Abstract (en)
[origin: WO0030841A1] The invention relates to a diaphragm (3) of a diaphragm press for separating liquid and solid substances by subjecting said substances (7) to the action of a hydraulic medium via the diaphragm (3), in which the sealing and holding functions are separated. To this end the diaphragm (3) is configured in two parts, notably a substantially sealing diaphragm seal (14) and a substantially holding diaphragm support (13). In this way the forces exerted on the diaphragm (3) by drainage elements (6) located in the pressing chamber (4) of a container (1) of the diaphragm press can be absorbed by the diaphragm support (13) without damage to the materials concerned. This significantly extends the useful life of the diaphragm (3).
