ABSTRACT:
A double diaphragm pump having an air chamber housing centrally located between two water chamber housings. The air chamber housing includes a center section and two outwardly facing concave discs. Each water chamber housing includes a water chamber shell mating with one of the discs with a flexible diaphragm therebetween. Also included integrally formed with the water chamber housing are check valve chambers and inlet and outlet passages. The passages of one water chamber mutually converge with the passages of the other water chamber to receive T-couplings for providing both inlet to and outlet from the pump. O-rings are held in interference fit between the T-couplings and the mutually converging portions of the inlet and outlet passages. Shoulders on the T-couplings and portions keep the O-rings in place. Spacing inserts are employed in each passage to locate either a valve seat or a ball check valve and to close off access openings through the wall of the chamber. Two clamp bands are positioned about the mating peripheries of the discs and water chamber shells to hold the entire unit in the assembled condition.
