The utility model discloses an electromagnetic pump. The electromagnetic pump comprises a flexible pump body and at least one compression device; the flexible pump body is provided with an outer wall made of flexible materials, a containing cavity is formed by the outer wall, a liquid inlet and a liquid outlet which are communicated with the containing cavity are further formed in the outer wall, and a liquid inlet one-way valve and a liquid outlet one-way valve are arranged at the liquid inlet and the liquid outlet respectively. The compression device is provided with a guide rail, a sliding block capable of sliding on the guide rail, a first magnet fixedly connected with the sliding block and a second magnet used for driving the first magnet and the sliding block to slide along the guide rail, the flexible pump body is located on a sliding stroke of the sliding block, and magnetic poles of the first magnet or the second magnet are variable. Compared with the prior art, the structure principle different from that of an existing electromagnetic pump is adopted in the electromagnetic pump, and the design development of the electromagnetic pump is enriched; in addition, the electromagnetic pump further has the advantages of being low in cost, easy to replace and long in service life.
