Abstract: A pump control method for controlling at least one booster pump (4). The method includes switching on the booster pump when a booster pump outlet pressure (24) drops to a lower limit value (26), and switching off the booster pump when the booster pump outlet pressure (24) reaches an upper limit value (28). The lower limit value (26) is reduced in a case, in which the maximal outlet pressure (24a) which can be reached on operation of the booster pump (4) lies below the lower limit value (26). A pressure-boosting device is also provided with which the pump control method can be carried out.

Abstract: A pressure boosting device increases pressure of a fluid flowing through a conduit (5) and includes a booster pump (2), a control device (12), controlling the booster pump (2), as well as a pressure sensor (8) arranged at the exit side of the booster pump (2) and connected to the control device. The control device (12) is configured to control the booster pump, in an operating region, in a start-stop operation, a switching off of the booster pump (2) when reaching an upper pressure limit value (P1) and a switching on of the booster pump (2) when reaching a lower pressure limit value (P2). The control device (12) is further configured in a start-stop operation to automatically adapt at least one pressure control parameter (P1, P2) of the control device (12) on the basis of the temporal course of at least one pressure value (P) detected by the pressure sensor.

Abstract: The invention relates to a pump assembly with a pump and with an electrical drive motor, as well as an electronic control device. The electronic control device includes a rotation direction recognition module for recognizing the correct rotation direction (CW, CCW) of the drive motor and of the pump. The rotation direction recognition module detects at least one performance characteristic value (H, Q, P) of the pump assembly, and is designed in a manner such that on rotation of the drive motor, the rotation direction recognition module detects at least one performance characteristic value (H, Q, P) and determines the correct rotation direction (CW, CCW) by way of evaluation of the performance characteristic value (H, Q, P).
