This paper describes the design of an electromagnetic pump for liquid metals. The flow in a flat disk channel of the pump is generated by an electromagnetic force. The electric current passes through the liquid metal via outlet pipes that constitute the secondary winding of a transformer. The channel of the pump is placed in the gap between ferromagnetic C-shaped cores, which significantly enhances the magnetic induction in the interpolar space and in the channel. Numerical studies were performed to find optimal pump design parameters. A procedure to evaluate the level of ferromagnetic core saturation has been developed and tested experimentally. Based on the results of the calculations, a prototype pump with required operating characteristics has been designed and tested in a gallium loop. The computed numerical results are in good agreement with the corresponding experimental data. Figs 9, Refs 11.
