摘要： A compressor or pump stage is provided. The compressor or pump stage at least comprising a central shaft and at least one rotor, wherein an axis of rotation of the at least one rotor is the central shaft, wherein at least two axial thrust bearings are arranged axially remote from each other and being associated with each of the at least one rotor and at least two radial bearings arranged between the at least two axial thrust bearings and the at least one rotor comprises a number, n, of rows of impellers arranged at an outer perimeter of the at least one rotor with an axial distance between neighbouring rows of impellers, where n={2, 3, 4 . . . }
