Submersible Contractor Pump

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

The pump is suitable for pumping ?water with dirt from drainage pits ?water with sand from construction sites, excavation sites and tunnels

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 totally enclosed motor in insulation class F (155?C).

The pump has a rise pipe, a cooling jacket for continuous cooling of the motor by the pumped liquid and a high chrome stainless steel enclosed impeller to ensure high efficiency and maintained performance.

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

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 pump is fitted with suction strainer and 10 m cable.

The cable sealing consist of a rubber bushing, epoxy and rubber cover that eliminates the risk of water penetration in to the motor.

The pump is equipped with a hose coupling discharge.
