Abstract

Bei einer Pumpeneinheit (1) für Flüssigkeitspumpen, bestehend aus einem Kunststofflaufrad (2) mit einer metallischen Nabe (3) und einer Gleitringdichtung, ist der Gegenring (4) in einer Ausnehmung (7) des Kunststofflaufrades (2) derart angeordnet, daß er mit seiner Rückenfläche in wärmeleitender Anlage zum Radialschenkel (10) der Nabe (3) steht. Hierdurch wird eine Temperaturabführung zur Welle (8) gewährleistet, die ein Schmelzen des Kunststofflaufrades (2) verhindert.
