Diaphragm compressor is a special structure positive displacement compressor. The cylinder does not need to be lubricated, the sealing performance is good, the compression medium does not contact any lubricant, there is no pollution, and the compression purity can reach 99.999%. It is especially suitable for the compression, transportation, and bottling of high-value rare gases and highly corrosive, toxic, explosive, and radioactive gases. For example, H2、He、Ar、C2H4、F、HS、CL、SiH4、NF

Diaphragm compressor cylinder has good heat dissipation, simple and efficient structure, high pressure can be achieved by two-stage compression, and at the same time, it can be close to isothermal compression. Therefore, it is used in industrial gas, food and medicine, petrochemical industry, aviation nuclear power, military equipment, scientific research, and testing, etc. The field is widely used.


Good sealing performance:
Diaphragm compressor is a special structure positive displacement compressor. The gas does not need lubrication and has good sealing performance. The compressed medium does not come into contact with any lubricant and does not produce any pollution during the compression process. It is especially suitable for high purity (99.9999 % or more), compression, transportation, and filling of precious and rare, extremely corrosive, toxic and harmful, flammable and explosive, and radioactive gases.

The cylinder has good heat dissipation performance:
The working cylinder of the diaphragm compressor has good heat dissipation performance and is close to isothermal compression. It can use a higher compression ratio and is suitable for compressing high-pressure gas.

Technical advantages

  1. The diaphragm compressor has low rotation speed and extends the service life of wearing parts. The new membrane cavity curve improves the volumetric efficiency of the compressor and optimizes the valve adjustment. The diaphragm adopts a special heat treatment method, which greatly improves the service life.
  2. The use of a high-efficiency cooler ensures low temperature and high efficiency of the entire machine, which can appropriately extend the life of lubricating oil, O-rings, and valve springs. Under the condition that the process parameters are met, the structure is more advanced, reasonable and energy-saving.
  3. The membrane head is sealed with inlaid double O-rings, and its sealing effect is far better than that of the open membrane head.
  4. The diaphragm rupture alarm structure is advanced, reasonable and reliable. The diaphragm has no direction when installed and is easy to replace.
