Abstract

An electromagnetic micropump for pumping small volumes of liquids and gases comprises a magnetic actuator assembly, a flexible membrane and a housing defining a chamber and a plurality of valves. The magnetic actuator assembly comprises a coil and a permanent magnet for deflecting the membrane to effect pumping of the fluid. A plurality of micropumps may be stacked together to increase pumping capacity.
