Pump series PRP2

The pumps of the PRP2 series are perfectly cleanable 3A certified air handling pumps and are mainly used to pump a mixture of liquid and air. These perfectly cleanable pumps have stainless steel 316L pump casings constructed in thick cold rolled plate, 100% non porous and extremely smooth. The pumps have fully machined open impellers constructed in 1.4435 material. Thanks to its crevice-free design and electropolishing as a final surface treatment, the PRP2 pump series are perfectly cleanable, resulting in a reliable component into 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. Fully drainable
  5. Monobloc execution with std. IEC motors

Application areas

Thanks to its unique air handling design based on a standard centrifugal pump, the PRP2 series are particularly suitable as CIP return pump!



Your benefits
