Pumping surface water from the main level of the Indem open-cast mine into the receiving body of water
RWE Power AG, Braunkohletagebau Indem
The surface water, which arises discontinuously from the complete Indem open-cast mine, is first taken up in the main level. From here it is pumped continuously into the receiving body of water. Requirement to be satisfied by the pump: maximum delivery performance at pressure variations from 3,5 to 4,5 bar.
Use of a high-pressure pump of type LH855 with 55 kW. This delivers the water into the existing pressure line at the rate of 5,7 m3/min at a pressure of 3,5 bar. Since the Tsurumi pump can be operated not only vertically but also horizontally, it can be connected perfectly to the existing pressure line.
