Abstract
Pumping action is performed by a unitary, sealed, easily replaceable pumping element, comprising a housing with a longitudinal axis, a pumping chamber at one end of the housing, an outlet in a wall of the pumping chamber, an inlet in the housing, axially spaced from the pumping chamber, and a circulator in the pumping chamber, mounted on a support which is free of the rotating elements, and which provides freedom of motion for the circulator to revolve in an orbital path about the longitudinal axis. Magnetic means external to the housing drive the circulator in its orbital path by magnetic action through the walls of the housing. The orbital circulator contains a magnetic element and is driven in a circular path by an external rotating magnetic field.
