The right food grade pump is in the application detail

15 November 2021

From dosing ingredients on the production line to transferring the finished product to removing waste fluids, the food and drink industry rely heavily on pumps to deliver their process. When sourcing a pump, it’s essential to understand that a pump that works isn’t necessarily the right pump – what works in one application, isn’t necessarily ideal for another.

After almost 15 years specifying pumps to food and drink manufacturers worldwide, Castle Pumps understand how the right pump is in the detail of the application…

IT STARTS WITH AN ENQUIRY
Castle Pumps received an enquiry from the WooHa Brewing Company, a brewery based in Scotland looking for a hygienic pumping solution for a beer transfer application. The customer wanted to be able to transfer large volumes of beer throughout the factory, as it could be required to pump out any tank at any time. A portable solution was therefore vital as rather than being installed in one fixed position, they needed to be able to transport it to various points around the brewery.

As well as application details, when specifying a pump, it is vital to have performance requirements to work off. The engineer at WooHa was able to provide Castle Pumps with the desired flow rate and pressure capabilities required for efficiently transferring the beer.

GETTING THE RIGHT SOLUTION
When specifying a pump for the food and drink processing industry, of course the first place to start is ensuring that the solution is food grade an easy to clean. 

Castle pumps selected a flexible impeller pump with an EPDM food grade impeller and mechanical seal and a Stainless Steel 316 casing. The standard BSP inlet and outlet were also swapped for for tri-clamp connections, meeting the ISO 2852 standard for couplings within the food industry, as they have minimal area for bacteria to congregate. 

The flexible impeller design is an extremely versatile solution, available at lower costs than other food grade pumping technologies. The beauty is that its reversible operation allows the user to quickly clean the pump between uses by running a cleaning solution through it. 

To satisfy the brewery’s requirements for a portable solution, Castle Pumps supplied the pump mounted onto a company and lightweight trolley, allowing it to be transported to wherever beer transfer is required.

Within two days of the pump being delivered, Castle pumps received a warmly welcomed sample of beer produced at the Wooha Brewery. They were so pleased with their purchase and wanted to give a taster of some of the beer that their new pump would be helping to efficiently produce.
