Pump series CRP

The pumps of the CRP series are perfectly cleanable air handling pumps and are mainly used to pump a mixture of liquid and air. Constructed in thick cold rolled plate, 100% non-porous and extremely smooth. The pumps have open or closed investment cast impellers, constructed in 316L or duplex materials.

Thanks to its crevice-free design and electropolishing as a final surface treatment, the CRP pump series are perfectly cleanable, resulting in a reliable component for your production process.

  1. Electropolished, easy to clean construction, no bacteria traps and no small clearances in order to clean the area around the O-ring
  2. Unique air handling design with cleanable air separator
  3. By-pass to casing taking care about air evacuation
  4. Monobloc execution with std. IEC motors

Application areas

Thanks to its unique air handling design based on a standard centrifugal pump, the CRP series are particularly suitable as a CIP return pump, as well as for unloading applications.

They are used in the most demanding hygienic applications in almost all industries such as dairies, breweries, beverage industry, distilleries, etc.
