Title: FLEXIBLE BEARING RETAINER FOR MULTISTAGE CENTRIFUGAL PUMP
Abstract:
The present invention relates to a centrifugal pump and a bearing retainer for the centrifugal pump. The centrifugal pump has a shaft, a bearing for supporting the shaft, and a bearing retainer for the bearing. The bearing retainer comprises a ring section adapted to surround the bearing and an elastic section adjacent the ring section, wherein the elastic section comprises multiple slits, dividing the elastic section into multiple resilient parts, wherein the multiple resilient parts are adapted to receiving and supporting the bearing, thereby creating a compression force in radial direction perpendicular to the axis of the shaft, allowing the bearing retainer to hold the bearing in a fixed position with respect to the bearing retainer.
