MKPL-S – PFA Lined Self-Priming Magnetic Drive Chemical Process Pump

Discover the benefits of the MKPL-S produced by CP here - the corrosion and diffusion-resistant self-priming centrifugal pump - even at high temperatures.

Overview

Special features

  • Self-priming with a suction head of up to 8.5 m.
  • Suction tank integrated in the casing (=high operating safety).
  • No buffer liquid tank necessary (suction pipe is evacuated independently by means of a vacuum).
  • No problem with accumulation of air.
  • Metal reinforcement with thick, vacuum-tight, corrosion and diffusion-resistant PFA lining.
  • 100 % vacuum tight
  • PFA-lined plain bearing carrier

Construction

  • compact & virtually free of dead space
  • no shaft feedthrough & leak-free
  • single-part & central bearing
  • horizontal installation
  • open impeller with metal core
  • bearing made of pure SSiC (=highest operating safety)
  • plain and thrust bearings secured with polygonal form-fit, self-centring anti-rotation devices
  • plastic impeller firmly secured against rotating in the wrong pump direction
  • single-part, vacuum-tight, non-metallic shroud

Assembly & repair

  • bearing frame and motor can be dismantled (pump remains in the facility and is sealed to the outside)
  • modular system made up of few individual parts
  • assembly friendly

Standard

  • DIN EN ISO 2858, 5199, 15783

Directives

  • EC Machinery Directive
  • EC ATEX Directive
