Title (EN) CENTRIFUGAL PUMP WITH OFFSET VOLUTE
(FR) POMPE CENTRIFUGE À VOLUTE DÉCALÉE
Abstract:
(EN) A pump includes: (a) an elongated pump housing having first and second ends: (b) a primary impeller mounted in the housing for rotation about an axis, the impeller comprising a plurality of vanes whose outer tips define an impeller plane; (c) an inlet disposed in fluid communication with the primary impeller; and (d) an annular volute housing communicating with the primary impeller and with an outlet, where the volute housing is axially offset from the impeller plane.
(FR) L'invention concerne une pompe comprenant : (a) un carter allongé de pompe possédant une première extrémité et une seconde extrémité ; (b) une roue principale montée dans le carter pouvant tourner autour d'un axe, la roue comprenant une pluralité d'aubes dont les extrémités externes définissent un plan de roue ; (c) un orifice de sortie placé en communication de fluide avec la roue principale ; et (d) un carter de volute annulaire communiquant avec la roue primaire et avec un orifice de sortie, le carter de volute étant décalé axialement par rapport au plan de la roue.
