MKTP – Stainless Steel Magnetic Drive Chemical Process Sump Pump

Discover the benefits of the MKTP produced by CP here - The efficient and highly sump pump.


Special features

  • Sump pump for submersion depths down to 4 m.
  • Ball bearings that can be lubricated externally as an option (with patent).
  • Ideal for unloading tanks with no outlet on the tank floor.
  • Can be combined with injector for unloading larger containers as a tank unloading system
  • Solids possible*
  • Sophisticated bearing flushing offers reserves for difficult applications and high solids concentration in fluids.
  • Corrosive/toxic media are pumped in total safety (without fluid and vapours escaping into the environment).


  • compact & virtually free of dead space
  • no shaft feedthrough & leak-free
  • single-part & central bearing
  • no plain bearing carrier
  • eddy-current-free shroud possible (=> reduced energy consumption)
  • low bearing forces due to hydraulically balanced impeller
  • product-lubricated bearing eliminates common weak point on sump pumps
  • inverted drive principle


  • available with double-wall heatable discharge pipe

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.
