Abstract

In order to diminish the risk of clogging during pumping of, for instance, sewage, the vane (1) is formed with a varying thickness along its length. The speed reduction in the flow channel between the vane inlet and the vane outlet is then limited, since the channel only increases in cross-section by a predetermined limited amount towards the outlet and pressure decreases within the channel are minimised. The vane (1) can be made hollow to decrease balancing problems. <IMAGE>
