Grundfos DW Heavy Duty Contractor Pump
The Grundfos DW pumps are capable of pumping water containing abrasive materials such as sand and clay particles, drill cuttings, and other potentially damaging objects that could be found on rock faces, at construction sites or in mine shafts.

The Grundfos DW heavy duty contractor submersible pump range is built to last longer than conventional dewatering pumps. This is achieved through extensive use of high-grade materials such as chromium steel, nitril rubber, silicon carbide (SiC/SiC) and aluminium alloy. Various protection devices minimise potential system damage caused by overheating, whilst an integrated level switch (optional) monitors water level and automatically starts and stops the pump.
