Abstract
A pump assembly for a chilled beverage dispenser includes an axle oriented in a substantially vertical orientation at a predetermined location along a bottom wall surface of the dispenser bowl; an impeller which rotates about an axis defined by the axle; an inner pump shell that fits over the axle and defines an internal cavity for enclosing the impeller without impeding rotation of the impeller; and an outer pump shell that fits over and engages the lower pump shell, with a cavity being defined and maintained between the inner pump shell and the outer pump shell. As the bladed impeller rotates, beverage is drawn into the pump assembly along the bottom wall surface of the dispenser bowl, and is also discharged along the bottom wall surface of the dispenser bowl, thus providing maximum agitation of the beverage.
