Abstract

Eine Vakuumpumpe, insbesondere Drehschieberpumpe, umfasst wenigstens eine Pumpstufe zum Pumpen eines Fluids von einem Einlass der Pumpstufe zu einem Auslass der Pumpstufe, einen Sumpf, insbesondere Ölsumpf, für ein Betriebsmittel, insbesondere ein Öl, zum Schmieren und Abdichten der Pumpstufe, und wenigstens einen Kanal zur Führung des Betriebsmittels in der Pumpe, wobei der Kanal eine Mündung in den Sumpf aufweist, die unterhalb eines für das Betriebsmittel vorgesehenen Mindestpegels liegt.
