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
