Abstract

Ein Laufrad (4) für eine insbesondere als Seitenkanalpumpe oder als Peripheralpumpe ausgebildete Förderpumpe (2) hat zwei drehfest miteinander verbundene Scheibenteile (8, 9). Die Scheibenteile (8, 9) lassen sich in einfach aufgebauten Formen beispielsweise im Spritzgußverfahren fertigen und mit nahezu beliebigen Geometrien von Leitschaufeln (12, 13) versehen. Durch die drehfeste Verbindung der Scheibenteile (8, 9) hat das Laufrad (4) eine hohe Stabilität.

An impeller (4) for a feed pump (2), which is designed in particular as a side channel pump or as a peripheral pump, has two disc parts (8, 9) connected to one another in a rotationally fixed manner. The disc parts (8, 9) can be manufactured in simple shapes, for example by injection molding, and can be provided with almost any geometry of guide vanes (12, 13). Due to the non-rotatable connection of the disc parts (8, 9), the impeller (4) is extremely stable.
