If required, we will re-machine fits between mating parts to ensure parallelism and perpendicularity. Prior to final assembly, the rotating element is balanced to stringent industry standards on our Schenck balancing machine. Once the pump overhaul is complete, a detailed report is generated showing as found and final dimensions on all critical clearances.
