The Grundfos DP is a rugged submersible drainage pump built for reliable removal of groundwater, surface water and lightly contaminated drainage water. It uses a semi-open multi-vane impeller with a 10 mm free passage to handle water carrying sand and small particles, and a robust cast-iron hydraulic assembly for long service life in demanding installations. Available across the DP10.50 to DP10.65 range with motors from roughly 0.9 to 2.6 kW, it delivers dependable performance for both portable and permanent duties. Applications include construction-site dewatering, basement and pit drainage, groundwater and surface-water removal, and general drainage in commercial and industrial buildings.
