A centrifugal liquid purifier comprising a vertically extending hollow axle secured on a base and having an inlet and an outlet for liquid, both the inlet and the outlet communicate with respective spaces of a cylindrical rotor mounted on the axle. The casing of the rotor accommodates a bushing arranged coaxially with the hollow axle and is provided with a spiral-shaped band fixed thereon; and with spacers located one after another between adjacent turns of the band in parallel with the hollow axle. The spacers form radial rows and together with the band define slit passages for liquid. The band is made with crimps which run parallel with the hollow axle, while the spacers are located in the crimp tops.
