If it breaks....you need another. If you rebuild the pump and the bearings fit really loose, you need another. If the lip/oil seals leak, you need another.
Usually, if the pump has been in a severe service for a while without rebuilding, you are much better off getting a new shaft. When the impeller is removed in such a pump, the impeller threads are usually ruined (or at least bashed to some extent). Jack
