Abstract

An ejector pump for the transport of materials or mixtures of materials capable of flowing with the aid of a fluid driving medium is provided. The ejector pump includes at least one flow management profile which is placed in the flow channel of the ejector pump and which displaces the fluid that is flowing against the profile in a lateral direction component away from the original direction of flow. Therefore, the fluid in the middle of the flow channel makes its way closer to one of the flow channel walls thus limiting the areas of turbulence that occur during the mixing of material that is to be transported with the driving medium.
