Abstract
A reinforced high-volume elastomeric pump diaphragm features several concentric circumferential reinforcing ribs (areas of increased thickness) integrally formed in the angled wall. Two ribs extend from the exterior to the interior. One rib, nearest the rim of the diaphragm, extends only to the exterior. This particular arrangement of ribs reduces rolling and appreciably improves performance by prolonging the useful life of the diaphragm.
