Abstract (en)

The motor-pump set has a pump (1) driven by an electric motor (2) that is controlled by an electrical circuit (3), where current passing in the circuit exceeds a given threshold during starting of the motor. A clock (8) activates an alarm (10) when the current does not exceed the threshold for a given period of time ranging between 30 minutes and 24 hours. The unit has a current measurement device (5) connected to a comparator (6). Another clock (9) activates the alarm when the current continuously exceeds the threshold for another given period of time.
