MKP-S – Stainless Steel Self-Priming Magnetic Drive Chemical Process Pump

Discover the benefits of the MKP-S produced by CP here - The self-priming centrifugal pump.


Special features

  • Suction tank integrated in the casing (=high operating safety).
  • Self-priming with a suction head of up to 8.5 m.
  • Suitable for efficient unloading of tanks (tanker trucks) with no outlet on the tanker floor.
  • Up to 30 % solids and 1 mm particle size can be pumped - depending on the nature of the particles.*


  • compact & virtually free of dead space
  • no shaft feedthrough & leak-free
  • single-part & central bearing
  • low bearing forces due to hydraulically balanced impeller
  • internal & external bearing lubrication options
  • high material flexibility
  • eddy-current-free shroud possible (=> reduced energy consumption)
  • inverted drive principle


  • heating possible

Assembly & repair

  • modular system made up of few individual parts
  • assembly friendly


  • DIN EN ISO 2858, 5199, 15783


  • EC Machinery Directive
  • EC Atex Directive

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