A centrifugal pump rotor is proposed with the impeller mounted on the shaft using two nuts of fixed interacting reciprocal conical surfaces. The scientific work relates to the field of pump engineering, namely, to one of the methods of locking the rotor nut used in the design of centrifugal pumps, various self-locking devices of mechanisms and structural elements of fasteners that prevent self-unscrewing. The self-locking nut includes a nut, a solid crown with an inner conical surface interacting with the annular groove of the nut itself and with an annular conical groove on the outer surface and, moreover, on one side of the annular groove of the nut itself with a conical outer surface, and the inner conical surface of solid crown is conjugated with the outer conical surface of the nut itself. The inner conical surfaces of the solid crown are connected to the outer ones – the nut with tension.
