Abstract

Bei einer hydraulisch angetriebene Membranpumpe mit einer randseitig zwischen einem Pumpenkörper (2) und einem Pumpendeckel (3) eingespannten Membran, die einen Förderraum (4) von einem Hydraulikraum (5) trennt sowie in Richtung ihres Saughubes durch Federkraft vorgespannt ist, und mit einem hydraulischen Membranantrieb in Form eines oszillierenden Verdrängerkolbens (6), der im Pumpenkörper (2) zwischen einem Vorratsraum (8) für die Hydraulikflüssigkeit und dem Hydraulikraum (5) verschiebbar ist, ist die Anordnung derart getroffen, daß die Membran (1) mittels Federkraft so stark vorgespannt ist, daß sie eine beträchtliche Druckkraft auf die im Hydraulikraum (5) befindliche Hydraulikflüssigkeit ausübt und daß somit im Hydraulikraum (5) ein wesentlicher Überdruck gegen den Förderraum (4) aufgebaut ist.
