Abstract

L'invention concerne une roue (10) pour pompe centrifuge présentant une direction axiale (X), la roue (10) comprenant un moyeu (24), un voile (26) ayant une forme de révolution comprenant une partie de fixation (28) du voile (26) avec le moyeu (24), le voile (26) s'évasant depuis la partie de fixation (28) selon la direction axiale (X), et un bourrelet annulaire (30) disposé entre le voile (26) et le moyeu (24), le bourrelet annulaire (30) étant fixé au voile (26) tandis qu'un espace annulaire (32) est ménagé entre le moyeu (24) et le bourrelet annulaire (30). L'invention concerne également une pompe centrifuge comprenant la roue (10) et un procédé de fabrication de la roue (10).The invention relates to an impeller (10) for a centrifugal pump having an axial direction (X), the impeller (10) comprising a hub (24), a web (26) having a shape of revolution comprising a fixing part (28). of the web (26) with the hub (24), the web (26) widening out from the fixing part (28) in the axial direction (X), and an annular bead (30) disposed between the web (26) and the hub (24), the annular bead (30) being fixed to the web (26) while an annular space (32) is formed between the hub (24) and the annular bead (30). The invention also relates to a centrifugal pump comprising the impeller (10) and a method of manufacturing the impeller (10).
