The Blueprint Process


  • Via state-of-the-art, EPA compliant systems


  • Certified Vacuum Technicians utilizing specially designed and calibrated instruments will thoroughly inspect all of the unit’s components (including electrical and diagnostic systems) vs original OEM specifications.

In-House Machine Shop Service – remanufacturing of major components vs. replacement with new.

  • Demonstrated ability to over-size the hinge bar bore in custom increments up to 0.750” oversize – maximizing pump’s effective life.
  • Custom hinge bar manufacturing to fit new bore dimension
  • Remanufacturing of pistons and eccentrics


  • The standard rebuild of a piston pump will include the replacement of o-rings, gaskets, seals, freeze plugs, keys, valve springs, valve clappers, valve seats, bearings, sight glass, oil flow indicator, ball valves, solenoid valve, and a rebuilt oil separator.

Testing/Quality Control

  • Inboard and Outboard Helium Leak Testing
  • Extensive post re-manufacturing testing via proprietary software/hardware.
  • Applicable equipment software verified and re-set (run hours, etc.).
