Abstract

Die Erfindung betrifft ein Laufrad einer Kreiselpumpe mit mindestens zwei Schaufeln (4) zur Förderung von feststoffhaltigen Medien. Erfindungsgemäß ist der Schaufeleintrittswinkel (ß1) kleiner 0°. Der Schaufelwinkel (ß) steigt in einem ersten Abschnitt (9) an bis er einen Wert von 0° erreicht. In einem zweiten Abschnitt (10) erfolgt ein weiterer Anstieg bis ein maximalen Wert erreicht wird. In einem dritten Abschnitt (11) fällt der Schaufelwinkel (ß) wieder ab.
