ABSTRACT:
A diaphragm pump with a flat diaphragm which is held between the face surface of a pump head and the corresponding face surface of a hydraulic block is improved in that the annular clamping region has an angling step such that the clamped-in diaphragm is bent in its outer annular border region. In this way, a sealed tightness is achieved over long time periods, as well as inducing a uniform diaphragm tension which effects performance of the pump advantageously. Inventive valve designs are provided which allow removal for cleaning from outside the assembled pump and also allows manual /pening of the valves for unclogging. An efficient design is provided for a pump head.
