MKPP – Stainless Steel Magnetic Drive In-Line Chemical Process Peripheral Pump

Back to Product Guide

  • Peripheral pump for high head at low flow rates
  • Ingeniously simple pump design with just a few, robust components
  • Pump body constructed from non-porous bar stock
  • Central bearing assembly eliminating the need for a plain bearing carrier
  • Use of a single product-lubricated bearing that overcomes the common weak point of conventional pumps
  • Axial and radial SSiC bearing for low wear
  • No rubbing of the peripheral impeller on the casing
  • Vast choice of materials of construction ranging from high-alloy stainless steel, nickel and nickel-base alloys to other special alloys
  • In-line installation for maximum space saving
  • Simple and low-cost installation
