ABSTRACT:
A safety diaphragm for a diaphragm pump, which makes it possible to detect a rupture of the diaphragm during operation or when at a standstill. The diaphragm has at least two diaphragm layers (1, 2) arranged lying one on top of the other The diaphragm has a clamping region (E) for fixing the diaphragm in a pump and has an adjacent operational region (A). The diaphragm layer (1, 2) are connected to each other so that they are sealed against penetration of liquid and/or gas between the diaphragm layers (1, 2). The diaphragm, in one section of the clamping region (E), has a sensor region (S) where the diaphragm layers (1, 2) are formed so that, in the case of an increase in pressure between the diaphragm layers (1, 2), the layers in sensor region (S) deform more easily than in the other sections of the diaphragm.
