Abstract: A centrifugal compressor for high pressure (10) with improved efficiency, of the type comprising a rotor (12), an inner case (14), diffusers (16) and diaphragms (18), wherein the surfaces which are subjected to passage of the flow of gas have been subjected to burnishing working.

Abstract: A sealing system (10) which ensures the safe operation of very high pressure centrifugal compressors which process lethal gases. The system comprises sealing means (18, 19) separated by an annular chamber (12), and a discharge line (32) for collecting and eliminating any gases that may be released.
