MKPL – PFA-Lined Magnetic Drive Chemical Process Pump

Discover the benefits of the MKPL produced by CP here – the corrosion and permeation-resistant centrifugal pump – even at high temperatures.

Their casing is lined with high quality, corrosion and permeation-resistant PFA. The thick PFA lining is anchored vacuum-tight to the metal reinforcement. This absorbs the mechanical loads caused by the system pressure or by pipeline forces. The intelligent modular system makes assembly easier and reduces the costs for spare parts, maintenance and repair to a minimum.

Overview

Special features

  • Metal reinforcement with thick, vacuum-tight, corrosion and permeation-resistant PFA lining
  • 100 % vacuum-tight
  • PFA-lined plain bearing carrier
  • Medium temperature up to 200°C max.
  • Up to 10% solids concentration can be pumped – depending on the nature of the particles*

Construction

  • Compact & virtually free of dead space
  • No shaft feedthrough & leak-free
  • Single-part & central bearing
  • Horizontal installation
  • Open impeller & closed 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
  • Single-stage centrifugal pump

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

*In general, media with solids content can be transported, but application-specific verification in advance is necessary.
