Abstract
In a diaphragm (3) of a diaphragm press for separating liquid and solid materials by action of a pressure medium on the materials (7) via the diaphragm (3), the functions of sealing and retention are separated. This is accomplished by a dual embodiment of the diaphragm (3) in the form of a substantially sealing diaphragm seal (14) and a substantially retaining diaphragm carrier (13). A force transmission from drainage elements (6) in the press chamber (4) of a pressing vessel (1) of the diaphragm press to the diaphragm (3) can be accomplished by the diaphragm carrier (13) in a manner that treats the material gently. This substantially improves the service life of the diaphragm (3).
