-Concentricity of seal gland face
-Stuffing box face perpendicularity
-Shaft run-out (check if shaft is straight and round)
-Radial Deflection (condition of bearings and their fit in housing)
-Shaft end-play
Flowserve has a great form available - Centrifugal Pump Repair Data Form (pg. 229-232 of their Seal Specialist 1 course)
If you are having the impeller rebuilt (either buildup with devcon or trimming), you may want to specify criteria for the rebuild. I dont have any data in front of me, but API might have a balancing specification.
Hope this helps!
