ABSTRACT:
A pump is provided in which the fluid being pumped is used to lubricate the moving parts of the pump and the flow path of the fluid through the pump insures that at least a portion of the fluid circulates around the moving parts of the pump to assure efficient lubrication and rapid flushing of the pump. The pump is driven by a pair of concentric magnets, the interior magnet being sealed off relative to the outer magnet.
