摘要： A centrifugal pump comprising a motor with a shaft rotatably extending therefrom and an adapter configured to be mounted to the motor at a first side, the first side including an opening for permitting passage of the shaft therethrough. A volute housing is configured to be mounted to a second side of the adapter, the adapter and volute housing defining a pumping chamber therebetween. An impeller is configured to be disposed within the pumping chamber and rotatably coupled to the shaft via a figured fastener. The impeller includes a first wall having a figured recess defined therein, the figured recessed configured to receive the figured fastener whereby rotation of the shaft causes rotation of the impeller.

摘要： A pump assembly comprises an inlet (10) having an open end, an outlet (12) having an open end and a housing (11) having an inlet aperture (31) in fluid connection with the inlet (10) and an outlet aperture (32) in fluid connection with the outlet (12). A rotor (37) is located within the housing (11) and shaped to form with an interior surface of the housing at least one chamber (28a, 28b) that on rotation of the rotor (37) conveys fluid from the inlet aperture (31) to the outlet aperture (32). The housing (11) carries a seal (24) located in the inlet (10) and urged into contact with the rotor (37) to prevent the passage of fluid past the rotor (37) from the outlet (12) to the inlet (10). The inlet (10) and the outlet (12) have respective centre lines that are parallel to one another and normal to the axis of the rotor (37). The outlet (12) forms a guide path for linear movement of a mould core (52) for forming the outlet (12) and the outlet opening (32) and the outlet aperture (32) being so orientated that the direction of opening of the outlet aperture (32) does not face away from the open end of the outlet (12). This allows the outlet (12) and the outlet opening (32) to be formed using a single simple mould core (52) travelling in a linear path.

摘要： The invention relates to a sealing arrangement for a high-pressure space having a bounding element and a termination element. The bounding element has an outer sealing surface and the termination element has an inner sealing surface. The outer sealing surface and the inner sealing surface are arranged such that a sealing-off of the high-pressure space is achieved via a contact of the two sealing surfaces. In accordance with the invention the bounding element is designed such that a force in the direction of the inner sealing surface can act on the outer sealing surface due to a pressure in the high-pressure space. Thereby a sealing function is also achieved then when the termination element deforms due to the pressure in the high-pressure space. The sealing arrangement in accordance with the invention can be used particularly advantageously in pumps.
