Rebuild Steps

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.

Testing and Bench Verification

With over a dozen dedicated flow test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our pre-shipment testing verifies proper functionality.
