ABSTRACT OF THE DISCLOSURE An air driven double acting diaphragm pump has a main pump body and circular pump housings disposed at opposite ends of the main pump body and rigidly secured thereto, said housings each having a frusto-conical inner wall and a concavo-convex outer wall. The outer wall has a radial chamber substantially tangential to the surface of the outer wall formed thereon, a circular diaphragm in each of said housings having removable clamp means for securing the inner and outer walls together and continuously gripping the periphery of the diaphragm therebetween to divide the interior of each housing into a pump chamber and a pump actuating chamber. A connecting rod extending through the main pump body co-axial with the pump housings connects the diaphragms together at opposite ends of the rod for reciprocatory movement of the diaphragms in unison within the housings, each end of the rod having piston assemblies for alignment of the diaphragms within their respective housings. A pilot valve assembly mounted within the main pump body actuable by the connecting rod piston assemblies for sensing the location of the piston assemblies within their respective pump housings, and a reversing valve assembly mounted on the main pump body actuable by the pilot valve assembly controllably supply a fluid under pressure to the pump actuating chambers. All inlet and discharge manifold disposed along a side of the main pump body straddling the pump housings and secured to the pump housings communicate the manifold to the radial chambers for ingress and egress of a liquid or a slurry to the said pump chambers, said manifold having a lower inlet and an upper outlet formed therein, vertically spaced- apart upper and lower horizontal plates and a vertical transverse partition joining said plates disposed within the manifold dividing the manifold into a lower common inlet chamber, an upper common outlet chamber, and a pair of horizontal chambers in communication with the pump chambers, in which check valve means formed in the upper and lower plates communicate the horizontal chambers with the common inlet and outlet chambers.
