ABSTRACT:
A completely sealed magnetically driven pump having a piston armature driven by electrical windings. Unique electrical driving circuits are provided for the pump embodying feedback windings magnetically coupled with the driving windings of the pump for controlling the reciprocation. The drive circuits are such as to facilitate driving rates, embodying particularly solid state bistable flip-flop components adaptable to be embodied in or associated with computers or other low power logic devices.
