Impellers – why underfile?

Pump manufacturers routinely underfile cast metal impellers. Impeller underfiling is primarily a means of establishing dimensional uniformity at the vane exit tips. Vane-to-vane uniformity, in turn, reduces variation in performance from one pump to the next. Underfiling also "straightens" the vane outer diameter surface or "land".
