IMPELLER ASSEMBLY FOR CENTRIFUGAL PUMP |
摘要 |
An impeller assembly for reducing blockage at the inlet of a centrifugal pump includes an impeller having an inlet side and a bearing hub, wherein the bearing hub extends axially outwardly from the inlet side of the impeller. A conical floating sleeve is mounted on the bearing hub and held in place by a detachable retainer. The mating surfaces of either the bearing or the conical floating sleeve may be coated with a polymer to reduce surface friction. The bearing hub of the impeller may also be bored to receive a drive shaft.
