Abstract

Die Erfindung betrifft eine Zahnradpumpe, beispielsweise eine Lackpumpe. Die Abdichtung der aus dem Pumpengehäuse nach außen geführten Antriebswelle erfolgt durch eine mit einem Druckmedium beaufschlagtes Dichtmittel. Dieses Druckmedium ist unabhängig vom Fördermedium und kann mittels eines Kolbens unter Druck gesetzt werden. Ein Stellmittel, das direkt oder mittels eines weiteren hydraulischen Systems auf den Kolben wirkt, erlaubt die Einstellung des Drucks.
