The invention relates to an exchangeable pump cartridge (200) for a membrane pump, comprising a base body (300) and a cover body (500). A pump membrane (410) is arranged between the base body and the cover body. The pump membrane and the cover body define together a working chamber. Valve flaps (420, 430) of an inlet valve and an outlet valve are also arranged between the base body and the cover body, laterally from the pump membrane. Said base body and the cover body respectfully have surfaces facing the valve flaps. Recesses, forming the laterally extending fluid channels (521, 531) between the inlet valve, the working chamber and the outlet valve, are arranged in the aforementioned surfaces. Additionally, a filter membrane (600) can be integrated into the pump cartridge. The pump membrane comprises a blind hole-like opening (412) for joining to a connecting rod of a drive module. |
