A submersible well pump assembly includes a pump driven by a motor. The pump has a number of stages, each stage including a diffuser having an annular diffuser inlet with an annular outer wall. Diffuser passages lead downstream and inward from the diffuser inlet. An impeller has a circumferential outer edge adjacent the outer wall of the diffuser inlet. Notches are formed in the circumferential outer edge, defining a serrated configuration.
