In modern gas systems, purity, safety, and high pressure are critical requirements. Diaphragm compressors have become the preferred solution for high-end gas compression due to their oil-free, leak-free, and high-pressure performance.
They are widely used in nitrogen generation systems, hydrogen compression, and oilfield applications.
How a Diaphragm Compressor Works
A diaphragm compressor uses a flexible metal diaphragm driven by a hydraulic system to compress gas.
Working stages:
- Suction
- Compression
- Discharge
- Return
👉 Gas is completely isolated from mechanical parts → 100% oil-free compression
Key Advantages
Oil-Free Compression
Perfect for high-purity gases like nitrogen and hydrogen.
Zero Leakage
Ideal for:
- Toxic gases
- Flammable gases
High Pressure Output
- Standard: 50 MPa
- Custom: up to 100 MPa
Wide Capacity Control
10%–100% adjustable
Low Maintenance
- Long service interval
- Modular design
Long Service Life
- Diaphragm life >5 years
- System life >15 years
Applications
- Nitrogen compression systems
- Oilfield nitrogen injection (EOR)
- Hydrogen energy
- Chemical processing
- Semiconductor gas supply
Integration with Nitrogen Systems (IMPORTANT)
Typical process:
Air → Compression → Nitrogen generation → High-pressure compression → Application
Recommended solutions:
Conclusion
Diaphragm compressors are the ideal solution for:
- Oil-free gas compression
