Abstract

A diaphragm pump has opposed pump chambers separated by a reciprocatory diaphragm 1 and each chamber has a pressure connection 10, (11) and a vacuum connection (12, 13). The pressure connections (10, 11) are connected together by channels (24, 26) within the pump housing 2 and so also are the vacuum connections. The diaphragm is clamped between supporting plates 4, 5 each having an external contour substantially complementary to that of the chamber wall 2, 3 facing it so that in operation dead space within the chamber is minimised. <IMAGE>
