Abstract (en)

The impeller(4) consists of at least two disc sections(8,9) lying one above the other and interconnected but torsionally fixed in relation to each other. The disc sections are interconnected outside the centre of the impeller. One of the disc sections may have a protruding collar accommodated in a recess formed in the opposite disc section. The disc sections may have a form-locking torsionally fixed interconnection, or a spigot may be provided on one section to press fit into a hole in the other section.

Abstract (de)

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. <IMAGE>
