A double-acting air-powered diaphragm pump having a pair of identical pump assemblies detachably secured within a frame-like manifold assembly. Each of the pump assemblies contains a pair of mating halves and a web-like resilient diaphragm defining an air cavity and a fluid cavity. Each of the diaphragms is operated by means of a centrally attached shaft, the facing ends of the shafts being joined by a chain link which allows for potential misalignment. The pump assemblies, which are substantially identical in construction, may be easily and individually removed from the manifold assembly for repair or replacement.
