The housing of a centrifugal pump is made of sheet metal and has a spherical or conical shell with a flange at one end and an inlet in the other end. The inlet is surrounded by a composite or one-piece collar having openings for the shanks of bolts which secure the housing to a fluid supplying pipe. The nuts for such bolts are confined in sockets which are provided in the outer side of the shell opposite the collar. The flange is connected to a bearing block or to the casing of a block motor, and the shell can contain an insert which is integral with the inlet and can carry a sealing ring for the impeller.
