Abstract

The membrane pump (1) has a working membrane (3) oscillating between a lower and an upper dead center position, and a pump chamber (7) defined between the membrane and a concavely curved wall (6). The pump membrane has an inner and an outer annular zone (8,9) which are deformable during the pump movements. Between these sections is a stiffened section which does not deform during the pump's movements. The membrane in its non-deformed state is stiffened by radially orientated support ribs (10) which are spaced apart in the circumferential direction and located on the membrane underside furthest from the chamber wall.
