MKPP – Stainless Steel Magnetic Drive In-Line Chemical Process Peripheral Pump

Discover the benefits of the MKPP produced by CP here - The space-saving peripheral pump for high delivery heads and low flow rates.

Find out more about our MKP pump in our animation.

Overview

Special features

  • Peripheral pump for low flow rate and high pressure
  • Ideal for dosing and injection tasks

Construction

  • Compact & virtually free of dead space
  • No shaft feedthrough & leak-free
  • Single-part & central bearing
  • In-line installation for optimal use of space
  • Pump body made of non-porous bar stock
  • No plain bearing carrier
  • Using a single product-lubricated bearing eliminates common weak point on conventional pumps
  • Low wear due to axial and radial SSiC bearing
  • No rubbing of the peripheral impeller on the casing
  • Low bearing forces due to hydraulically balanced impeller
  • High material flexibility (casing, impeller as well as plain bearing materials)
  • Single-stage centrifugal pump

Assembly & repair

  • Modular system made up of few individual parts
  • Assembly friendly
  • Simple & low-cost installation
