Underground dewatering/drainage



Underground dewatering and drainage is necessary to ensure that mining operations continue unhindered. Dewatering from rock faces in mine shafts, quarries, or gravel pits often contains abrasives such as sand, clay particles, drill cuttings, and other potentially damaging objects, and the pH value is usually very low. Grundfos dewatering pumps are designed to work in the toughest environments and can be found in mining applications and offshore industries worldwide.

Solid construction with high-grade materials such as chromium steel and silicon carbide means the Grundfos AP range of dewatering pumps is ideal for pits, for temporary or fixed installation, and offers high-pressure pump performance unhindered by sand or other abrasives. Solid cast iron construction and narrow design characterises the Grundfos DWK range of dewatering pumps, and this range can pump small stones at greater flow than the Grundfos AP range.

The Grundfos SE/SEV series of pumps are specifically designed for durable use and heavy flows and can be installed dry or submerged. Higher-grade material anti-corrosion versions are also available for severe conditions.

Correct material selection is the most important method of corrosion prevention, prolonging the life span of pumps systems. Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Furthermore, Grundfos tailors commissioning agreements and service agreements to your requirements, and spare parts kits and on-site recommended spare parts can also be arranged.
