Calibrated to deliver the proper working ratio, the West 300 Mini Pump Set includes one resin pump and two hardener pumps. As packaged, the pumps are ready to install on Group Size B containers. A package of extension tubes for the smaller Group Size A containers are included with the set. Group Size C extension tubes are included in the 105C Resin and in the 207-SC or 209-SC packages.
300 Mini Pumps provide accurate metering of all Group Size A, B and C West System epoxy resin and hardeners. They mount directly on resin and hardener containers and eliminate the messes associated with measuring by weight or volume.
