Abstract

Les pompes centrifuges souffrent d'usure du joint annulaire entre la roue (2) et le carter ou revêtement latéral (3), du fait de l'écoulement en retour dans le fluide en retour (9). La présente invention améliore ce problème en ayant le jeu du joint annulaire (10) au moins adjacent à l'entrée (6) de la roue (2) qui est incliné, dans la direction de l'écoulement de fluide principal (7) dans l'entrée de la roue (6), suivant un angle entre 0degré et 60degré par rapport à l'axe de rotation de la roue (2).
