diaphragm compressors for aerospace and nuclear power

Our diaphragm compressors are designed for high purity gas compression (up to 99.999%), making them the preferred choice for handling rare, hazardous, and toxic gases. With advanced isolation and sealing technologies, these compressors guarantee the highest safety and purity in demanding applications.

Features of Diaphragm Compressors

1. High purity compression: Gas never contacts lubricating oil, ensuring ultra-high purity—ideal for hydrogen, oxygen, helium, and other specialty gases.
2. Strong sealing: Diaphragm and precision sealing technology fully isolate gas from the mechanical system, eliminating leakage risks common in traditional compressors.
3. Large compression ratio: Handles a wide range of gases, providing low to high pressure output—especially suited for high-pressure applications.
4. Wide adaptability: Configurations available for single to three-stage compression, covering various pressure levels and industry needs.
5. High safety: Suitable for flammable, toxic, corrosive, or radioactive gases, ensuring secure and safe operation.
6. High efficiency and stability: Advanced cooling systems maintain optimal temperature during compression, improving equipment reliability and service life.

Working Principle of Diaphragm Compressors

The diaphragm compressor uses a reciprocating diaphragm to compress gas, providing complete isolation between the gas and mechanical drive components:

1. Diaphragm drive: A hydraulic or mechanical system pushes the diaphragm to move reciprocally, compressing the gas within the chamber.
2. Gas intake and discharge: During diaphragm movement, gas is drawn in through the suction valve, compressed, and discharged via the exhaust valve.
3. Multi-stage compression: For high pressure, multiple stages gradually increase gas pressure for stable, efficient compression.
4. Gas isolation: Complete separation of gas and mechanical system preserves gas purity and prevents contamination or lubricant leakage.
5. Cooling system: Integrated cooling dissipates heat generated during compression, ensuring reliable long-term operation.

Application Areas of Diaphragm Compressors

1. Hydrogen industry: Pressurization, storage, and delivery for hydrogen fueling stations and fuel cell systems.
2. Electronics & semiconductor industry: Compression of high-purity nitrogen, helium, silane, and other specialty gases for precise manufacturing processes.
3. Fluorine chemical & chemical industry: Safe compression of corrosive gases (e.g., hydrogen fluoride, hydrogen chloride) used in chemical production.
4. Petrochemical industry: Compression and transportation of hydrogen, hydrogen sulfide, and other gases in refining and natural gas processing.
5. Metallurgical industry: Provides high-purity nitrogen, argon, and other protective gases for welding, surface treatment, and other processes.
6. Aerospace & nuclear power: Critical gas supply for spacecraft, nuclear plants, and other high-reliability applications.
7. Pharmaceutical & medical: Compression of high-purity medical gases (oxygen, nitrous oxide) for healthcare and research.
8. Scientific research: High-purity gas compression for laboratories, including mass spectrometry and gas chromatography.
9. Environmental protection: Efficient, safe exhaust gas treatment and gas recovery solutions.
