Abstract

Eine Strömungsleiteinrichtung (25) für eine Impeller-Radialpumpe ist radial außerhalb des Impellers angeordnet und ringförmig umlaufend mit einem umlaufenden Trägerring (27), an dem mehrere Leitschaufeln (29) angeordnet sind. Diese sind derart elastisch ausgebildet, dass bei geringem Fluidstrom ein Anstellwinkel mehr in radiale Richtung weist mit einem Winkel von etwa 70° zur Längsmittelachse der Pumpe. Bei starkem Fluidstrom wird der Winkel kleiner und die Leitschaufeln (29) biegen sich zumindest bereichsweise elastisch ab, so dass sie mit einem kleineren Winkel zwischen 30° und 40° zur Längsmittelachse der Pumpe stehen. So wird das Fluid besser in der Pumpenkammer gefördert.
