PUMP COMPRISING AN AXIAL BALANCING SYSTEM

PUMP COMPRISING AN AXIAL BALANCING SYSTEM

The present description relates to a pump (11) or compressor for the flow of a fluid, comprising a casing (13), a centrifugal impeller (15), configured to be rotationally driven with respect to the casing (13) about a main axis defining an axial direction (DA), a restrictive fluid-flow passage forme...

description The present description relates to a pump (11) or compressor for the flow of a fluid, comprising a casing (13), a centrifugal impeller (15), configured to be rotationally driven with respect to the casing (13) about a main axis defining an axial direction (DA), a restrictive fluid-flow passage formed between the casing (13) and the centrifugal impeller (15) defining an axial balancing system (19), the casing (13) comprising a first balancing portion (23) and the centrifugal impeller (15) comprising a second balancing portion (29), the first and second balancing portions (23, 29) defining the inlet of the restrictive flow passage, the second balancing portion (29) of the centrifugal impeller (15) being configured to pass from a rest position, in which the external diameter of the second balancing portion (29) is less than the internal diameter of the first balancing portion (23), to an operating position in which the first and second balancing portions (23, 29) overlap in the axial direction (DA), under the effect of the centrifugal force applied to the rotating centrifugal impeller (15).
