DOUBLE DIAPHRAGM PUMPS WITH AN ELECTROMAGNETIC DRIVE

A double diaphragm pump has an electromagnetic drive mechanism in which an electromagnetic coil is located between two permanents magnets of like polarity that are alternately attracted to the electromagnetic coil as the polarity of the electromagnetic coil changes. The electromagnetic coil and the...

Beschreibung
Zusammenfassung:	A double diaphragm pump has an electromagnetic drive mechanism in which an electromagnetic coil is located between two permanents magnets of like polarity that are alternately attracted to the electromagnetic coil as the polarity of the electromagnetic coil changes. The electromagnetic coil and the permanent magnets are located within a piston assembly that is caused to reciprocate via the change in polarity of the electromagnetic coil. In a second embodiment, there are a plurality of electromagnetic coils arranged in two adjacent rows that surround a shaft with a set of a plurality of permanent magnets located between each pair of electromagnetic coils.
