Product Description

Low Noise High Back Pressure Type China Gas High Purity Compressor

A diaphragm compressor is a variant of the classic reciprocating compressor with backup and piston rings and rod seal. The compression of gas occurs by means of a flexible membrane, instead of an intake element. The back and forth moving membrane is driven by a rod and a crankshaft mechanism. Only the membrane and the compressor box come in touch with pumped gas. For this reason this construction is the best suited for pumping toxic and explosive gases. The membrane is reliable enough to take the strain of pumped gas. It must also have adequate chemical properties and sufficient temperature resistance.

Diaphragm compressors are the optimum choice for a variety of important industrial applications requiring clean gas at high pressures. They are ideal for either continuous running or tasks requiring intermittent operation, and can be supplied with flow, temperature and pressure regulation equipment connected to local control rooms. 

Application Areas of Diaphragm Compressor

1.    Hydrogen industry: Compression, storage, and transportation of hydrogen for refueling stations, fuel cell systems, and hydrogen vehicles.

2.    Electronics and semiconductor: Provides high-purity gases (nitrogen, helium, argon) for cleaning, etching, and manufacturing processes.

3.    Chemical and gas industry: Handles corrosive/toxic gases (hydrogen chloride, hydrogen fluoride, hydrogen sulfide) for chemical, petrochemical, and metallurgical industries.

4.    Aerospace and nuclear energy: Supplies and compresses gases in spacecraft and nuclear facilities, ensuring purity and safety under extreme conditions.

5.    Medicine and biopharmaceuticals: Compresses medical gases (oxygen, nitrous oxide) to hospital and laboratory standards for purity and stability.

6.    Environmental protection and gas recovery: Used in gas monitoring, exhaust treatment, and recovery systems for safe processing and reuse of harmful gases.

7.    Scientific research and laboratory: Delivers high purity/high pressure gases for experiments in mass spectrometry, gas chromatography, and more.
