摘要： A rotary part being an impeller or expeller for a pump which can be rotated in a forward direction about a rotation axis X-X. The rotary part comprises a shroud having an outer peripheral edge portion and opposed first, and second faces, a plurality of expelling vanes projecting from one or more of the second faces of the shroud, each expelling vane having an inner side and an outer side which is at or near the outer peripheral edge portion of the shroud, the expelling vanes extending in a direction between the rotation axis X-X towards the outer peripheral edge portion of the shroud, each expelling vane further including a leading side facing in the forward direction and having an inner edge and an outer edge, a trailing side facing in a rearward direction and an up per side spaced from the outer face of the shroud. The leading side includes a forwardly inclined section which is inclined forwardly from a radial line Y-Y extending from the rotation axis X-X and which passes through the inner edge of the leading side.
