Submersible Dewatering Pump


Portable, slim-line top discharge submersible dewatering pumps are capable of handling contaminated fluids in the most severe and corrosive applications at construction sites, mines, power stations, steel plants, on ships and in aquaculture. The model DWP/DWPM pumps are available in either standard cast iron or 316 stainless steel. The high head models feature heavy-duty motors with oversized shaft and bearings.
