Open-pit drainage

Open pit drainage

Open-pit drainage is necessary to ensure that mining operations can continue unhindered. The grey water in open-pit mines typically contains abrasives such as stones, clay, sulphur, and the pH value can be 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 cast iron construction and narrow design characterises the Grundfos DWK range of dewatering pumps, and this pump is ideal for pits, for temporary or fixed installation and offers high-pressure pump performance unhindered by sand, small stones or other abrasives.

Grundfos can supply dewatering pumps for durable use and heavy flows that can be installed dry or submerged, available in higher-grade material anti-corrosion versions for severe conditions. Surface-mounted axel-driven pumps are also available, if the depth requirements are limited.

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.
