Abstract

Die Erfindung betrifft ein Membranpumpe mit einem Pumpendeckel (26), einem Pumpengehäuse (28) und einer zwischen diesen angeordneten hydraulisch angetriebenen Membran (10), welche einen Hydraulikraum (14) von einem Förderraum (12) abgrenzt und an einem umlaufenden Rand (30) eingespannt ist. Hierbei sind zwischen Pumpendeckel (26) und Pumpengehäuse (28) ein pumpendeckelseitiges Einsatzteil (34), welches den Förderraum (12) begrenzt, und/oder ein pumpengehäuseseitiges Einsatzteil (32) vorgesehen, welches den Hydraulikraum (14) begrenzt, wobei die Membran (10) an ihrem umlaufenden Rand (30) zwischen dem Einsatzteil (34 bzw. 32) und dem Pumpengehäuse (28) bzw. dem Pumpendeckel (26) oder zwischen den Einsatzteilen (32, 34) eingespannt ist.
