Abstract: A centrifugal pump assembly includes an electric drive motor (6, 8), a driven impeller (14) and a pump casing (2) which surrounds the impeller (14). A movable element (24; 24′) is arranged a valve element. A section of the valve element is movable from a released position into a bearing position, fixed on a contact surface (60), by pressure which is produced by the impeller in the pump casing. A control device (64) moves the valve element from one switching position into another switching position and reduces the speed of the drive motor. Upon pressure in the pump casing dropping such that the valve element is no longer fixed on the contact surface and the valve element has been moved into the other switching position, the control device increases the speed of the drive motor again. A method for moving a valve element is provided.

Abstract: A hydraulic construction unit for a heating facility or air-conditioning facility, includes a return connection (20) and a first feed connection (16) for a heating circuit (6), with a heat source outlet (12) fluid conducting connected to the return connection. A heat source inlet (14) is fluid conducting connected to the first feed connection and to a circulation pump assembly (28) in a flow path between the return connection and the heat source outlet (12) or in a flow path between the heat source inlet and the first feed connection. A second feed connection (18) for a second heating circuit (8), is fluid conducting connected to the heat source inlet and to the return connection. A mixing valve (54) is arranged in a flow path from the heat source inlet to the second feed connection and/or in a flow path from the return connection to the second feed connection.

Abstract: A pump assembly includes an impeller (18), which for rotation is connected to an electrical drive motor (20) which can be driven in two rotation directions (A, B) and a valve (10) situated in an inlet of the pump assembly. The valve includes a valve element (48) movable between at least two switch positions and is connected for movement to a drive element (36, 60) subjected to the flow produced by the impeller (18). The valve element (48), in at least a first of the two switch positions, closes an inlet channel (44, 46) of the pump assembly (12) and is arranged such that the movement direction into this first switch position corresponds to the flow direction (S1, S2) through this inlet channel (44, 46). A hydraulic system is provided with two circuits and such a pump assembly. The valve serves as a switch-over valve between the two circuits.

Abstract: A hydraulic valve device includes a first inlet port (20) and a second inlet port (22) and a valve element (24) for selectively closing one of the first and the second inlet port. The valve element (24; 24′) is rotatable between two valve positions such that a surface of the valve element is moved in a direction parallel to openings of the inlet ports. The valve element includes two separate sealing portions (72, 74), a first sealing portion (72) for closing the first inlet port and a second sealing portion (74) for closing the second inlet port. The two sealing portions are arranged such that in a first valve position a first sealing portion closes the first inlet port and in a second valve position a second sealing portion closes the second inlet port. A centrifugal pump device includes such hydraulic valve device.

Abstract: A centrifugal pump assembly includes an electrical drive motor (2), with at least one impeller (18) which is driven by the motor and a pump casing (6) which surrounds the impeller (18) and which includes at least one suction connection (20) and at least two delivery connections (22, 24). A rotatable valve element (30, 30′, 30″) is arranged in the pump casing (6). The valve element is movable between at least two switching positions, in which the flow paths through the delivery connections (22, 24) are opened to a different extent. The valve element (30, 30′, 30″) includes an annular wall (32) which surrounds the impeller (18) and in which at least one switching opening (48) is formed. The valve element (30, 30′, 30″) is rotatably mounted about a rotation axis (X), which is centric to the annular wall (32), inside of the pump casing (6).
