Multi-stage centrifugal compressors are a type of mechanical compressor that use centrifugal force to increase the pressure of a gas in multiple stages.

This design allows for higher compression ratios and more efficient operation compared to single-stage compressors.

Key components include the impeller, diffuser, casing, and sometimes an intercooler.

Advantages of multi-stage centrifugal compressors include high compression ratios, efficient operation, continuous operation, low maintenance, and a wide range of applications.

Common applications include the oil and gas industry, chemical industry, refrigeration systems, and power generation.
