Aim\ To study the relation between the groove structure of the direct current plane electromagnetic pump and static pressure head as well as its relative efficiency. Methods\ By using mercury as working medium, experiments have been conducted at simulating direct current plane electromagnetic pump. The static pressure head values of various groove structures under the same working parameters are measured. The theoretical value being taken as 100% efficiency, their relative efficiencies were calculated. Results\ Various groove structures result in different static pressure head values under the same working parameters and their relative efficiencies are different. Conclusion\ The groove structure of the electromagnetic pump has a great influence on its static pressure head and its relative efficiency. Several important ways can be used to improve the efficiency of the electromagnetic pump including decreasing the working current loss, optimizing the direction of the electrolines, reducing the inner surface area of the groove and increasing the entrance force.
