The Blueprint Process

Comprehensive Examination and Remanufacturing

  • Disassembly and decontamination of the jet assembly and pump body.
  • Certified Vacuum Technicians will clean and inspect the boiler plate, cooling coils, heaters, heater studs, thermostats and all other pump parts for deterioration or damage.
  • If any major damage has occurred to the jet assembly, cooling system, boiler plate or other areas, you will be provided with a final quote upon the completion of the diffusion pump evaluation.
  • Replacement of all consumable parts
  • Inboard and outboard leak detection
  • Pressure testing of the cooling coils
