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.

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