PURPOSE:To make piping and cover gas operation unnecessary and simplify the maintenance and repair of the title electromagnetic pump, by inserting the pump into a liquid metal storage tank. CONSTITUTION:A helical duct 12 is wound spirally around the outer periphery of a cylindrical well 11 having a bottom. A magnetic body 14 is inserted into the well 11 and is rotated by a motor 15 through a rotary shaft. The solenoid pump 10 is inserted into a liquid metal storage tank 20 and the upper part of the well 11 is secured to the peripheral rim of the tank 20. Next, the motor 15 is driven to rotate the rotary magnetic body 14 in the well 11. The rotating direction of the rotary magnetic body 14 in this case coincides with the winding direction of the helical duct 12. Then, a magnetic field, made around the well 11 by the rotation of the magnetic body 14, is moved and liquid enters through an inlet opening 13 at the lower part of the duct 12 by the movement of the magnetic field whereby the liquid ascends spirally through the helical duct 12 and is guided to the outside of the tank, then, is sent into a liquid metal testing device or the like through a pipeline 21.
