Australian brewery eliminates downtime by pumping yeast with a Verderflex pump

With a gentle pumping action and a great ability to pump solids, the Verderflex VF50 peristaltic pump has been selected for use in an Australian brewery for pumping yeast with 30% solids. Yeast is a shear sensitive product and must be handled carefully, damage; will reduce the quality of the beer.

Due to the naturally gentle pumping action of peristaltic hose pumps, Verderflex are able to pump shear sensitive products such as yeast and not damage the product, resulting in a brewery happy to use the VF50 pumps in their yeast room.

A common problem in this type of application is that the fluid (yeast), being highly abrasive, can lead to stator or impeller wear and result in long and very costly downtime, loss of production and ongoing maintenance costs. The easy to change, long life Verderflex food grade NBRF hose is abrasion resistant and in order to maximise uptime, it has been designed for an extended fatigue life. The Verderflex peristaltic hose pump has been suitably engineered to ensure that the production does not suffer from these costly downtimes.

This pump has two duties: one for recirculating yeast around the pitch yeast tank. The second duty is to pitch yeast from the pitch yeast tank into the wort line which goes to the beer fermenters. When yeast is transferred or re-circulated in a process, the lines may become empty and pumps can run dry. The design of the Verderflex hose pump, with its external lubrication eliminates the need for expensive hygienic dry running protection.
