Abstract

L'invention concerne l'industrie du transport de matériaux fluides. Pompe centrifuge comportant un rotor à une pale, dans laquelle le bord extrême 6 de la pale s'étend en direction de la paroi 3 du carter de manière que sa projection dans le plan horizontal forme un angle aigu avec la paroi 3 du carter et que sa projection 6a dans le plan vertical forme un angle aigu avec un plan axial perpendiculaire à la paroi du carter, le bord 7 de la pale côté refoulement se terminant devant la paroi 3 du carter par un bord frontal 8 s'étendant entre la pointe 8a du bord extrême de la pale et le moyeu 1 du rotor, qui est incliné, en formant un angle aigu, par rapport au plan horizontal. Application notamment au transport de matériaux renfermant des solides à fibres longues.
