Abstract
An apparatus and method for supplying virgin sealer and reclaim sealer to a sealer applicator. A closed loop path including a first fluid flow path is coupled between a source of virgin sealer and the applicator and includes a recirculation path from the applicator back to the source of virgin material. A reclaim sealer supply is coupled to the first fluid flow path. Valves open and close the virgin sealer supply and the reclaim sealer supply to alternately supply virgin sealer or reclaim sealer to the applicator. Whenever the first fluid flow path contains reclaim sealer, a valve blocks flow to the recirculation path to prevent reclaim sealer from being recirculated into the source of virgin sealer.
