Abstract
An impeller for a pump for conveying wastewater is proposed, includes a shroud to be rotated about an axis of rotation defining an axial direction, and a blade to convey the wastewater. The blade includes a leading edge, a trailing edge, a pressure side, a suction side and an upper rim. The blade extends from the shroud in the axial direction to the upper rim and extends in a circumferential direction from the leading edge to the trailing edge. The suction side is the radially inner surface of the blade and the pressure side is the radially outer surface of the blade. The blade includes a closed passage extending inside the blade. The passage has an inlet at the pressure side and an outlet at the suction side of the blade.
