301 metering pumps - Yellow - 25kg - West System

Designed for accurate and convenient metering of West System's 105 Resin and 205 or 206 Hardener. Mini - pumps ensure accurate metering of the resin/hardener mixture and eliminate the problems associated with hand metering.The pumps attach directly to the resin and hardener containers and have been calibrated to deliver the correct ratio of five parts resin, by weight, to one part hardener, by weight (5:1), with a single stroke of each pump. When the resin and hardener are in continuous use, the pumps can remain mounted on the containers.A full pulsation of each pump will yield approximately 25 grams of resin and approximately 5 grams of hardener.Warning:Do not use with 207 y209 hardeners.
