Rebuild and Testing Process:

Trillium takes great care to ensure each Edwards dry pump repair performs to our stringent internal standards, as well as your requirements. Highlights of the process include:

  • Detailed incoming inspection with photographs taken from numerous angles these are used later in the process to ensure the product is returned to you in the same configuration, including any accessories installed on the pump
  • Complete disassembly, thorough cleaning, and a rigorous inspection process to identify any worn components or parts.
  • Expert assembly by fully trained technicians, done safely with ergonomically designed work stations, and the appropriate material handling equipment.
  • Comprehensive testing to verify base pressure, pumping speed, motor current, pump temperature, and a number of other key performance criteria. Copy of final test report provided.

Special Processes

Edwards Dry Pump Services













The difference between a Trillium dry pump repair and our competitors is in the attention we pay to many of the subassemblies on board.

  • Claw recoating: All Teflon coated parts are stripped and recoated on every rebuild. This work is performed in house, which allows us to tightly control the process and offer the lowest cost.
  • Motor Rebuilding: Motors are rebuilt with new bearings, and undergo extensive testing to ensure electrical safety and adequate water cooling.
  • N2 Purge System: Gas modules are helium leak checked, and all digital flow readings are verified against calibrated analog gauges.
  • Electrics and Sensor Modules: Independent testing of each module prior to installation on the pump ensure proper operation. Trillium maintains board level repair capability, and we can fix nearly any problem with these subsystems.
  • Water Cooling Systems: Thermal Control Valves and other cooling system components are descaled, rebuilt and fully pressure tested hydrostatically.
