In general, centrifugal pumps in the underground water by the rotation of the motor of the motor pump may be used in ground water wells. In this paper, by supplying power to the electromagnet of the upper and lower double-acting water pumps and to study the effects of using force and repulsion. Small underground water wells and boreholes (NX standard (76mm)) in diameter 45㎜ water pumps through performance tests for personnel and repulsive forces between the small water pumps that can be used to develop an electromagnet and a permanent magnet for the pressure to 10bar and flow 4L/min derived for the performance.
