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. In the case of a pump unit (1) for liquid pumps, consisting of a plastic impeller (2) with a metallic hub (3) and a mechanical seal, is the Counter ring (4) in a recess (7) of the Plastic impeller (2) arranged such that it with its back surface in heat-conducting system for Radial leg (10) of the hub (3) is. This will ensures a temperature dissipation to the shaft (8), which prevents the plastic impeller (2) from melting.
