Abstract

Die Erfindung betrifft eine Membranpumpe (109) mit einem Pumpengehäuse (1), an dem eine Einwegzelle (2) lösbar fixierbar ist, die eine erste und eine zweite Zellwand (3, 4) hat, welche (3, 4) einen Arbeitsraum (5) zwischen sich umgrenzen, und mit einer Arbeitsmembran (6), die (6) mit einem oszillierenden Hubantrieb in Antriebsverbindung steht und die (6) auf ihrer dem Hubantrieb abgewandten Membranflachseite mit der flexiblen ersten Zellwand (3) lösbar koppelbar ist. Für die erfindungsgemäße Membranpumpe (109) ist kennzeichnend, dass in der Arbeitsmembrane (6) zum Entleeren des zwischen ihr und der ersten Zellwand (3) angeordneten Schadraumes (11) wenigstens ein Auslasskanal (12) mit einem Rückflussbehinderer oder einem Rückflussverhinderer vorgesehen ist (vgl. Fig. 1).
