Abstract
The fluid section of an air operated double diaphragm pumpconsists of two fluid housings, an inlet manifold, and an outlet manifold. The housings are to be made in two parts. The preferred framematerial is glass fiber reinforced with polypropylene that is overmolded into final shape with an encapsulating material. The frameis designed so that the encapsulating materialcan flow from one side to the other allowing for a mechanical lock between the top surfaceand the bottom so as not to rely on chemical adhesion between the two materials.
