Abstract
The present invention provides a drain pump for a washing appliance. The pump includes a motor having a drive shaft, a drain pump impeller mounted on the shaft, and a pump casing having a side wall which is co-axial with the motor and the impeller, which is adapted to receive water from a wash chamber. The impeller pumps water from the casing when the motor is rotated in a first direction. The pump includes a disc, the periphery of which is adjacent to the wall of the casing to form a seal against fluid flow up a side of the casing. The disc has a hub portion and blades formed on a surface thereof with a root of each blade radially spaced from a periphery of the hub portion over the full height of the blade to form an unimpeded annular fluid passage between the hub portion and the blades.
