摘要

The pump (1) has a bearing case (80) fixed with respect to a rotating shaft (30). A lower bearing (70) has an inner ring connected to the shaft and outer ring sliding in the bearing case along a rotating axis of the shaft. The bearing case has a shoulder located on a side of the bearing and rigidly blocking the outer ring along the rotating axis. A deformable elastic device (100) is fixed to the bearing case on another side of the bearing such that the bearing is located between the shoulder and the elastic device.
