FIELD: electricity.
SUBSTANCE: invention relates to an electrical engineering, to MHD-TECHNIQUE, in particular to electromagnetic induction pumps for pumping of pool metals on atomic power plants, in chemical and metallurgical industries. The electromagnetic induction pump includes the thermal screen located between inductor and channel. The pump has an average diameter D, longitudinal axis of the channel, inductor coil with active length, number of pairs of poles p, polar graduations τ. The thermal shield is made as a spiral with k turns, the split line of which an angle of inclination to the longitudinal axis of the channel, where k - positive integer value.
EFFECT: improvement of efficiency and operational life.
