Abstract

L'invention concerne une pièce latérale de pompe à utiliser avec une roue fermée de pompe, laquelle pièce comprend une face arrière de section de paroi latérale comprenant une zone extérieure pourvue d'un bord extérieur dans un plan sensiblement à angle droit avec l'axe de rotation, une zone intérieure pourvue d'un bord intérieur et une zone intermédiaire entre les zones extérieure et intérieure qui est inclinée vers l'intérieur à partir dudit plan, en direction de la section d'entrée, la zone intérieure s'étendant à partir de la zone intermédiaire dans une direction éloignée de la face avant de la section de paroi latérale. La face extérieure du flasque avant de roue et la face arrière de la pièce latérale sont disposées pour se faire face avec un interstice entre elles, la face arrière étant conçue de sorte que la dimension transversale de l'interstice augmente en direction de l'axe de rotation de la roue dans la zone intermédiaire.
