Abstract: A double-diaphragm pump includes a pair of axially spaced apart pumping chambers, each chamber having a pumping diaphragm which divides each chamber into an inner and outer compartment. Inner ends of both pumping chambers are closed by a central element, and fluid is supplied to the outer compartments to cause the diaphragms to oscillate and vary the capacities of the inner compartments. I Each of the inner compartments having an inlet and an outlet port leading to unidirectional valves to allow fluid to be drawn into one of the compartments when the appropriate diaphragm moves outwardly and expelled from that compartment when the diaphragm moves inwardly. The unidirectional valves are located in inlet and outlet manifolds in the central element and are accessed and fitted through the inlet and outlet ports in the inner compartments.
