Abstract: A pump system (1) includes a first (3) of at least one pump unit (3, 5) for pumping a fluid (11). The first pump unit (3) includes a pump, an electrical drive motor and a motor control, with a pump control for commanding the motor control. A sensor (7) with a sensor housing (27) and with sensor electronics (28) are located in the sensor housing (27) for detecting at least one parameter of the fluid (11) in the pump or in a pipe which is fluid-connected to the pump The pump control is integrated into the sensor electronics (28).

Abstract: A submersible pump assembly (1) includes a submersible pump (2) with a housing (3), and a sensor capsule (4) with a hermetically sealed casing (5). The sensor capsule (4) is releasably mountable at a sensor position (6) located at an outer face (7) of the housing (3) of the submersible pump (2). The submersible pump (2) includes a primary coil (8) within the housing (3). The sensor capsule (4) includes a secondary coil (9) within the casing (5). The primary coil (8) and the secondary coil (9) are arranged to be inductively coupled with each other for wirelessly transferring data and/or power through the housing (3) and the casing (5) when the sensor capsule (4) is mounted at the sensor position (6).
