KZNRF Series:

CAST IRON:

KZNF Heavy Duty High-Temperature Submersible Slurry Pumps with agitator 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

TOP 3 REASONS WHY YOU SHOULD CHOOSE THE KZNRF…

1. EVERY KZNRF slurry pump is constructed with the following abrasive resistant chrome iron components;
1. Agitator - to fluidize settled solids into a slurry.
2. Wear plate - replaceable hardened surface on the suction side where erosion would cause a loss of pump performance.
3. Semi- open Impeller - to handle abrasive solid concentrations as high as 70% by weight.
2. EVERY KZNRF slurry pump model is protected by;
1. Class H motor insulation
2. Double silicon carbide mechanical seals - in a separate oil filled seal chamber.
3. Heavy Duty Lip Seal – additional protection for the mechanical seals.
4. Stainless steel shaft and shaft sleeve – saves on shaft wear due to abrasives and corrosion.
5. Pump volutes cast from hardened Ductile Iron - 300 Brinnell hardness; twice as abrasive resistant as standard ductile iron.
3. EVERY KZNRF is a top discharge pump;
1. KZNRF heavy duty slurry pumps are utility pumps; 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.
2. Top discharge pumps are cooled by pumped liquid - The KZNRF 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.
3. Top discharge means "SLIM" - even the largest model with a 22.75 inch "waistline" will fit down a manhole with a hose attached.
4. The KZNRF’s hardened ductile iron volutes - cast with extra thick walls at the point where pumped slurry enters the discharge.
