An impeller for a vane cell pump includes, but is not limited to vane receptacles for receiving an at least radially movable pump vane. A chamber wall is formed between two adjacent vane receptacles to form a conveying chamber. The chamber wall has an axially projecting web for delimiting a movement of a position ring with respect to the radial movement of the pump vane. The chamber wall includes, but is not limited to a first wall region for secure receiving of the respective pump vane in the vane receptacle. The chamber wall further includes, but is not limited to a second wall region for forming a web thickness d of the web for secure abutment of a sintering tool. In addition, the chamber wall has a third wall region for forming an enlarged conveying chamber volume. As a result, the impeller is easily manufactured and has an enlarged pump capacity for the same installation space.
