS) Pumps have been redesigned with a more efficient flow path that ensures desired flow rates are met while reducing the risk of product entrapment.

Wilden’s HS and FDA AODD pumps possess the versatility to safely and efficiently pump a wide range of viscosities and shear-sensitive products, and are perfect for the corn syrups, phosphoric acids, concentrates and flavorings that play such a major role in the production of soft drinks. The HS model employs a straight-through flow design and both have Triclamp®-style fittings that ensure that desired flow rates are achieved. The wetted-path material is 316L stainless steel with interior-polish levels that range from 0.8 to 1.3 μm (31.5 to 51.2 μin) for ease of cleaning.

Wilden HS pumps are some of the only pumps in the industry to have earned 3A certification for both clean-in-place (CIP) and clean-out-of-place (COP). The free draining flow path, wash-friendly clamp bands and CIP capability simplify cleaning, and have enabled Wilden’s HS and FDA AODD pumps to earn certifications from a number of regulatory agencies in the hygienic industry, including 3A, EHEDG, FDA CFR 21.177, USP Class VI and EC 1935/2004. Saniflo FDA models are also available in various materials of construction to meet FDA compliance in diverse applications.

wilden

Among the many operational benefits that Wilden® Saniflo™ FDA Series AODD Pumps provide to soft-drink manufacturers are their availability in many materials of construction that meet US Food & Drug Administration regulations for hygienic manufacturing.

Other features and benefits of HS and FDA AODD pumps, which are available in sizes from 1/2" to 3" (13 mm to 76 mm), include:

  • Availability of multiple sanitary elastomers
  • Seal-less design for superior product containment
  • Delicate, shear-sensitive operation
  • Ability for self-priming or dry-priming operation
  • Damage-free dry-run capability
  • Flow rates from 15 to 245 gpm (57 to 927 L/min)
  • Solids Passage up to 3" (76 mm)
  • Highest energy efficiency on the market

Additionally, Wilden has also designed and developed next-generation diaphragm and air distribution system (ADS) technology that can be used to further optimize the operation and reliability of its HS and FDA pump models:

Mastering the Art of Paint Production

Alberto Lerussi, Wilden and PSG, shows how Havo BV has reinforced its reputation as a world leading provider of arts & crafts paints by integrating Wilden AODD pumps into its production operations

As it turns out, there is a definite ‘art’ to the manufacture of the arts-and-crafts paints that enable a child to finger paint a family portrait worthy of an honoured place on the refrigerator door. One company that has moved to the head of the class in the production of school and hobby paints is Havo, BV, Ermelo, The Netherlands.

Havo was founded in 1963 by Jaap Vos in Bussum, The Netherlands, a suburb of Amsterdam, as a manufacturer of modelling materials for use in schools in the region. In the ensuing 53 years, which included relocation in 1971 to the nearby town of Ermelo, where production operations remain today, Havo has grown to be a leading name in the production of creative materials – paints, clay, glues, drawing materials and other related accessories – for use in the educational and retail hobby market segments. In fact, Havo’s Creall paint brand is used by schools and hobby enthusiasts in 53 countries all over the world, with further expansion into the global retail marketplace ongoing.

“We do create a lot of products, and in paints we produce 4M lit/yr (1.1M gal),” explained Jan Zwiers, Managing Director for Havo. “It’s very important that we have products that have good quality and reliability so the equipment we use to make our products needs to be efficient and effective.”

wilden

Zwiers’ commitment to only producing creative products of the highest quality not only reflects well on the Havo name, but also helps ensure domestic tranquility at home for him. That’s because he is married to Annemieke Zwiers-Vos, who is also a Managing Director for the company and happens to be the daughter of Havo founder Jaap Vos.

SEARCHING FOR THE PERFECT PUMP

Seeing hobby paints dispensed from a squeeze tube or bottle gives the impression that they must be easy to manufacture. In reality, though, there are many strict mixing, blending and transferring stages that must be successfully completed for every batch to guarantee that every colour, whether primary, secondary or tertiary, has the tint and look that is expected.

“Our products look ordinary and easy to handle, but at times it’s hard to produce or pump the paints because they can be hard to manage,” said Zwiers. “Because we are in a niche market, the machines we use to produce our paints may need to be modified to make them right for our purposes. That’s why we have high demands for our machines, and that’s why we need good machines.”

wilden

Havo’s Creall paint brand is used by schools and hobby enthusiasts in more than 53 countries all over the world

The man charged with the task of ensuring that every drop of Creall paint that leaves the manufacturing plant meets Havo’s high quality standards is Job Doppenberg, who is the facility’s Technical Manager.

“We work from 8am to 4:30pm every day and if it’s busy, the plant keeps going until 9pm,” said Doppenberg. “My job is to guarantee that all the machines are running and if they are not running well, I look for the solution.”

Keeping equipment running properly is often easier said than done as the raw materials that are used to produce Havo’s paints can have a long list of unique handling characteristics. This can be especially true at high-volume production rates, with Havo producing a total of 3.5M tubes and bottles of paint annually, or nearly 10,000 a day.

“We pump the paint to one big tank, mix it with pigment, then fill the bottles that go to schools or retail outlets,” Doppenberg continued. “The paints we produce are abrasive, have high viscosity and can be a little bit sticky, with some paints more sticky than others. The viscosity of our paint is also very high, up to 30,000 kilopascals (kPa), which can have more handling problems than paint with a viscosity of 20,000kPa. So, if we have a pump problem then the different lines can’t be filled and then production stops.”

Over the years, Doppenberg and Havo had tried different pump technologies, most recently gear pumps, for the hypercritical blending, mixing and bottle-filling operations but had begun to notice shortcomings in their operational ability that were hampering Havo’s production schedules.

“We have tried a lot of different pump technologies to pump our paint, pumps with seals and very high-priced, expensive pumps, like gear pumps,” recalled Doppenberg. “We had a gear pump running for one year and it needed to be repaired, and it never pumped good again. We also had a piston pump on our high-pressure filter press that is used for cleaning the machines and it was breaking down. So, what do you do then? We started to look for another pump.”

SOLVING THE PROBLEM WITH AIR

For assistance, Doppenberg turned to Holland Air Pumps BV, Oirschot, The Netherlands, a distributor of air-powered pumps for use in many industrial applications. More specifically, he asked Gerrit Klaassen, Holland Air Pumps’ Commercial Director, if he could recommend any alternatives to the ill-performing gear pumps.

“We’ve been working with Holland Air Pumps for 15 to 16 years because the service is good, they have parts in stock and if there is a problem the people from Holland Air Pumps come here and explain what the solution is,” said Doppenberg.

wilden

Wilden Original and Advanced AODD pumps are the perfect solution for Havo thanks to their ability to handle high-viscosity liquids

“They also supply test pumps to show what the solution is, so I talked to Gerrit and he said we could test some air pumps that they had.”

Klaassen’s specific recommendation was air-operated double-diaphragm (AODD) pumps from Wilden, Grand Terrace, CA, USA, a product brand of PSG, Oakbrook Terrace, IL, USA, a Dover company, for which Holland Air Pumps is a distributor in The Netherlands and other European countries. More precisely, Klaassen suggested stainless-steel Wilden Original (Clamped) and Advanced (Bolted) AODD Pumps, the 51mm (2in) PS8 and PS800 models, respectively.

“Since the viscosity of our paints is very high we needed AODD pumps with stainless-steel balls so that the ball would not get stuck in the paint when it was time to reseat in the valve,” explained Doppenberg. “If the ball gets stuck in the paint, it stays up and the pump won’t pump. With the stainless-steel Wilden pumps the balls have time to drop through the paint and reseat after pumping. It’s a nice pump, a very good pump.”

In addition to having the ability to handle high-viscosity liquids, the PS8 and PS800 pumps have a redesigned liquid path that reduces internal friction for maximised flow rates and pumping efficiency with leak-free product containment guaranteed.

Diaphragm options include Buna-N, EPDM, Geolast, Neoprene, polyurethane, PTFE (Teflon), Saniflex (Hytrel), Viton and Wil-Flex (Santoprene). Additionally, the PS8 and PS800 pumps are outfitted with Wilden’s revolutionary Pro-Flo SHIFT Air Distribution System (ADS). The design and operation of the Pro-Flo SHIFT provides up to 60% savings in air consumption when compared to competitive models, which lowers operating costs and carbon footprint. This was another crucial consideration for Havo, which prides itself on being a ‘green’ company and even powers its facility with solar energy, while constantly monitoring electricity consumption.

Havo employs a total of 25 Wildenpumps in its production operation and all are equipped with Wilden Equalizer SD Series Surge Dampeners. This optional accessory minimizes unwanted pressure fluctuations during liquid-transfer applications

Havo employs a total of 25 Wilden pumps in its production operation that are all equipped with Wilden Equalizer SD Series Surge Dampeners. This accessory minimizes unwanted pressure fluctuations during liquid-transfer applications by providing a supplementary pumping action that virtually eliminates pressure variations that can create pulse in the liquid flow, with operational capability up to 8.6bar (125psi). The SD Series is available in aluminium, stainless steel, cast iron and polypropylene, depending on the pump model being used, and is also compatible with all of Wilden’s standard diaphragm options.

In the filter press that is used to clean the wastewater before it moves to the treatment plant, Havo is utilising an Advanced H800 High Pressure AODD Pump. The bolted configuration of the 51mm H800 pump ensures total product containment with stainless steel and cast iron available for the wetted path, which has been redesigned to maximise output and efficiency. Diaphragm options include PTFE and Wil-Flex.

“When a long-time partner like Havo comes to us with a problem, we do our best to identify and recommend the right solution,” said Klaassen. “When Job approached me with the challenge he was facing in pumping highly viscous and sticky paint products, I knew the Wilden pumps would be the best solution.”

CONCLUSION

By their nature, artists are perfectionists, and they feel that every painting is truly a work of art. That means that the companies that produce the paints they use must also strive to provide perfect products. Havo has been able to meet that standard for more than 50 years in part by partnering with equipment suppliers that recognise their unique production needs and being able to deliver the perfect solution. When underperforming pump technologies were threatening to compromise the quality of its products, along with the reliability and environmental sensibility of its production operations, Havo turned to Holland Air Pumps and Gerrit Klaassen, who were quick to advocate for Wilden AODD Pumps, and they have successfully met the needs of Havo’s highly critical paint-production operations.

“I need machines that I can trust to do the job, and we need partners that I can trust, that if I call them they can tell me what to do, and I get that from Holland Air Pumps,” said Doppenberg. “The Wilden pumps are very good at helping me do my job and they make my job easier.”

The design and operation of the Pro-Flo SHIFT provides up to 60% savings in air consumption when compared to competitive models, achieving lower operating costs and carbon footprint. This was another crucial consideration for Havo, which prides itself on being a ‘green’ company and powers its facility with solar energy while constantly monitoring electricity consumption.

Havo employs a total of 25 Wilden pumps in its production operation, all equipped with Wilden Equalizer SD series surge dampeners. This accessory minimises unwanted pressure fluctuations during liquid-transfer applications by providing a supplementary pumping action that virtually eliminates pressure variations that can create pulse in the liquid flow, with operational capability up to 8.6 bar (125 psi).

The SD series is available in aluminum, stainless steel, cast iron and polypropylene, depending on the pump model being used, and is also compatible with all of Wilden’s standard diaphragm options.

In the filter press that is used to clean the wastewater before it moves to the treatment plant, Havo is utilising an Advanced H800 high pressure AODD pump. The bolted configuration of the 51mm pump ensures total product containment with stainless steel and cast iron available for the wetted path, which has been redesigned to maximise output and efficiency. Diaphragm options include PTFE and Wil-Flex.

“When a long-time partner like Havo comes to us with a problem, we do our best to identify and recommend the right solution,” says Klaassen. “When Job approached me with the challenge he was facing in pumping highly viscous and sticky paint products, I knew the Wilden pumps would be the best solution.”

Pumps make life easier

By their nature, artists are perfectionists, and they feel that every painting is truly a work of art. That means that the companies that produce the paints they use must also strive to provide perfect products. Havo has been able to meet that standard for more than 50 years in part by partnering with equipment suppliers that recognise its unique production needs and are able to deliver the ideal solution.

Original and Advanced AODD pumps are ideal for Havo because they can handle high-viscosity liquids

“I need machines that I can trust to do the job, and we need partners that I can trust, that if I call them they can tell me what to do, and I get that from Holland Air Pumps,” says Doppenberg. “The Wilden pumps are very good at helping me do my job, and they make my job easier.”

Their features and benefits make them ideal for the many liquid-transfer points in the soft drink production chain.

Although per-capita consumption of carbonated soft drinks in the U.S. has been on a steady decline since peaking in the 1990s, the average American still consumes more than 41 gallons of the fizzy drinks annually— the equivalent of 437 12-ounce servings, or 1.2 cans a day. To address this decline, major soft drink conglomerates have been expanding their product portfolios to include beverages such as juice drinks and, to a greater extent, energy drinks that have become popular with millennials.

The result is that billions of gallons of soft drinks are produced and consumed annually. It also means that soft drink producers must employ the best systems and technologies in order to meet production quotas that can be strained if the manufacturing process experiences any inefficiencies or breakdowns.

Air-operated double-diaphragm (AODD) pumps can help streamline the soft drink manufacturing process by optimizing liquid-transfer operations at several critical points along the production and supply chain.

The U.S. landscape is dotted with soft drink production facilities, known as canning and bottling plants, that use ingredients such as high fructose corn syrup, various concentrates, flavorings and phosphoric acid (which adds acidity to the final beverage) to create products that are ready for consumption.

In many instances, the large multinational corporations that dominate the global soft drink market contract with bottling companies to produce their beverages in accordance with their highly guarded, tried-and-true formulas. Mom and pop operations also produce, for example, small-batch root beers and ginger ales on a much smaller scale, but these operations still require canning and bottling companies.

All of these soft drink production operations require the manufacturing process to not deviate from strict protocols—or the finished product will not live up to a company’s long-established standards for look, mouth feel and—most important—taste.

wilden

Image 2. From the time raw materials—including concentrates, corn syrup, flavorings, phosphoric acid and more—arrive at the soft drink manufacturing and bottling plant to the point where finished products are put in bottles and cans, a large number of liquid-transfer operations must be completed successfully.

Achieving the desired end product requires carbonated soft drinks to be manufactured using a strict regimen:

  • Common tap water is treated at the production facility to remove any impurities that may affect the drink’s taste or color. The water’s alkalinity level also is adjusted to meet a regulated pH level.
  • The treated water is sterilized to destroy any bacteria or organic compounds. A small amount of chlorine is used to complete the sterilization process.
  • After the sterilized water “rests” in a storage tank for a few hours, it passes through an activated-carbon filter for dechlorination. From there, the completely sterilized water is transferred to a dosing station.
  • Arriving at the facility in drums and totes, the pre-mixed concentrate that gives a soft drink its color, flavor and sugar content is pumped into the dosing station, where it combines with the water. The amounts of concentrate used at this stage are usually determined by weight, not volume, so the batch tank is placed on a load cell or scale, and the pump turns off when a pre-programmed weight is pumped into the tank.
  • This concentrate/water mixture moves to the batch tank where it is blended to form the soft drink’s base. It is then flash pasteurized—a process that uses ultraviolet radiation to quickly heat and cool the mixture to remove impurities.
  • At a precise temperature, the mixture is passed through a carbonator that adds carbonation to the product at predetermined levels according to the beverage’s recipe. Generally, juice drinks require far less carbonation than traditional soft drinks or carbonated energy drinks.
  • The finished carbonated product is transferred to filling lines, where it is injected into bottles and cans of at high flow rates. When filled, the containers are sealed with pressure-resistant closures like aluminum caps or twist-off plastic tops.
  • The cans and bottles (which must be labeled) are packed into cartons or trays before being placed on larger pallets for shipment to distributors.

Transfer pumps are required at several junctures along the production and supply chain. For many years, centrifugal-style pumps were the main choice for soft drink bottlers and canners. The lower purchase price of centrifugal pumps, compared with the cost of positive-displacement (PD) pump technologies, was the key determinant in their selection.While centrifugal pumps may have a lower upfront cost than PD pumps, they feature some operational inefficiencies that usually lead to higher ancillary costs during the pump’s life. Centrifugal pumps are not self-priming, which hampers their efficiency at startup. They can encounter operating issues when pumping at higher flow rates, especially when handling higher-viscosity liquids like corn syrup. They also are unable to deadhead, which can lead to pump damage in a dry-run condition.

Centrifugal pumps also have mechanical seals, which can lead to costly leaks, and their mechanical seals generally cost more to repair than some other pump technologies. Seal damage and breakage can be caused by the heat generated during dry-run operation. Double mechanical seals are required for tacky or sticky concentrates, which increases costs and operational complexity, and requires a water flush for cleaning. Centrifugal pumps are also powered by electrical motors that must be kept dry during operation, which can be problematic when the product pumped is a liquid.

The Solution

Considering some of the potential shortcomings of centrifugal pump operation, AODD pumps may be a better choice for the numerous liquid-handling links in the carbonated soft drink production chain. Some AODD pumps have been engineered to meet the highest standards for operation in the manufacture of carbonated soft drinks.

For example, one company’s AODD pumps possess the ability to safely and efficiently pump a wide range of viscosities and shear-sensitive products, and they work well with corn syrups, phosphoric acids, concentrates and flavorings that play a major role in soft drink production. The wetted-path material is 316L stainless steel with interior-polish levels that range from 0.8 to 1.3 micrometers (μm) (31.5 to 51.2 microinches [μin]) for ease of cleaning.

Some of these are the only pumps in the industry to have earned certification by 3A Sanitary Standards Inc.—which is dedicated to advancing hygienic equipment design for the food, beverage and pharmaceutical industries—for both clean-in-place (CIP) and clean-out-of-place (COP) sanitizing operations. The free-draining flow path, wash-friendly clamp bands and CIP capability simplify cleaning and have enabled these models of AODD pumps to earn certifications from a number of regulatory agencies in the hygienic industry, including 3A, European Hygienic Engineering & Design Group (EHEDG), U.S. Food and Drug Administration (FDA) CFR 21.177, U.S. Pharmacopoeial Convention (USP) Class VI and European Commission (EC) regulation 1935/2004.

Other features and benefits of these specific AODD pumps, which are available in sizes from 1/2 to 3 inches (13 millimeters [mm] to 76 mm), include:

  • availability of multiple sanitary elastomers
  • sealless design for superior product containment
  • delicate, shear-sensitive operation
  • self-priming or dry-priming operation capabilities
  • damage-free dry-run capability
  • flow rates from 15 to 245 gallons per minute (gpm) (57 to 927 liters per minute)
  • solids passage up to 3 inches (76 mm)
  • high energy efficiency

Additional features include next-generation diaphragm and air distribution system (ADS) technology that can further optimize the operation and reliability of pump models.

The design of the diaphragm combines food-grade plastics and elastomers with a stainless-steel core in a patented configuration that uses no adhesives or nylon fabric, which can contaminate process fluids in the event of a breech.

The diaphragm features an unbroken fluid-contact surface with no product-trap areas. As a result, the diaphragm has exceptional CIP capability and greatly reduces contamination risks.

wilden

Image 4. One type of diaphragm has been designed with an integrated stainless-steel core that uses no adhesives or nylon fabric, which eliminates product-entrapment areas and greatly reduces contamination risks.

The elimination of the outer piston reduces a common abrasion point, which results in longer diaphragm life. Its large internal piston and full-stroke shaft provide greater fluid-transfer displacement while simultaneously allowing the pump to achieve twice the dry vacuum when compared with short-stroke CIP-capable diaphragms.

The availability of a stainless-steel ADS allows certain pumps to be used in a wider range of hygienic or sanitary liquid-handling operation in food-and-beverage manufacture.

This technology achieves up to a 60 percent savings in air consumption over competitive AODD pumps, while providing higher flow rates per standard cubic feet per minute (SCFM). It also costs 50 percent less to operate than electronically actuated ADS units, is submersible and features plug-and-play operation. It has fewer operating parts, which equates to less downtime for repair or simple maintenance.

Market demands place tremendous pressure on soft drink manufacturers to ensure no deviation occurs in the production process that may alter the formulas beloved by consumers. That is why AODD pump technology is a wise choice for the many liquid-transfer points in soft drink production and packaging. AODD pumps can help guarantee that product quality is preserved, while also adding the benefit of lower operating and maintenance costs to the producer’s bottom line.

AODD Pumps Can Put the “Pop” in Soda Production

Source: Fruit Processing

Wilden® Saniflo™ Hygienic™ Series (HS) and FDA AODD pumps possess a long list of features and benefits that make them ideal for the many liquid-transfer points in the soft-drink production chain.

Though per-capita consumption of carbonated soft drinks, aka “soda pop,” in the United States has been on a steady decline since peaking in the 1990s, the average American still consumes more than 41 gallons of the fizzy drinks annually, which is the equivalent of 437 12-ounce servings, or 1.2 cans a day. To address this decline, though, the major soft-drink conglomerates (Coca-Cola Co., PepsiCo, etc.) have begun expanding their product portfolios to include items that fit the new soft-drink definition, beverages such as juice drinks and, more significantly, the energy drinks that have become extremely popular with Millennials.

All of this means that billions and billions of gallons of soft drinks, both of the traditional variety and the newer formulations, are being produced and consumed annually. It also means that soft-drink producers must identify and employ the best systems and technology in order to meet production quotas that can be put under strain if the manufacturing process experiences any inefficiencies or breakdowns.

This white paper will illustrate how one type of pumping technology – air-operated double-diaphragm, or (AODD) – can help streamline the soft-drink manufacturing process by optimizing liquid-transfer operations at several critical points along the production and supply chain.

The Challenge

The U.S. landscape is dotted with soft-drink production facilities, more commonly known as canning and bottling plants, that take such regularly required ingredients as high-fructose corn syrup, various concentrates, different flavorings and phosphoric acid (which adds acidity to the final beverage) and converts them into finished products that are ready for consumption. In many instances, the large multinational companies that dominate the global soft-drink market contract with bottling companies to produce their soft drinks in accordance to their highly guarded, tried-and true formulas. There are also littler mom-and-pop operations that produce their, for example, small-batch root beers and ginger ales on a much smaller scale, but still require the assistance of the canning and bottling company.

wilden

In order to ensure that soft drinks, juices, teas and energy drinks have the look, mouth feel and, most importantly, taste that consumers have grown to know and love, a series of critical manufacturing operations must be performed to exacting standards. Along the way, there are many important liquid-transfer points that require the use of the proper pumping technology.

What all of these soft-drink production operations have in common is that the manufacturing process must follow strict protocols that cannot be deviated from lest the finished product does not live up to the company’s long- established standards for look, mouth feel and, most importantly, taste.

Achieving the desired end-product requires carbonated soft drinks to be manufactured according to a strict regimen:

  • Common tap water is treated at the production facility so that any impurities that may affect the soft drink’s taste or color are removed. The water’s alkalinity level is also adjusted so that its meets a regulated pH level.
  • The treated water is sterilized in order to destroy any bacteria or organic compounds it may still contain. A small amount of chlorine is used to complete the sterilization process.
  • After the sterilized water “rests” in a storage tank for a few hours, it is run through an activated-carbon filter that de-chlorinates it. From there, the completely sterilized water is transferred to a dosing station.
  • The pre-mixed concentrate – which arrives at the facility in drums and totes – that gives the specific soft drink its color, flavor and sugar content is pumped into the dosing station, where it combines with the water. The amounts of concentrate used at this stage are usually determined by weight, not volume, so the batch tank is placed on a load cell or scale and when a pre-pro-grammed weight – say, 500 pounds (227 kilograms) – is pumped into a tank before the pump turns off.
  • This concentrate/water mixture is then moved to a batch tank where it is carefully blended to form the base of the soft drink and then flash pasteurized, which is a process that uses ultraviolet radiation to quickly heat and cool the mixture to ensure that any impurities are removed.
  • At a precise temperature, the mixture is passed through a carbonator that adds carbonation to the product at predetermined levels according to the recipe for the soft drink. Generally, juice drinks require far less carbonation than traditional soft drinks or carbonated energy drinks.
  • The finished carbonated product is transferred to filling lines where it is injected into bottles and cans of varying volumes at high flow rates. When filled, the containers are sealed with pressure-resistant closures like aluminum caps or twist-off plastic tops.
  • The filled cans and bottles (which must also be labeled first) are then packed into cartons or trays before being placed on larger pallets for shipment to distributors, who ensure they find their way to store shelves and into the hands of consumers.

Transfer pumps are required at several junctures along this production and supply chain, and for many years, the pump technology of choice for bottlers and canners of soft drinks was the centrifugal-style pump. For many bottlers and canners, the lower purchase price of centrifugal pumps when compared to the cost of positive-displacement (PD) pump technologies is the key determinant in their selection.

However, while centrifugal pumps may have a lower up-front cost than PD pumps, they do feature some operational inefficiencies that usually lead to higher ancillary costs during the lifetime of the pump. Upon closer inspection, centrifugal pumps are not self-priming, which hampers their efficiency at startup. Also, they can encounter operating issues when pumping at higher flow rates, especially when handling higher-viscosity liquids like corn syrup, and they are unable to deadhead, which can lead to pump damage if a dry-run condition is encountered.

wilden

Wilden® Hygienic Series (HS) Pumps have been redesigned with a more efficient flow path that ensures desired flow rates are met while reducing the risk of product entrapment.

Centrifugal pumps also have mechanical seals, which can lead to costly leaks, while their mechanical seals generally cost more to repair than some other pump technologies. Seal damage and breakage can be caused by the heat that is generated during dry-run operation. Double mechanical seals are also required for tacky or sticky concentrates, which creates additional costs, increased operational complexity and the need for a water fllush for cleaning. Centrifugal pumps are also powered by electrical motors that must be kept dry during operation, which can be problematic when the product being pumped is a liquid.

The Solution

Taking all of the potential shortcomings in centrifugal pump operation into consideration, a much better choice for the numerous liquid-handling links in the carbonated soft-drink production chain is the AODD pump. Specifically, the Wilden
®SanifloHygienic Series (HS) and Saniflo FDA AODD Pumps from Wilden®Pump and Engineering Company, located in Grand Terrace, CA, USA, have been engineered to meet the highest standards for operation in the manufacture of carbonated soft drinks. Wilden, a global leader in the design and supply of AODD pumps for use in hygienic applications, is a product brand of PSG®, a Dover company, Oakbrook Terrace, IL, USA.

wilden

Among the many operational benefits that Wilden® Saniflo FDA Series AODD Pumps provide to soft-drink manufacturers are their availability in many materials of construction that meet U.S. Food & Drug Administration regulations for hygienic manufacturing.

Wilden’s HS and FDA AODD pumps possess the versatility to safely and efficiently pump a wide range of viscosities and shear-sensitive products, and are perfect for the corn syrups, phosphoric acids, concentrates and flavorings that play such a major role in the production of soft drinks. The HS model employs a straight-through flow design and both have Triclamp®-style fittings that ensure that desired flow rates are achieved. The wetted-path material is 316 L stainless steel with interior-polish levels that range from 0.8 to 1.3 μm (31.5 to 51.2 μin) for ease of cleaning.

Wilden HS pumps are some of the only pumps in the industry to have earned 3A certification for both clean-in-place (CIP) and clean-out-of-place (COP). The free draining flow path, wash-friendly clamp bands and CIP capability simplify cleaning, and have enabled Wilden’s HS and FDA AODD pumps to earn certifications from a number of regulatory agencies in the hygienic industry, including 3A, EHEDG, FDA CFR 21.177, USP Class VI and EC 1935/2004. Saniflo FDA models are also available in various materials of construction to meet FDA compliance in diverse applications.

The Pure-Fuse Diaphragm has been designed with an integrated stain-less-steel core that uses no adhesives or nylon fabric, which eliminates product-entrapment areas and greatly reduces contamination risks.

Other features and benefits of HS and FDA AODD pumps, which are available in sizes from 1/2” to 3” (13 mm to 76 mm), include:

  • Availability of multiple sanitary elastomers
  • Seal-less design for superior product containment
  • Delicate, shear-sensitive operation
  • Ability for self-priming or dry-priming operation
  • Damage-free dry-run capability
  • Flow rates from 15 to 245 gpm (57 to 927 L/min)
  • Solids Passage up to 3” (76 mm)
  • Highest energy efficiency on the market

Additionally, Wilden has also designed and developed next-generation diaphragm and air distribution system (ADS) technology that can be used to further optimize the operation and reliability of its HS and FDA pump models:

  • Pure-Fuse Diaphragms — This innovative design com-bines food-grade plastics and elastomers with a stain-less-steel core in a patented configuration that uses no adhesives or nylon fabric that can contaminate process fluids in the event of a breech. The diaphragm features an unbroken fluid-contact surface with no product-trap areas. As a result, Pure-Fuse has exceptional CIP capability and greatly reduces contamination risks. The elimination of the outer piston also reduces a common abrasion point, which results in longer diaphragm life. Finally, the Pure-Fuse’s large internal piston and full-stroke shaft provide greater fluid-transfer displacement while simultaneously allowing the pump to achieve twice the dry vacuum when compared to short-stroke CIP-capable diaphragms.
  • Stainless-Steel Pro-Flo® SHIFT ADS — The availability of the stainless-steel Pro-Flo SHIFT ADS allows the HS and FDA pumps to be used in a wider range of hygienic or sanitary liquid-handling operation in food-and-beverage manufacture.

The operation of the Pro-Flo SHIFT ADS also represents a major breakthrough in achieving energy-efficient operation for AODD Pumps. Thanks to its revolutionary design, the Pro-Flo SHIFT allows Wilden AODD pumps to achieve up to a 60 % savings in air consumption over competitive AODD pump technologies, while providing higher flow rates per SCFM. The Pro-Flo SHIFT also costs 50 % less to operate than electronically actuated ADS units, is submersible and features plug-and-play operation. It also has fewer operating parts, which equates to less downtime for repair or simple maintenance.

Conclusion

Though carbonated soft-drink consumption in the U.S. has been inexorably declining, it still remains the most popular drink among the country’s inhabitants. The category has also been buttressed with the new fruit-juice and energy-drink formulations that annually keeps it a multi- billion-dollar industry.

No matter the design or formulation of soft drinks, however, they will only resonate with the consuming public if they achieve long-held standards for appearance and taste. That puts tremendous pressure on soft-drink manufacturers to ensure that there is no deviation in the production process that may alter the formulas that are beloved by consumers. That’s why AODD pump technology, specifically the Hygienic and FDA from Wilden, are a wise choice for the many liquid- transfer points in soft-drink production and packaging. AODD pumps can help guarantee that product quality is preserved, while also adding the benefit of lower operating and maintenance costs to the bottom line of the producer.

Building Applications Knowledge Can Unlock Value in Pump Selection

Pumps & Systems

Leveraging this expertise solves customer problems and creates a sustainable competitive advantage.

By Nate Maguire, PSG

First of Two Parts

In industrial business-to-business equipment markets, manufacturers are faced with an increasingly difficult operating environment. Energy price volatility, the increasing costs of regulatory compliance and public demands for improved environmental stewardship with regard to scarce resources are three prominent factors now impacting industrial organizations around the world.

In confronting these challenges, manufacturers must adapt in numerous ways, including investing in next-generation technologies.

Smart supervisory control and data acquisition (SCADA) systems can reduce downtime through proactive monitoring, and energy-efficient pump technology delivers operating cost savings, hedges against energy-price fluctuations and helps companies meet their environmental stewardship goals by reducing carbon emissions.

However, the adoption of any new technology can dramatically increase the complexity of business operations at a time when cost pressures and economic headwinds threaten to curtail growth and profitability. Further, these technology investments require knowledge and expertise to build, operate and maintain. Many industrial producers, like most businesses, face resource constraints and are operating with leaner staffing levels than ever before. As a result, they are finding they do not possess the in-house expertise to effectively select, build, operate and maintain increasingly complex equipment and systems, and often are forced to turn to third-party organizations with specialized expertise for support.

Pump manufacturers in particular, along with their related distributors, engineering firms, consultants and other third parties, are stepping up to supply this critical applications expertise to end-user customers. Properly deployed applications expertise can unlock value for industrial producers, and organizations that build superior expertise in their markets can gain a significant competitive advantage.

The Challenge

Industrial manufacturers are facing an increasingly difficult business environment, one that is often impacted by these and other critical factors:

  • Energy-price volatility
  • Regulatory compliance legislation and associated costs
  • Public/customer expectations for enhanced resource stewardship

Energy-Price Volatility

Price volatility is defined in the energy industry as how quickly or widely electricity and/or natural gas prices change over a given time period.

Prices are governed by supply and demand, where demand is impacted by factors such as weather patterns, economic conditions and consumer behavior. In recent years, price volatility has increased in the energy market. To protect against this volatility, many companies “hedge,” or buy, a commodity at a price that is locked in over a set period of time.

wilden

While this may improve peace of mind for the operator, hedging is costly and doesn’t create value for the operator beyond reducing energy- cost volatility.

The severity and potential impact of price volatility is such that in its 2015 report titled, “The New Normal,” the World Energy Council (WEC) said, “The uncertain impact of volatile energy and commodity prices […] has now established itself as the number-one issue for energy leaders worldwide.”

The good news is that global energy leaders have recognized this challenge and are beginning to take measures to address it.

According to Francois Moisan in WEC’s triennial 2016 report, “Energy Efficiency: A straight path towards energy sustainability,” the increase in energy-efficiency legislation around the world “signifies a strengthening and consolidation of the industrial commitment to energy efficiency.”

The report does also indicate, however, that more “can and should be done to improve the efficiency of energy production and use.” This is noteworthy for industrial manufacturers because, as the WEC also points out, “industrial electric motors and electric motor-driven systems consume almost half of the total electricity and account for 70 percent of the total (amount of) electricity consumed in industry.”

For many industrial companies where energy represents a significant portion of operating costs, price volatility will continue to be a challenge. These companies will be self-served to evaluate energy-saving technology, but will only reap the greatest rewards if they do so by taking into account the intricacies of equipment in the specific applications in which they operate.

Only by developing and using the proper applications expertise will they be able to identify and choose the technology that is best suited to mitigate the cost risks associated with energy volatility.

wilden

Regulatory Compliance

Regulatory compliance is by definition a necessity for businesses in the modern world. These laws collectively shape the environment in which businesses operate. The number of federal regulations in the U.S. has been growing steadily for several decades, requiring more and more investments by many businesses in order to maintain compliance. In fact, a study by George Mason University shows that “the effects of federal regulation on value added to the (U.S.) GDP for a panel of 22 industries…over a period of 35 years…dampened (GDP by approximately) 0.8 percent per year since 1980, eliminating $4 trillion in growth by 2012.”

Two prominent examples in the industrial-manufacturing universe are the motor-efficiency regulations that have been developed by the U.S. Department of Energy (DOE) and the International Electrotechnical Commission (IEC) in Europe.

The bottom line is that regulations are an unavoidable requirement for doing business in almost any jurisdiction in the world.

Many advances in technology have been geared toward meeting the demands of a stricter regulatory environment (See Sidebar: Motoring Ahead), but will be optimized only if they are applied with the appropriate applications expertise. For example, the misapplication of a pump (for example, incorrectly sizing the pump for its application) will likely lead to far greater energy consumption than can be saved from improvements in motor technology.

wilden

Expectations for Resource Stewardship

A phrase that has gained stature over the past two decades in all forms of business is “corporate social responsibility,” or CSR, which is commonly characterized as “business practices involving initiatives that benefit society.”

An article in the June 18, 2016, issue of the International Journal of Business and Management titled, “Corporate Social Responsibility and Consumer Buying Behavior in Emerging Markets,” stated that “consumers now want companies to behave ethically in addition to providing quality product[s]...”

The obvious implication is that those companies that are perceived to be inattentive or irresponsible stewards regarding shared resources (for example, community water supplies or air quality) risk a political and social backlash that could impact the company’s standing and ability to do business in the communities in which it operates.

Therefore, it should not be surprising that a report from Harvard Business School titled, “The Impact of Corporate Social Responsibility on Investment Recommendations,” revealed that “recent research shows spending money on corporate social responsibility is no longer seen as a detriment to a company’s profitability. Stock analysts now view such expenditures as essential to a company’s long-term brand and value.”

To improve CSR standing, more and more companies are investing additional time and resources toward incorporating new technologies, changing operating practices and even adjusting business strategies to assuage the corporate-responsibility demands of the buying public.

Indeed, these resources can only be optimized by developing and applying expert knowledge of the business, its systems and the local environment in which it operates. Businesses that develop and use this knowledge will help satisfy the needs of the public while achieving positive outcomes in resource stewardship.

In summary, today’s industrial-equipment providers face an increasingly difficult operating environment, which includes energy price volatility, the increasing costs of regulatory compliance, and public demands for improved environmental stewardship.

To address these market dynamics and achieve positive business outcomes, many companies are purposefully developing and leveraging applications expertise, especially when selecting critical pumping technologies and systems.

Part 2 of this article, which will appear in the August 2017 issue of Pumps & Systems, will identify some of the best ways that applications knowledge can be gained and then implemented to develop the best pumping systems for unique—and critical—industrial-manufacturing applications.

These pumps also offer self-priming, dry run and deadhead capabilities, and are ideal for handling shear-sensitive products. In addition, Wilden Saniflo HS pumps are one of the few North American made AODD pumps that are validated by both 3-A in the area of CIP and EHEDG cleaning protocol.

Wilden Saniflo HS pumps are available in four sizes from 25 mm (1”) to 76 mm (3”) and feature flow rates from 144 lpm to 874 lpm (38 gpm and 231 gpm). These pumps are available with the Pro-Flo® SHIFT Air Distribution System (ADS) for outstanding energy efficiency. They also exceed all CE, ATEX, USP Class VI, 1935/2004/EC and FDA CFR 21.177 requirements.

Wilden will also have its Pure-Fuse Diaphragms on display in the booth. Pure-Fuse diaphragm technology incorporates a one-piece design that eliminates product-trap areas between the outer piston and diaphragm that can harbor bacteria, a critical consideration for food-and-beverage applications. This patented design also provides an unbroken fluid-contact surface for exceptional CIP capability and reduced contamination risks. Pure-Fuse combines food-grade plastics and elastomers with a stainless-steel core using no adhesives or nylon fabric that can contaminate process fluids in the event of a breech. In addition, by eliminating the outer piston Pure-Fuse diaphragms experience greatly reduced abrasion, which results in longer diaphragm life.

Wilden Pure-Fuse diaphragms are constructed of food-grade Wil-Flex™ (Santoprene™) that meets all FDA CFR 21.177, EHEDG, 1935/2004/EC and 3-A requirements. Wil-Flex features wide temperature limits, excellent flex life, high abrasion resistance and outstanding durability, even when handling acids, caustics and other aggressive fluids. Pure-Fuse diaphragms are available in 25 mm (1"), 38 mm (1-1/2"), 51 mm (2") 76 mm (3") sizes with a temperature range from -40°C to 107°C (-40°F to 225°F).
