The invention relates to the pump engineering, in particular to rotors of the centrifugal pumps. The rotor, according to the invention, consists of two disks: drive and driven, coupled between them by blades. The number of blades is determined from the relation:<CHFORM>where Z is the number of the rotor blades; D1 - diameter of the blade inlet edge in the middle part of the rotor meridian section, ? - the blade thickness onto the inlet diameter D1; ?1 - the blade fixation angle onto the inlet diameter D1 into the rotor meridian section.The result of the invention consists in decreasing the mass and the dimensions and in increasing the efficiency of the centrifugal pump.Claims: 3Fig.: 4
