Davey KZN Sludge and Slurry Pumps

Davey KZN Sludge and Slurry Pumps

Davey commercial and heavy duty, sludge and slurry pumps



KZN models are heavy duty, top discharge, dewatering pumps designed for very dirty water and farm wastes. They have a heavy duty inlet agitators and are suitable for pumping sludge and slurries.

  • Able to pump water containing up to 70% soft solids by weight in suspension. 
  • Flow up to 375 m2/hr / 6,000lpm
  • Designed for ground & nuisance water removal; drainage from dams, sewer systems, tunnels, river improvement projects & construction sites; pumping of muddy liquid generated from industrial projects.

 

Why choose the KZN Sludge/Slurry sump pump?

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