Abstract

Die Erfindung betrifft eine Kreiselpumpe axialer oder halbaxialer Bauart, mit einem auf der Druckseite eines Laufrades gelegenen Leitrad (2), dessen im wesentlichen radial verlaufende Leitschaufeln (7, 7.x) mit einer Schaufelaußenkante (13) an einer strömungsführenden Wand (1.1) angeordnet sind, wobei die Eintrittskanten (6) der Leitschaufeln (7, 7.x) in Strömungsrichtung (8) zur Laufraddrehachse hin fliehend angeordnet sind und zwischen den Schaufelinnenkanten (12) der Leitschaufeln (7, 7,x) ein freier nabenloser Durchlass gebildet ist. Dabei sind die Leitschaufeln (7, 7.x) als Blechformteile gestaltet, wobei die Leitschaufel-Rohlinge als Abwicklung einer Kegelmantelfläche ausgebildet sind und die geformten Leitschaufeln Ausschnitte dieser Kegelmantelfläche sind (Fig. 1).
