Abstract

The pump contains cylinders (1) which are arranged in the form of a star and which are attached to a molding (12) with valve cartridges (8 and 9) being interposed. This molding (12) consists of two sets of pipes (17 and 18) which are arranged in the form of a star. The suction channels (13) of the pump are formed in one of the sets of pipes (17). The delivery channels (14) are formed in the other of the pipe sets (18). The central ends of the suction channels (13) open into a cavity (15) which is located in the center of the molding (12) and which is provided with a screw sleeve (16) for attaching a suction line. The central ends of the delivery channels (14) are connected to one another in flow terms, and one of the delivery channels (14) is provided with an outflow orifice (23) for the fluid. The use of the molding mentioned makes it substantially simpler to connect the individual parts of the pump to one another and to the lines attached to the pump.
