Dry vacuum pumps (oil-free vacuum pumps) are widely used in leak detection applications that demand high cleanliness, corrosion resistance, and operational efficiency due to their oil-free operation, corrosion resistance, and simple maintenance requirements. The following outlines typical industries and components where dry pumps are essential for leak testing:
1. Semiconductor and Electronics Industry

  • Leak testing components:
  • Wafer fabrication equipment (e.g., etching machines, CVD reaction chambers)
  • High-vacuum sealed devices (MEMS sensors, chip packaging)

Vacuum coating equipment
2. New Energy Industry (Lithium Batteries/Hydrogen Energy)

  • Leak testing components:
  • Lithium battery electrolyte filling chambers
  • Fuel cell bipolar plates/stack sealing
  • Hydrogen storage tank valves and pipelines

3. Medical and Pharmaceutical Industry

  • Leak testing components:
  • Sterile packaging (vials, prefilled syringes)
  • Vacuum freeze dryers (lyophilizers)
  • Medical catheters/implant device packaging

4. Automotive Industry

  • Leak testing components:
  • New energy vehicle battery pack sealing
  • High-pressure fuel system pipelines (for hydrogen fuel cell vehicles)

5. Scientific Research and High-End Manufacturing

  • Leak testing components:
  • Particle accelerator vacuum pipelines
  • Spacecraft fuel tanks (satellites, rockets)
  • Superconducting equipment cooling systems
