RELATED APPLICATIONS [0001] The present invention claims priority to U.S. patent application Ser. No. 10/329,013 filed Dec. 23, 2002, entitled "Electromagnetic Pump" and U.S. Provisional Patent Application Ser. No. 60/414,712 filed Sep. 27, 2002, entitled "Electromagnetic Pump", and U.S. Provisional Patent Application Ser. No. 60/365,002 filed Mar. 13, 2002, entitled "Electromagnetic Pump", the contents of which are herein incorporated by reference. FIELD OF THE INVENTION [0002] The present invention relates to an electromagnetically actuated pump for pumping liquids and gases. BACKGROUND OF THE INVENTION [0003] Electromagnetic pumps are used in many applications to pump small volumes of liquids and gases. Conventional electromagnetic pumps have many disadvantages, including high power requirements, inadequate flow rates, complex and expensive manufacturing processes and bulky designs. Many conventional electromagnetic pumps require high drive voltages to attain adequate fluid delivery rates for many applications. Conventional electromagnetic pumps further require complex, expensive electronics to control the pumping process. Moreover, many electromagnetic pumps are not scalable for different applications. SUMMARY OF THE INVENTION [0004] The present invention provides an improved electromagnetic micropump for pumping small volumes of liquids and gases. The micropump 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. [0005] The electromagnetic micropump of the present invention is scalable, has low power requirements, a simplified manufacturing process, is small in size, lightweight and inexpensive to manufacture.
