An impeller (2) for a pump is designed as a casting and includes at least one blade (4). The impeller (2), when casting, is molded by way of at least two core parts (14, 16). Partition lines (26, 28) between the at least two core parts (14, 16) are distanced to an end-edge (10) of the at least one blade. The end-edge is at a front in a flow direction (S). |
