KZNRF Series

The KZNRF pumps have proprietary process hardened ductile iron volutes. It is the choice of industries that face the most difficult pumping: Lime slurries, mill scale, coal runoff sumps, wash down sumps, ash transfer, tailings ponds, slag pits, food wastes, silt removal, sand & gravel dewatering, barge & tank cleanout.

  • Every KZNRF Series slurry pump is constructed with the following abrasive resistant chrome iron components:
    • Agitator – Fluidizes settled solids into a slurry.
    • Wear plate – Replaceable hardened surface on the suction side where erosion would cause a loss of pump performance.
    • Semi-open impeller – Handles abrasive solid concentrations as high as 70% by weight.
  • Every KZNRF Series slurry pump model is protected by:
    • Class R motor insulation and built-in amperage (FLA) and temperature overload protection.
    • Double silicon carbide mechanical seals in a separate oil-filled seal chamber.
    • Heavy duty lip seal – additional protection for the mechanical seals.
    • Stainless steel shaft and shaft sleeve – Save on shaft wear due to abrasives and corrosion.
    • Hardened ductile iron volute – Proprietary plasma treated for extra hardness and long life.
  • Every KZNRF Series pump is a top discharge pump:
    • KZNRF severe duty slurry pumps are utility pumps and frequently dragged from one site to another. The KZNRF doesn’t have a side discharge connection that can break off or be damaged as it is pulled and pushed into place.
    • Top discharge pumps are cooled by pumped liquid – The KZNRF Series slurry pumps can pump a sump or pit down to within inches of the bottom. A side discharge pump without a cooling jacket must stay submerged to avoid overheating, leaving as much as three feet of unpumped slurry.
    • Top discharge means slim – Even the largest model with a 22.75-inch diameter will fit down a manhole with a hose attached.
    • The KZNRF’s proprietary-process hardened ductile iron volutes – cast with extra thick walls at the point where pumped slurry enters the discharge.
  • High-chrome agitator helps keep solids suspended in liquid and helps prevent pump from clogging.
  • Specifications dependent on model and may change without notice.
