SJT (Geo) for geothermal production hot water

The simple yet effective hot water pump for geothermal

Sulzer SJT (Geo) are designed for geothermal production in shallow wells. The pump can be adapted to the optimum length to pump hot water at the needed output flow.

  • Production pump for geothermal plants
    Geological characteristics ask for smart pumps that offer flexibility in the construction to suit their place of action. In shallow wells with less than -650m water level, the line shaft vertical pump configuration is preferably used. It's major advantages are the adaptability and simplified maintenance.
