Submersible drainage pump
The Grundfos DPK pump is a submersible pump for drainage applications.
The pump has a semi-open wheel with a free passage of 20 mm and allows the pumping of large amount of infiltration water and drainage water surface water with high pressure.
The compact design makes the pump available for a fixed or temporary installation.
The pump is cast iron with a radial back-up hole and a fully closed three-phase F-insulation class (155oC) engine.
The pump is equipped with ipsothermic sensors in case of engine overheating and an electrode probe to detect water penetration inside the engine.
The pump has a double mechanical pad.
The pump is ready, either for a free installation or for a seating installation. It is equipped with 10 m of cable.
