ABSTRACT:
An air purging circulator is provided with a reservoir on the suction side of an impeller chamber in a circulation pump, to allow circulating water to reduce its velocity, and remove air from the lowest pressure point in the system, the suction side of the circulator, where the least amount of dissolved air is present in the circulating water, so that entrained air in the water is released, and vented from the system. The flanged inlet and outlet apertures of the pump housing are axially aligned, and preferably are located at one end of the pump housing opposite from the motor, to allow convenient installation in retrofit of existing systems. Separation media, such as marbles, wire mesh, or crumpled wire, to further slow the water flow and enhance separation of the air from the water, can be provided in the reservoir.
