PU MPS CAN PUMPS GO ON AN ETE RNAL MISSION? SUSTAINABLE PUMPING TECHNOLOGY Responsible water management, in particular, is one of the most crucial, eternal missions – work that will be needed long after a mine’s closure. A German mining company plans to let the acid mine water rise to a point where there is still a safety margin to the groundwater. The current solution with centrifugal pumps requires a dry underground machine room. Addition- ally, pumping large volumes of liquid from great depths generates up to 30 tons of axial thrust that have to be eliminated. ANDRITZ suggested dou- ble-suction submersible motor pumps that are maintenance-free, compen- sate the axial thrust and achieve high energy savings.
