Pump series IRP

These air handling pumps have stainless steel 316L pump casings constructed in thick cold rolled plate, 100% nonporous and extremely smooth. The pumps have open or closed investment cast impellers, constructed in 316L or duplex materials. Together with an electropolished design the industrial air handling pump series IRP are a reliable component into your production process.

  1. Unique air handling design with cleanable air
  2. By-pass to casing taking care about air evacuation
  3. Monobloc execution with std. IEC motors

Application areas

Thanks to its unique air handling design based on a standard centrifugal pump, the IRP series are particularly suitable as a CIP return pump, as well as for unloading all type of collecting tankers and trucks.



Your benefits

  • Higher pump efficiency compared with a classic liquid ring pump
  • Low NPSH values: less risk on cavitation
  • Electropolished: higher resistance against corrosion
  • Easy & robust construction, easy to install and easy maintenance: less downime
  • Construction without non-return valve
  • Easy to install
  • 2 mechanical seal diameters for the entire range
  • Limited noise level
