Electromagnetic pump and method for manufacturing the same

A method for manufacturing an electromagnetic pump, the method comprising:

• producing a hollow duct that extends from a first duct end to a second duct end, the hollow duct having an inlet portion, a central portion, and an outlet portion;
• producing a core that extends from a first core end to a second core end;
• producing a coil assembly comprising a first set of coil units, a second set of coil units, and a third set of coil units, wherein the first set of coil units, the second set of coil units, and the third set of coil units are operable to generate a time-varying magnetic field;
• producing a stator assembly comprising a plurality of stator units;
• and
• assembling the electromagnetic pump by:
• arranging the first set of coil units about an inlet portion of the hollow duct, the second set of coil units about a central portion of the hollow duct, and the third set of coil units about an outlet portion of the hollow duct;
• arranging the plurality of stator units about the hollow duct to receive a portion of the first set of coil units, the second set of coil units, and the third set of coil units;
• and
• arranging the core inside the hollow duct to form an annular channel between the hollow duct and core for carrying a conductive fluid in response to the time-varying magnetic field.
