Abstract (en)
[origin: EP0947702A1] The motor/pump group, includes a motor (3) driving an impeller (4), a liquid sealed motor casing (5) and an electrical control unit (6) designed to control the motor as a function of the liquid level in a volume (C) in which the motor/pump group is placed. Liquid level is detected by a sensor (7). The control unit is sealed to prevent ingress of liquid and is fitted to the motor casing. The unit is supplied with electrical current via a cable (8), and it includes a signal generator (14), which, on receipt of a signal from the sensor, sends through the cable to another similar motor group.
