Abstract

Die Erfindung beschreibt eine Seitenkanalpumpstufe mit auf einer Welle (10) befestigten Rotorelementen (12) und Statorelementen (14a, 14b), welche mit den feststehenden Teilen der Pumpe verbunden sind. An den Rotorelementen sind auf einem oder mehreren konzentrischen Ringen Schaufeln (16, 18) angeordnet. In den Statorelementen (14a, 14b) sind ein oder mehrere konzentrische Kanäle (22a, 24a) eingearbeitet, in welche die Schaufeln der Rotorelemente eingreifen. Die Kanäle können so angeordnet sein, dass sie eine parallele Gasführung oder, mit Hilfe von Verbindungskanälen (30), eine serielle Gasführung erlauben.
