VIKING HYGIENIC REVOLUTION SERIES PUMP MODEL R0300X FOR PUMPING LIQUID YEAST

Gentle Yeast Handling for one of the UK’s Leading Independent Breweries

For a yeast pitching application at one of the UK’s top independent breweries, we recently supplied these two stainless steel R0300X Circumferential Piston pumps from Viking Pump Hygienic.

The customer already had positive experience with the Viking Pump Hygienic Revolution Series which had outperformed other hygienic positive displacement pumps on the site. Each pump is mounted on a bespoke stainless steel baseplate and long coupled via a gearbox to 1.1 kW motor giving a pump speed of approximately 300 RPM - ensuring gentle, low shear handling of the yeast throughout the process.

Those working in the brewing, biotech, and food industries will know only too well that yeast is a product that needs to be handled with care. Liquid yeast can be surprisingly tricky to pump as it is a living, shear-sensitive suspension with unique flow and handling characteristics. Being shear sensitive it is susceptible to damage that can result in slow or incomplete fermentation. Also being a non-Newtonian fluid, yeast also presents the challenge of variable viscosity. These factors mean that the choice of pump type and capacity is critical.
