Abstract

Die Erfindung betrifft eine Umwälzpumpe (1) für einen Geschirrspülautomaten, mit ersten Druckstutzen (4, 5) und einer Wasserweiche (6), wobei die Wasserweiche (6) einen Drehschieber (7) zum Sperren und Freigeben der ersten Druckstutzen (4, 5) und einen Antrieb (8) für den Drehschieber (7) aufweist. Um eine Umwälzpumpe (1) der eingangsgenannten Art bereitzustellen, die bei gleichzeitig vereinfachtem Aufbau eine verbesserte Absperrung ermöglicht, wird mit der Erfindung eine Umwälzpumpe (1) der eingangsgenannten Art vorgeschlagen, die durch eine mit einem ersten Druckstutzen (4) oder einem zusätzlichen Druckstutzen (9) zusammenwirkende Ventileinrichtung (12) gekennzeichnet ist, wobei die Ventileinrichtung (12) ein mit dem Antrieb (8) für den Drehschieber (7) betätigbares Ventil (11) aufweist.
