Abstract
A diaphragm pump has a magnetic actuator. A permanent magnetic assembly is secured to the outside face of the diaphragm of the pump and provides at least a pair of opposed magnetic pole faces directed away from the diaphragm. An electromagnet assembly has at least a pair of opposite poles located opposite but spaced from the pole faces of the permanent magnet assembly. Energizing the electromagnet with alternating current, alternately repels and attracts the permanent magnet assembly, thereby reciprocating the diaphragm to operate the pump.
