KZNF Heavy Duty Submersible Slurry Pumps with agitator is the choice of industries that face the most difficult pumping of liquids and solids.
- EVERY KZNF slurry pump is constructed with the following abrasive resistant 28% chrome iron (600 Brinell, 57 Rockwell C) components;
- Agitator - to fluidize 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 - to handle abrasive solid concentrations as high as 70% by weight.
- EVERY KZNF 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 – saves on shaft wear due to abrasives and corrosion.
- Pump volutes cast from hardened Ductile Iron - 300 Brinnell hardness; twice as abrasive resistant as standard ductile iron.
- EVERY KZNF is a top discharge pump;
- KZNF heavy duty slurry pumps are utility pumps; frequently dragged from one site to another. The KZNF 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 KZNF 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 3 feet of un-pumped slurry.
- Top discharge means "SLIM" - even the largest model with a 22.75 inch "waistline" will fit down a manhole with a hose attached.
- The KZNF’s 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 & may change without notice)
