The largest submersible motor pumps
ANDRITZ has delivered the largest ever built submersible motor pumps. The pumps, each consisting of three individual components, are 22 meters long or rather high and weigh more than 32 tons when mounted. Thus, they are roughly four times higher than the Giant Heart in Philadelphia, USA, which is five meters high. In a Chinese mine, the pumps are installed at a depth of 900 meters, hanging freely on the pipe. A pump unit conveys 1000 m2/h to a height of 1000 m. The two larger submersible pumps provide 4 megawatts (4000 kW) each and even the smaller one 3.2 megawatts (3200 kW). The units are the heart of the mine’s safety device and shall prevent that the tunnels, in which the miners work, are flooded.
