The invention relates to an electromagnetic drive pump. The pump comprises a pump body which comprises a magnetic component, a plurality of coil assemblies and a control circuit, wherein a successive time sequence of direct currents going to the different coil assemblies is controlled, so the plurality of coil assemblies can generate an overlaid magnetic field with an opposite magnetic pole corresponding to the magnetic component, and the magnetic component can be moved back and forth in a straight-line route along an external shell body in the overlaid magnetic field. The electromagnetic drive pump provided by the invention is characterized in that electromagnetic force is taken as driving force; the magnetic force is used to drive a target mechanism; and the volume of equipment is reduced. Furthermore, an alternately changed magnetic field generated by the coil assemblies can be controlled; the magnetic component can make reciprocating motion which simulates pulse rules of heart pump blood under effects of the magnetic field; and the electromagnetic drive pump can be applied in the technical field of medical equipment and made into a pulse-type blood pump, so damage caused by continuous pump blood filling of a centrifugal pump to human tissues, visceral organs and the brain can be avoided.
