    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 non-return valve (19) for a water supply system (1) or a pump (4) is integrated in a flow channel (14) of the water supply system (1). The non-return valve (19) includes a sealing body (21) which is mounted within the channel (14), blocks the channel (14) in a first position forming the closure position and releases the channel (14) in a second position forming the opened position. The sealing body (21) is movably arranged on a holder (31) which includes a closure body (15), with which the holder (31) is releasably fastened in a housing opening.

    Abstract: A centrifugal pump assembly has an electric drive motor (2) and at least one impeller (10; 10′), which is movable in an axial direction (X) between at least two functional positions. In one functional position a flow path through the impeller (10; 10′) is essentially closed and in another functional position the flow path through the impeller (10; 10′) is opened. The impeller (10; 10′) in a first functional position is held by a magnetic force (FM) or a spring force and in a second functional position is held by a hydraulic force (FH) produced by a delivered fluid. An impeller is provided for the centrifugal pump assembly.

    Abstract: A hydraulic heating and/or cooling system hydraulic manifold is constructed in a modular manner with a main module (2). At least one load module (4) is connectable to the main module (2) and includes a hydraulic connection (22, 24) for a load circuit, and a closed-loop control device (26, 28) controlling flow through the load and for connection to an identically configured further load module (4). The at least one load module (4) includes a circuit board (44) which extends between a first (34) and a second axial end (36) of the load module (4) and which at its first (34) and second end (36) have electrical couplings (50, 52) which correspond to one another. The electrical coupling (52) at the second end (36) of the circuit board (44) can electrically conductively engage with an electrical coupling (50) at the first end (34) of the further identical load module (4).

    Abstract: A coupling has an input-side coupling part (1) and an output-side coupling part (2), which are connected to each other in a torque-transmitting manner in such a way that the coupling parts can be moved to a limited extent. The output-side coupling part (2) has a rod-shaped body (10) rigidly connected to the output-side coupling part, which rod-shaped body extends in the direction of the axis of rotation (9) of the coupling and is surrounded by a hollow body (5) rigidly connected to the other coupling part (1). Sensor elements (11, 12) are provided, by which the radial distance between the rod-shaped body (10) and the hollow body (5) is detected during the rotation of the coupling.
