The centrifugal pump has a box casing consisting of a first chamber (11) containing the mounting for a permanent magnet synchronous motor.A second chamber (14) contains the rotor (15) of the motor, and a pump wheel fixed to the rotor and in a spiral casing (23).The spiral casing is hydraulically connected to the input (31) and output (37) apertures of the box casing. The input and output apertures are directed towards the axis of the rotor and may be opposite each other relative to the rotor
