For use with 205 or 206 (5:1 ratio) Hardeners. Designed and built by Gougeon Brothers for large projects and manufacturing operations. Efficient, high-volume pump. With continuous rotation of the crank, the metered resin and hardener can be delivered at up to five quarts per minute. Positive shutoff prevents resin and hardener loss through dripping spouts. Reservoirs hold two gallons of resin, one gallon of hardener.
