The inner plate includes membranes adapted for cooperation with plungers and/or valves of a membrane pump. The membranes include a main membrane, at least two valve membranes and an auxiliary membrane adapted to cooperate with a main membrane plunger, valve and an auxiliary membrane plunger of the pump, respectively.
