ABSTRACT:
On a hydraulic diaphragm pump with a diaphragm including at least two individual layers, a dimensionally stable reinforcing element that moves together with the diaphragm and is kept in contact with the diaphragm is provided in the central area of the diaphragm. The inlet and outlet channels of the diaphragm pump open into the delivery chamber radially within the reinforcing element at least for the most part so the channels are covered accordingly by the reinforcing element.
