Features of the KZN Sludge/Slurry sump pump:

  • Corrosion resistant 410 stainless-steel shaft and stainless-steel shaft sleeve meaning a long service life, impact resistant and long lasting and easily replaceable shaft sleeves save on shaft wear
  • Multivane, semi-open, wear resistant, high chrome impeller with the ability to handle abrasive solid concentrations up to 70% by weight
  • A heavy duty high chrome agitator keeping the flow chamber and impeller clear by causing the solids to move in suspension, preventing the pump from clogging up
  • Double silicon carbide mechanical seals which are abrasion resistant, and the added protection of a heavy duty lip seal. Seals are located in a separate oil chamber to protect the motor.
  • Top discharge with a motor water jacket
  • the slimline design reduces the chance of damage to the outlet in transit and allows for pumping within inches of the bottom, without risk of overheating
  • Hardened ductile iron volute cast with extra thick walls (300 Brinnell hardness) which is twice as abrasive resistant as standard ductile cast iron, which ensures greater durability
  • Replaceable wear plate. A hardened surface on suction side inhibits the occurrence of erosion that could cause a reduction in pump performance
  • Large open strainer protecting larger solids from entering the pump
  • Lifting rings for easy lifting and transportation of the pump
