CRP

The CRP series pumps are perfectly cleanable air handling pumps, mainly utilised for pumping a mixture of liquid and air. They are constructed from thick, cold-rolled plate, ensuring they are 100% non-porous and extremely smooth. These pumps come with open or closed investment cast impellers, crafted from 316L or duplex materials. Thanks to their crevice-free design and electropolishing as the final surface treatment, the CRP series pumps are perfectly cleanable, rendering them a reliable component in your production process.

Pump series CRP

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