DW submersible contractor pump - dewatering and drainage



The Grundfos DW pumps are robust, portable submersible pumps with a vertical discharge port.
Available with motors from 0.8 to 20 kW, they are designed to handle dewatering at construction sites, at excavation sites, in building drainage and in similar applications where there is a need to pump raw water or/and at high pressure.
DW main parts are made of aluminium in order for them to be as light as possible. This factor, in combination with the compact design and the high-pressure capabilities, make DW pumps portable and easy to handle. The semi-open type impeller is made of high-chrome stainless steel (550HB) in order to increase wear resistance. DW.50.08 (only) has a polypropylene motor housing.


DW pumps are excellent for dewatering and draining jobs. The portable design, wear resistant parts and high pressure capabilities ensure the reliability, sustained performance, user-friendliness and ease of servicing that are necessary in demanding dewatering applications at sites such as:  

  • Construction sites
  • Excavations
  • Tunnels
  • Steel works
  • Fish ponds
  • Underground parking drainage
  • Industrial drainage pits.
