Zusammenfassung:A separating membrane includes: a planar edge region for the joining of the separating membrane to a diaphragm seal body; a working region offset in an axial direction relative to the edge region; and a transition region between the edge region and the working region, wherein the transition region extends over a radial region of not more than one quarter of an outer radius of the transition region, wherein the working region has a substantially planar center and an embossed pattern or undulation pattern between the center and an outer edge of the working region, wherein from the rest position to a point of deflection with a dimensionless pressure equivalent, the separating membrane has a characteristic curve in which, for a coefficient of determination R2 of a linear regression of the characteristic curve, the following applies: (1−R2)
