Abstract (en)
[origin: EP2357363A1] The operation controlling device comprises a pump motor with an actuation unit (12), particularly for setting the rotational speed for the pump motor, and a state sensor unit (20) for detecting an actual operating parameter, particularly operating pressure of the positive-displacement pump (14). An operating mode unit (18) is provided, which is configured, such that an actuating mode for the pump motor is set by the actuating unit below an operating-parameter threshold value. The operating-parameter threshold value is fixed or is calculated as a value or a pump parameter which is correlated.
