Repair Process

Every DUPLOMATIC DZCE5G-140/11N/E0K11/B gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.

Diagnostic Testing

With thirteen in-house 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 performance testing verifies proper functionality.

Performance Data
