KBZ Submersible Drainage Pump

The body of motor and pump is made of rigid cast iron for long-lasting durability.
Greatly increased maximum submersion depth due to mechanical seal resistant to high pressure.
Semi-open impeller made of high chrome alloy match with wear plate(ductile iron)achieves superior durability.
Effective motor cooling due to discharge channel cast as part of the motor housing.Space economically by a top outlet.
Discharge 50mm(2” )to 150mm(6”),motor 1.5kW(2HP)to 15kW(20HP).
Hermetically sealed motor equipped build-in thermal protection for the power below 15kW.
