Document Type and Number:
Japanese Patent JP2008082316
Kind Code:
A
Abstract:
To provide a pump with an excellent axial balancing system capable of generating bigger axial lifting force.
The pump (10) for sucking a fluid, comprises at least one centrifugal wheel (14) having a fluid inlet edge (48) and a fluid outlet edge (44), and further comprises an axial balancing system (32) comprising a high-pressure flow space (34) defined between a housing and an upstream face (36) of the centrifugal wheel (14).
