Abstract:
A diaphragm pump for a pumped shower waste, comprises a diaphragm housing (12), a diaphragm (34) removably held in the diaphragm housing (12), an openable cover (16) on the diaphragm housing (12) for accessing the diaphragm (34), an electric motor (14), a connecting member (40) positioned in the diaphragm housing (12) and movable by the electric motor (14), and a non-screw-threaded twist and lock fastener (62) which releasably engages the diaphragm (34) with the connecting member (40). The diaphragm (34) can thus be disengaged and removed from the connecting member (40) without the use of a screwdriver.
