SUBMERSIBLE PUMP

摘要

The invention relates to a submersible pump (10) comprising a pump housing (12) which can be immersed into a liquid that is to be evacuated and is provided with a suction inlet (39) and a pressure outlet (41). The liquid can be sucked into the housing via the suction inlet and can be discharged under pressure via the pressure outlet. The inventive submersible pump further comprises an electronic control unit which is coupled to a sensor unit (58) located on the outside of the housing and is configured so as to turn the submersible pump on and off in accordance with the level of the liquid that surrounds the pump. In order to further develop said submersible pump such that the same can be produced at a lower cost and is fitted with a structurally simpler sensor unit, the sensor unit is embodied as a structural unit that is retained on the pump housing in a vertically adjustable manner and encompasses a sensor housing (61) inside which two electrodes (62, 63) are arranged at a distance from one another. Said two electrodes (62, 63) can be moistened with liquid.
