CP Pumpen AG

Model MKPL – PFA - Lined Magnetic Drive Chemical Process Pump



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
