MKPL – PFA Lined Magnetic Drive Chemical Process Pump

Back to Product Guide

  • Pump dimensions to DIN EN ISO 2858
  • Metal casing with a thick vacuum-, corrosion- and permeation-resistant PFA lining
  • Bearing assembly made of pure SSiC in a robust design engineered for ceramics
  • PFA lined metal plain bearing carrier maintaining a constant clearance between the impeller and casing, even at high temperatures
  • Plain and thrust bearings secured with polygonal form-fit, self-centring anti-rotation devices
  • Plastic impeller firmly secured to prevent loosening in case of reverse pump rotation
  • One-piece, vacuum-resistant, non-metallic containment shell
  • Open impeller with a metal core for low NPSH
  • Closed impeller with a metal core for high efficiencies
  • Modular system consisting of few components
