Davey – Extra Heavy Duty Dewatering Sump Pumps

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

Applications:

• Ground & nuisance water removal

• Drainage from dams, sewer systems, tunnels, river improvement projects & construction sites

• Pumping of muddy liquid generated from industrial projects

features & Benefits

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

KZN models 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
