The main working components of a diaphragm compressor are isolated from the compressed medium, reducing corrosion and wear of mechanical parts, thus resulting in relatively low maintenance costs. The equipment operates smoothly with low noise. Thanks to its structural design and leak-free characteristics, the equipment has good reliability and a low failure rate.

Hydraulically driven diaphragm compressors can have a discharge capacity of thousands of standard cubic meters per hour (Nm³/h), while mechanically driven types are more suitable for smaller discharge applications. The extremely high airtightness and high operating pressure of metal diaphragm compressors make them suitable for compressing and transporting gases in military and civilian nuclear energy technology, chemical industry, and petrochemical industry. They are particularly suitable for compressing highly toxic, corrosive, radioactive, rare, extremely pure, extremely dry, and flammable and explosive gases-a special function not possessed by other types of positive displacement or dynamic compressors.
