FIELD: non-displacement compressors and pumps.
SUBSTANCE: multi-sectional centrifugal compressor (1) contains at least first and second sections (2, 3), each of these sections (2, 3) containing inlet duct (7, 8) and exhaust duct (9, 10). Outlet duct (9) of first section (2) is located with the possibility of flow communication with inlet duct (8) of second section (3). Second section (3) is configured to compress the fluid compressed by first section (2). Outlet duct (10) of second section (3) is located adjacent to inlet duct (7) of first section (2).
EFFECT: such compressors can be used to compress carbon dioxide.
