Choosing a pump for hygienic liquid food handling

12 April 2018

Atlantic Engineering is a Belgian OEM specialising in dispensing technology for the food industry, particularly liquid and semi-liquid foodstuff. Products being handled varies from aqueous substances like brine, to viscous meat mixtures such as pie fillings. 

After observing how one a client produced meals for hospitals, manually pouring hundreds of litres of soup into lidded buckets or bags, the company went on to develop its Innofill concept to offer a better solution for such applications.

Innofill is based on dispensing, filling and safely sealing liquid products in one move, making them suitable for the cook and chill process. By utilising this method, fresh produce can be kept for up to 40 days without loss of quality. The success of the solution relied on the right pump, and the Maso Sine Certa pump from Watson-Marlow Fluid Technology Group (WMFTG) was specified.

Cédric De Bleye at Atlantic Engineering, explains why: “Pumps play an important role in all of our systems. We use many different pumps because they have specific properties and advantages. One of the main reasons we chose the Certa sine pump is because it’s the only one that can do everything we need for the Innofill concept.”

The four most important pump requirements for Innofill included virtually no pulsation and consistent, accurate flows. The pump also has to be hygienic and easy to clean with minimal downtime. Gentle handling of viscous fluids, including particles and large pieces of food ingredients, wasa further prerequisite. High temperature resistance was also necessary as the pump would be connected to boilers.

“Only the Certa pump could offer us all of these capabilities – and the price-to-quality ratio was good as well – which is why it was the only logical choice,” continued De Bleye. Certa delivers gradual flow without pulsation, which is important in order to dispense accurately and package the product correctly – without foaming or loss of integrity. Because only a few parts of the pump come into contact with the food and the entire pump can be cleaned quickly using CIP or SIP. A further benefit is that the pump has only one changeable part, so spares inventory is minimal and maintenance downtime is reduced.
