Abstract

1. Diaphragm for hydraulically-controlled diaphragm pump of which two faces are in contact with two different fluids, said diaphragm forming a cup-shaped member (1) which is substantially spherical and comprises an annular outer edge (2) substantially plane, said diaphragm being characterised in that it is constituted in a manner known per se, by two layers, one (3) in rubber and the other (4) in plastic material such as tetrafluor-ethylene and in that each of the faces of said edge is provided with a bead (2a, 2b) by which the diaphragm is secured in the pump body.
