FIELD: manufacturing technology.
SUBSTANCE: in order to reduce erosion of impeller (120, 130) due to liquid droplets in an incoming flow of gas, impeller (120, 130) comprises converging-diverging bottlenecks, wherein the incoming flow passes through the bottlenecks so that the speed of the gas at inlet (122) of the impeller first suddenly and substantially increases and then suddenly and substantially decreases, wherein the impeller is configured so that, internally after its inlet, the incoming flow is deviated gradually in the meridional plane.
EFFECT: fluid tolerant impeller for centrifugal compressors is disclosed.
