Submersible Contractor Pump

Grundfos DWK pump is a submersible pump for dewatering and drainage applications.

The pump is suitable for pumping ?large quantities of underground and surface water ?drainage water at high head ?water with dirt from drainage pits

The pump design makes it suitable for both temporary and permanent installation.

The pump is cast iron, with vertical discharge port and integrated submersible 3-phase enclosed motor in insulation class F (155?C).

The pump has a riser pipe, a cooling jacket for continuous cooling of the motor by the pumped liquid and an enclosed impeller to ensure high efficiency.

The pump is equipped with a double mechanical seal and an additional lip seal that protects the shaft and the mechanical seal against abrasives.

The pump is fitted with suction strainer and 10 m cable.

The pump is equipped with a temperature Bi-metal sensor for motor protection in case of overheating and electrode seal sensor to detect water penetration in to the motor housing.

The cable sealing consists of a rubber bushing, epoxy and rubber cover that eliminates the risk of water penetration into the motor.
