MKP-ANSI – Magnetic Drive Chemical Process Pump

Discover the benefits of the MKP produced by CP here – the highly safe centrifugal pump for various applications.

Find out more about our MKP pump in our animation.

Overview

Special features

  • Up to 30% solids concentration and 1 mm (1/25") particle size can be pumped – depending on the nature of the particles*

Construction

  • Close-coupled design
  • No shaft feedthrough & leak-free
  • Low product content
  • Free of dead space
  • 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
  • Single-stage centrifugal pump

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.
