ABSTRACT:
A flexible diaphragm for an air driven diaphragm pump having a circular configuration with an inner attachment portion, an outer attachment portion and an annular flexure portion bounded by transition portions to the inner and outer attachment portions. The annular flexure portion is configured with a constant radius of curvature concave on the air chamber side. The curvature is such that the center of curvature lies substantially within a plane also including the transition portion between the annular flexure portion and the inner attachment portion. The diaphragm is molded in this shape to avoid the creation of internal stress and permanent strain resulting from use of the diaphragm. Fabric is positioned across the diaphragm closest to the air chamber side and being about one-third of the total thickness of the diaphragm from the air chamber side of the diaphragm.
