Abstract

Die Erfindung betrifft eine Doppel - Innenzahnradpumpe (1) mit zwei Innenzahnradpumpen (2, 2'), die eine gemeinsame Pumpenwelle (3) aufweisen. Die Erfindung schlägt vor, eine Trennwand (10) zwischen den beiden Innenzahnradpumpen (2, 2') mit einer kegelstumpfförmigen Umfangsflache (12) auszubilden, die dichtend an einer Gegenfläche (13) in einem Pumpengehäuse (6) anliegt. Durch die Trennwand (10) können Pumpeneinlässe und Pumpenauslässe geführt sein.
