ABSTRACT:
A diaphragm pump including a reciprocating piston engaging at opposite ends a pair of diaphragms which close opposite ends of a cylinder is disclosed. The piston ends engage the respective diaphragms across the entire dimension of the cylinder so that the membranes act as seals between the piston and the cylinder, thereby preventing unequal distortion of the diaphragm and enabling the pump to generate high pressure.
