Abstract (en)

Improved centrifugal pump of the type comprising a supporting body (10) for a permanent-magnet synchronous motor with an impeller (49) coupled to its rotor (22), and for a volute (48) in which the impeller is accommodated. The body (10) and the volute (48) form a sealed housing which contains the rotor and the impeller in respective chambers, separating them from the stator part of the motor. The rotor (22) is rigidly coupled to a shaft (24) that rotates on sliding bearings (26,29) supported by elastic supports (27) which are locked in the corresponding chamber; one of these supports forms a ring for providing hydraulic sealing between the two chambers of the container. <IMAGE>
