Abstract
A pump wheel for a pump has a base body that can be rotated about a rotational axis and on which at least one wing element is arranged for conveying a fluid during the rotation of the pump wheel. The pump wheel has a pivoting device by which the at least one wing element is mounted in such a way that it can pivot about a pivoting axis arranged at an angle larger than zero degrees in relation to the rotational axis of the pump wheel, according to a rotational direction, between an action position in which a conveyor pressure for the fluid can be generated, and an idle position in which there is essentially no conveyor pressure.
