*** USE OPTION (1) TO SELECT PUMP SIZE ***

West System 303 Dispensing Pump Set is designed for convenient and accurate metering of resin and hardeners. For convenience, the pumps mount directly onto the resin and hardener containers, and eliminate the mess involved with measuring by weight or volume.

303 Special Ratio Mini Pumps are calibrated to deliver the working ratio of 3 parts of 105 resin to 1 part of either 207 Special Coating or 209 Super Slow hardeners, with one full pump stroke of resin for each one full pump stroke of hardener.
