Abstract

Die Erfindung betrifft eine Rotationsverdrängerpumpe mit einem eine Grundplatte (3) mit einer Ringfläche (5) aufweisenden Stator (1), wobei sich die Ringfläche (5) zumindest über einen Teil eines Vollkreises erstreckt, wobei weiterhin in der Ringfläche (5) ein Zulauf (13) mündet und von der Ringfläche (5) ein Ablauf (15) abgeht, wobei weiterhin die Ringfläche (5) von einer Membran (11) zur Ausbildung eines Pumpkanals (12) überdeckt ist und wobei schließlich eine Kranz von einzeln gegen die Membran (11) sowie Ringfläche (5) beweglichen Druckübertragungsgliedern (14) insbesondere aus hochkant stehenden Plattenelementen vorgesehen ist, sowie mit einem über den Druckübertragungsgliedern (14) angeordneten sowie um die konzentrische Achse (4) der Ringfläche (5) umlaufenden Rotor (2), wobei der Rotor (2) mindestens eine Rolle (21) aufweist, welche auf der Rückseite der Druckübertragungsglieder (14) läuft und dadurch die Membran (11) derart fortlaufend lokal gegen die Ringfläche (5) drückt, daß die Membran (11) den Weg vom Zulauf (13) zum Ablauf (15) fortschreitend unterbricht und das Pumpmaterial vor sich herschiebt. Um die Neigung zur Verklumpung von heiklen Materialien beim Fördern herabzusetzen, wird vorgeschlagen, dass die Grundplatte (3) zur Bildung der Ringfläche (5) entlang des Pumpkanals (12) eine Lage aus einem weicheren Material als jenem der Grundplatte (3) trägt.
