A major German brewery was looking for a pump to transfer liquid containing diatomite. The brewery uses diatomite as a filtering aid. The yeast and turbidity are filtered out of the beer in three phases. In the separation process of the centrifuge, the diatomite filtration is performed followed by filtration through cellulose layers.
To pump the diatomite filtered liquid mixture to a collection tank, the brewery needed a pump. It was important for the brewery to have a robust, high performance pump. A Boerger Rotary Lobe Pump was chosen.
The casing of the Boerger pump is made of duplex stainless steel. Due to the extremely abrasive medium, the pump is fitted with replaceable casing protection plates and liners. The Boerger Rotary Lobe Pump has been operating at the customer for almost 10 years now. Maintenance work can be performed in a matter of minutes by the brewery's own staff thanks to the low maintenance Boerger pumps.
