Abstract (en)
[origin: EP1179681A2] The immersion pump device has at least one immersion pump within a water-tight housing (1), together with an electric drive motor (4) for the pump wheel (11) which rotates in an open pressure chamber (9), with a pressure switch (23) for switching in the pump when the output pressure drops below a lower threshold and switching out the pump when the output pressure is above a higher threshold. The pressure switch is contained in a separate housing module (3) attached to the housing module (2) containing the pump and communicating with a pressure channel (19) provided by an intermediate space (18), with a sealed cable guide (24) between the housing modules for the connections between the pressure switch and the pump drive motor.
