PURPOSE: An electromagnetic reciprocating pump is provided to improve pumping performance and to freely control pressure and capacity. CONSTITUTION: Permanent magnets(2) reciprocate using interaction between an electromagnet part(11) comprising a plurality of iron cores and the permanent magnets to reciprocate pistons(5) connected with the permanent magnets. Magnetic surfaces of the electromagnet part is formed in trapezoid shape to maximize area contacting with magnetic surfaces of the permanent magnets so as to maximize interaction between the electromagnetic part and the permanent magnets. Power loss is minimized and structure of the pump is simplified thereby.
