Product waste in hygienic manufacturing industries such as food and beverage, pharmaceuticals and cosmetics has long been accepted as an unavoidable “cost of doing business.” The problem with this mindset is that simply flushing or draining away raw ingredients or intermediate/finished products that remain in suction and discharge piping at the conclusion of production runs or during product changeovers is the same as watching money go down the drain.

The key, therefore, to turning product “waste” into product “recovery” – and, by extension, “profit” recovery – in these situations is identifying and deploying the most efficient and reliable pumping technology, one that can be trusted to strip suction and discharge lines of still useable raw materials and saleable end products. While such technologies as lobe, external circumferential piston (ECP), twin screw, centrifugal, hose and progressive cavity-style pumps have routinely been used in hygienic manufacturing, their operational capabilities have been found wanting when it comes to optimizing product recovery.

A better, more reliable and more efficient choice is the Eccentric Disc Pump. The pump’s unique operating principle – a disc revolves on an eccentric plane within a circular channel – gives it the ability to function in a non-pulsing, low-slip manner with high volumetric consistency. Eccentric disc pumps are also able to pump air, which creates a vacuum effect on the suction side and a compressor effect on the discharge side, resulting in the ability to push a complete product “plug” out of the piping without the need for expensive pigging systems or other line-clearing solutions.

There are numerous and wide-ranging instances where eccentric disc pumps have been introduced to hygienic-manufacturing operations with resulting notable improvements in product-recovery rates and overall operational costs. Let’s take a closer look at several examples:

Winemaking

Bailly Lapierre, Saint-Bris-le-Vineaux, France, is one of the world’s preeminent producers of Crémant de Bourgogne, a white or rose sparkling wine made predominantly from Pinot Noir and Chardonnay grapes. When the winemaker recently decided to upgrade its facility with state-of-the-art equipment, it chose eccentric disc pumps for use in several of the winemaking stages. All of these stages require high, non-pulsing flow rates with strong volumetric consistency and minimal slip.

When selecting pumps, wine producers should choose a pumping technology that possesses the ability to recover expensive products and ingredients from the tank and piping systems. This is why Bailly Lapierre chose to install Mouvex® SLS Series Eccentric Disc Pumps.

“Eccentric disc pumps have many benefits for us,” said Mathieu Cerveau, a cellarman at Bailly Lapierre. “We produce between four and five million bottles of wine each year, and an eccentric disc pump fills each and every one. We wouldn’t be able to operate without them. The high flow rates are a key feature; since we deal with big volumes of liquid, we need a big flow. Another great feature is the strong suction. Because the pump is located in the pressing area, it has to suck the liquid from a lower level and send it through about 40 meters of piping. This isn’t possible with some other pumps. Additionally, just as we have designed our presses to handle the grapes as gently as possible, we love the fact that eccentric disc pumps feature no excessive shear that puts friction on the wine. But the best benefit for us is the higher rate of product recovery. These pumps can completely drain all of the juice from the piping and from inside the tanks.”

Ice Cream

The evolving combination of a strict manufacturing process and a change in the makeup and viscosity of finished ice cream products recently caused ice cream manufacturer Ysco, Langemark, Belgium, to question the use of centrifugal pumps in its operations. The higher viscosities required stable, non-pulsating flow and high volumetric consistency that centrifugal pumps just aren’t able to deliver, with the result being inefficient operation that would lead to excessive product waste. The solution was a seal-less eccentric disc pump that would reduce the risk of product contamination and leaks while maximizing product-recovery rates.

The SLS Series Eccentric Disc Pump from Mouvex® is able to overcome the challenges presented by higher-viscosity ice cream formulas, while also possessing the operational characteristics that make enhanced product recovery possible.

“The eccentric disc pump is idiot-proof, which is very important since we are running 24 hours and everyone has to handle it,” said Krist Levrouw, Engineering Assistant at Ysco. “It has to be simple to use, simple to clean and simple to maintain. Every step in the process is important. Every step is complicated, but the eccentric disc pump makes life easier. No stress.”

Cosmetics

Headquartered in Tokyo, Japan, cosmetics giant Shiseido has operations all over the world. Its European operation located in Ormes, France, transfers up to four tons a day of high-value raw materials for the manufacture of perfumes, face and body creams, shower oils and gels, and liquid makeup removers. Ensuring gentle handling while minimizing the loss of these expensive components is a daily challenge for the site and one that eccentric disc pumps have been able to reliably meet.

“In our process we need to have as little loss as possible because the product is really expensive,” explained Sophie Guermond, the facility’s Lean Manager. “One kilo of product can cost €30 to €40 (US$33 to $44), so if in each batch we lose 50 kilos (110 pounds), the price adds up really fast. It’s also really important that there is very little shearing of the product because the creams need to have a specific texture. When the cream is in the tank and passing through the eccentric disc pump, we need the least amount of loss as possible. Because of their operation and reliability, we don’t have any daily worries with the eccentric disc pumps.”

Soft Drinks

Optimizing product quality, operational sustainability and manufacturing costs are the driving forces at Coca-Cola’s Hellenic Bottling Company (HBC) plant in Dunaharaszti, Hungary. A key link in the facility’s production chain involves the unloading of tankers that are laden with the raw ingredients that will be transformed into popular drinks like Coke, Sprite, Nestea Iced Tea and Powerade sports drinks. Recently, the twin screw pumps tasked with these unloading responsibilities were having difficulty performing them without freezing up, which would delay the plant’s strict “just in time” production schedules. The solution: replacing the screw pumps with highly efficient and waste-averse eccentric disc pumps.

Sustainability is integrated across every aspect of Coca Cola HBC’s business as the company
looks to be a leader in the industry in terms of customer service and cost efficiency. Coca-Cola
HBC prides itself on the fact that its 59 production plants, 289 filling lines and 292 warehouse
and distribution centers operate in the most environmentally sensitive and cost-efficient way
possible.

“The reliability of the equipment is very important because we provide high-quality products and to create them we need high-quality equipment,” said Zoltán Marincsák, Maintenance Manager for the Coca-Cola HBC Dunaharaszti facility. “With the eccentric disc pump, we eliminate waste, we reduce water and energy consumption, and our maintenance costs are reduced. 

“Food safety is critical because it’s a hygienic industry and it’s very important that there are no seals where foreign material can enter the system, so the hygienic design of the eccentric disc pump is very important,” he said. “Although there was a strong argument to justify integrating the pump into the system, the key selling point was the recovery of pure concentrate and the contribution to the facility’s sustainability goals. There used to be more than 300 kilograms (660 pounds) left in the truck and pipe system with the old pump. With the eccentric disc pump, less than 100 kilograms (220 pounds) remain in the pump and the piping system. So, if we reduce waste by 200 kilograms per load and recover more than one ton, that saves thousands of euros.”

Baked Goods

A large United States-based baked-goods manufacturer that produces nearly 600 products in its expansive manufacturing facility was having problems with a leaking pump. A circumferential piston pump that was being utilized to distribute chocolate coating over cookies was experiencing leaks every two weeks that would result in the loss of 100 pounds of coating and a time-consuming interruption in the production process. The problem was solved by replacing the ill-performing pump with a seal-less eccentric disc model outfitted with pressure and flow switches that would eliminate the leaks and improve operational efficiency.

“Dealing with a leaking pump is one extra headache you just don’t need,” said the plant’s Maintenance Manager. “It’s nice to get the right pump for the right application and the eccentric disc pump is very low maintenance. I would definitely install another eccentric disc pump in the future.”

Brewing

By 2012, Surly Brewing, Brooklyn Center, MN, had grown into one of the nation’s most significant craft brewers, forcing it to upgrade and expand its manufacturing operation. The new beer-making equipment, along with Surly’s unique brewing method that does not involve any filtration, led to the search for a pumping technology that could steadily push the beer through the production process in an even, non-pulsating manner. Diaphragm and centrifugal pumps weren’t able to satisfy those operational demands, and rotary lobe pumps were too maintenance-intensive, but a satisfying solution was found in the eccentric disc pump.

“We’re seeing consistent yield increases with the eccentric disc pump,” said Surly’s Head Brewer. “We don’t need downtime. This pump just works and does what it’s supposed to do.”

Conclusion

With operational budgets tightening, manufacturers of food and beverage, pharmaceutical and cosmetic products that rely on hygienic systems would be wise to determine how much cost savings can be realized in targeted product recovery. The fulcrum in optimized product recovery is the pump that is used to transfer raw materials or finished products through the suction and discharge lines. The ultimate solution in this area has proven to be the eccentric disc pump, which, by its method of operation, offers the line-clearing and -stripping capabilities that other pump technologies can’t deliver, resulting in less product waste and improved cost-effectiveness.
