ABSTRACT:
An electromagnetic diaphragm pump, the mounts for positioning and mounting the field cores on the housing and the fitting portions for fitting the peripheral portions of the diaphragms are integrally formed with the housing so that the attaching positions of the field cores never shift after they are attached. Screw holes are formed through the mounts for attaching the field cores to make the attaching and fixing of the field cores easier.
