The pump (1) has a housing (10) defining a working space containing at least one pump wheel. The wheel is rotated by an electric drive motor (2) and at least one control disc (11), with at least one suction opening (12) and at least one pressure opening (13), cooperating with a side plate (15) for defining a suction space and a pressure space. The housing, the side plate, the suction and pressure connections (18,19) and the control disc are all provided by a single metal casting. The casting has a seating for receiving a seal for the pump wheel drive shaft (7).
