摘要

The pump has a pump housing (20, 30, 32), a pumpwheel (12) to rotate in it and blades (14) round the pumpwheel. Each blade has a base sector running radially from the wheel body (63) and a curved outer sector extending out from the base sector so that it is ahead of the base sector in the direction of rotation of the pumpwheel.
