Abstract (en)
[origin: EP0733805A1] The wall surface configuration is for a centrifugal pump with an impeller inside a casing, and stator vanes after the impeller shaped to deflect fibres. There are recesses (6) in the region of the stator vane leading edges (5). These recesses form a connection between the spaces on either side of the stator vane (4). The recesses may run lengthwise. They may extend in an angle to the rotation plane of the impeller. There may be a free standing edge (7) of the stator vane in the region of the recesses, which may be asymmetric relative to the stator vane and may have side walls at different angles.
