MKP – Stainless Steel Magnetic Drive Chemical Process Pump

Discover here the advantages of the MKP from CP – The highly reliable centrifugal pump for various applications.

Find out more about our MKP pump in our animation.


Special features

  • Up to 30% solids concentration and 1 mm particle size can be pumped – depending on the nature of the particles*


  • Unique drive and bearing concept
  • Compact & virtually free of dead space
  • Bearing frame & close-coupled design
  • No shaft feedthrough & leak-free
  • Low product content
  • No plain bearing carrier, no rotating shaft
  • Single-part & central bearing, on all sizes
  • Horizontal & vertical installation possible
  • Low bearing forces due to hydraulically balanced impeller
  • Internal & external bearing lubrication options
  • High material flexibility (casing, impeller as well as plain bearing materials)
  • Eddy-current-free shroud possible (> reduced energy consumption)
  • Inverted drive principle at flow rates up to approx. 200 m³/h
  • Single-stage centrifugal pump


  • Single-part heating chamber system
  • Very efficient heatability
  • Only 1 entrance and 1 discharge connection
  • Simple & easy to heat, a single heating jacket reduces installation costs
  • Low temperature difference in the pump & no cold zones thanks to excellent heat distribution
  • Short heating up time due to high thermal transfer efficiency & direct feed of the heating energy into the fluid space

Assembly & repair

  • Modular system made up of few individual parts
  • Assembly friendly

*In general, media with solids content can be transported, but application-specific verification in advance is necessary.
