    摘要： Pump (1) comprising a rotary shaft (30), a bearing housing (80) that is fixed relative to the rotary shaft, at least one rolling bearing (70) the inner ring (71) of which is connected to the said rotary shaft and the outer ring (76) of which is able to slide in this housing along the axis of rotation of the rotary shaft. The bearing housing (80) comprises a shoulder (81) situated on one side of this bearing and able rigidly to prevent translational movement of the outer ring (76) along the axis of rotation, and a deformable elastic device (100) fixed to the housing on the other side of the bearing (70) so that the bearing lies between the shoulder and the elastic device.

    摘要： The invention relates to a centrifugal pump. The pump (10) comprises an impeller (20) and a casing (50) surrounding the impeller, the impeller having a main passage (24) that divides into a first passage (241) and a second passage (242) with a common feed inlet (22) parallel to the axis of rotation (A) of the pump, the common feed inlet (22) being the inlet of the main passage (24), the first passage (241) having a first outlet (243) that is radially oriented, opening out at a first diameter relative to the axis of rotation (A) and suitable for supplying fluid at a first pressure, and the second passage (242) having a second outlet (244) that is oriented radially and situated behind the first outlet (243), opening out at a second diameter that is greater than the first diameter, the second outlet (244) being suitable for supplying the fluid at a second pressure that is higher than the first pressure, the impeller (20) co-operating with the casing (50) to form an axial balancing system having a chamber (90) formed between the rear face (27) of the impeller and the portion (57) of the casing that faces the rear face (27), the inlet to the chamber (90) being situated at the level of the second outlet (244).
