Abstract

An impeller for a pump used for pumping liquid substances, such as waste water, said impeller containing at least one flow channel (2) of a spatially curved shape, wherein the flow channel is of an evenly curved shape and, in the final portion of the channel, the flow channel (2) meets itself, or another channel if the impeller has more than one flow channel. By using the impeller of the invention, a very high efficiency is achieved. <IMAGE>
