Brief description of diaphragm compressors

The diaphragm compressor is an excellent choice when you want tight compression of the actuating medium and where the intrusion of impurities into the medium is unacceptable. The actuating medium is not in contact with the piston or piston rings that are typically used to create the offset in traditional compressors. They have no dynamic seals; the contamination with hydraulic oil (which is usually used to seal the piston rings in reciprocating and screw compressors) is entirely excluded, making this type of compressors hermetic. Diaphragm compressors may have horizontal and vertical design and multiple compression stages.

The high purity diaphragm compression is achieved by insulating the pulsating hydraulic fluid from the actuating medium through metal diaphragms and a series of static seals. The reciprocating motion of the piston affects the high-pressure chamber with hydraulic oil through the fixed cavities, which allows the diaphragms to compress and pump the actuating medium. This compressor is a form of the reciprocating-type units, so its mechanism is the same as that of plunger and reciprocating pumps.

Diaphragm compressors can operate at suction pressures starting from the atmospheric pressure and produce discharge pressure up to 60,000 psig.

The unique feature of diaphragm compressors is that the compression, which in another compressor type would require from 3 to 5 stages, can be performed by one or two stages.

Operation principle of the diaphragm compressor - suction and discharge phases

Diaphragm compressors are ideal for compression of all gases without leaks or contamination. Advantages of the gas treatment consist in ultra high purity without leakage. This is what differs diaphragm compressors from reciprocating and screw compressors. Reciprocating and screw machines can have leaks around the piston rings, which leads to the contamination of the process gas with hydraulic oil.

This type of compressors is perfect for the compression of toxic or potentially volatile gases, such as hydrogen, as they are sealed with respect to the environment, giving ultimately a very low degree of leaks within the approximate range of 10-4mbar/s.

The gas is compressed due to the use of vibrating diaphragms of sandwich type driven by hydraulic pressure generated by the piston. Diaphragm compressors can operate at speeds within the range of 250rpm or 720rpm depending on the size. The gas is supplied through the suction valve and compressed in the gas space, and then goes to the exhaust valve. As in most compressors, it is possible to have multiple stages, and the diaphragm compressor can have pressure ratio of 1:20. This makes it possible to achieve the outlet pressure up to about 3,000bar, with the limitation on the allowable temperature at the stage outlet.

Compressors of this type are ideal for all types of laboratory applications, as well as for experimental facilities and industrial applications that require low consumption of the actuating media. These devices can be used for testing and calibration of critical devices, such as components of missile defense systems, where the hydraulic pressure test and calibration are difficult or impossible to carry out. The compressors are suitable for suction at a constant or continuously changing pressure up to the maximum allowable discharge pressure.

Types of the diaphragm compressor drives

Typical applications of diaphragm compressors include:

Industrial gases at fuel filling stations for trailers for the transportation of gas cylinders, or gas distribution applications for such gases as helium, hydrogen, nitrogen, argon, etc.

Specialty gases, including gases for electronics (silane, special gas mixtures), calibration gases, etc.

Alternative energy sectors including the hydrogen energy sector, compressed natural gas and biogas applications.

Diaphragm compressors are used in the food, pharmaceutical, and nuclear industries.

Areas of use:

  • Power plants / gas companies
  • Environmental control (as compressors for gas sampling)
  • This type of compressors is also used to analyze the atmospheric conditions with the high content of CO and CO2, for example in tunnels and on highways
  • Oil refineries
  • Methanol, ethane, ethylene, propane
  • Treatment of freon and PTFE
  • Various freon gases, halon, and fluorine
  • Pilot plants, laboratories
  • Air, neon, xenon, krypton, and He
  • This type of compressors is used in the transfer / filling of gases
  • Equipment for the production of semiconductors. High purity gases (N2, O2, H2, air, etc.) are used in the production process of semiconductors
  • Other applications for СO2, СО, Cl, HCl, H2S, SO3, NH3, etc.

Diaphragm compressors operate with synthetic gases with different composition in the petrochemical equipment for testing, where new additives are developed and tested. It is possible to compress synthetic gases from the low-pressure level at the suction side up to the operating pressure, for example, 200bar.

One of the two-stage diaphragm compressor applications is the compression of hydrogen supplied from the Н2 source up to the wellhead pressure, which is about 100-150bar higher than the respective filling pressure. Depending on the application, the filling pressure can amount to 350bar or 700bar.

For some time now, diaphragm compressors are used for the operation of gases in fuel elements and for the recovery of greenhouse gases.

The diaphragm compressor is also intended to compress atmospheric air for storage or immediate use. The diaphragms can be made of rubber or silicone.

Typical application of compressors with metal diaphragms:

  • Filling of cylinders / storage in settling bowls and under high pressure
  • Treatment of highly corrosive gases, Cl2, HCl, F2, and O2
  • Gases for electronic devices: silane, helium, nitrogen, and hydrogen
  • Radioactive gases: nuclear power plants in Europe are equipped with compressors of this type with metal diaphragms
  • Gas production and purification

Typical application of compressors with teflon diaphragms:

  • Sampling at LNG plants
  • Gas sampling for environmental control measures
  • Freon gas and PTFE treatment
  • СО2, СО, Cl, HCl, H2S, SO3, and NH3

When using these compressors, you should ensure that there are no solid impurities in the compressed medium, which may adversely affect the diaphragm service life.

Diaphragm compressors are used in a wide range of applications: it may be small models with a capacity of 1/8hp capable of producing 50PSI, and industrial gas compressors capable of operating with less constant pressure up to 6000PSI. The diaphragm compressor is particularly suitable for creative applications such as hobbies, for example, aerographics, as well as for the compression of toxic or hazardous gases because the metal on metal friction is minimized.
