The 306-25 Metering Pump reduces mixing time and waste on large projects. Great for metering larger quantities of 105 Resin and 205 Fast or 206 Slow (5:1 ratio) Hardeners. A carrying handle allows you to move the pump where the work is. Reservoirs hold one gallon of resin, one quart of hardener. Dispenses approximately 0.5 fl oz of resin/hardener per pump stroke (about 1 qt per minute).
