MSKS - Solid PTFE Self-Priming Magnetic Drive Chemical Process Side Channel Pump

Discover the benefits of the MSKS produced by CP here - The self-priming side channel pump for gas content up to 25 % and suction heads up to 8.5 metres.


Special features

  • Thick, vacuum-tight, corrosion and diffusion-resistant solid plastic
  • Side channel impeller with metal core
  • Self-priming up to a suction head of 8.5 metres
  • Corrosion-resistant and hermetically sealed for fluids with a gas content up to 25 %
  • Accumulations of air in the suction pipe are no problem (=increased operating safety)
  • No electrostatic charging on the casing by using PTFE with carbon filler


  • Compact & virtually free of dead space
  • No shaft feedthrough & leak-free
  • Single-part & central bearing
  • Horizontal installation
  • Very rugged design
  • Nominal pressure PN 10
  • Enormous, solid and durable plain bearing made of pure SSiC
  • Can be made in PTFE with carbon filler, virgin PTFE, PVDF
  • Low wear due to axial and radial SSiC bearing
  • No buffer liquid tank, suction pipe is evacuated independently by means of a vacuum
  • Not damaged by incorrect rotational direction
  • Non metallic and eddy-current-free shroud (=reduced energy consumption)
  • Bump ring prevents damage to the shroud
  • Can be used as a monoblock, fixed or mobile

Assembly & repair

  • Modular system made up of few individual parts
  • Assembly friendly
