Abstract

A centrifugal pump comprising a housing, a shaft rotatably mounted in a bore of the housing, a wheel fixed to hub secured to the shaft and comprising a plurality of angularly distributed openings, a seal assembly comprising a counter-ring, a friction ring secured to a flexible member and resilient means for urging the ring into contact with the counter-ring, the counter-ring and flexible member being secured to respective connection members, of which one is fitted in a recess of the housing and comprises a radial thrust surface facing said openings of the wheel while the other is fixed to the hub and is made of elastomer material, further comprising a sleeve surrounding the shaft, said sleeve being secured to the hub at one end thereof and being provided at its other end with a radially enlarged abutment portion to retain said one connection member or the respective one of said counter-ring and said flexible member before its mounting inside said housing.
