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.

Find out more about our MKP pump in our animation.

Overview

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 concentration and 1 mm particle size can be pumped – depending on the nature of the particles.*

Costruction

  • 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
  • Single-stage centrifugal pump

Heatability

  • Heating possible

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.
