Grundfos DWK pump is a submersible pump for dewatering and drainage applications.
The pump is suitable for pumping
|
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.
