West 303D 3:1 Ratio Dispensing Pumps – 26.7ltr

  • Description


303 Special Ratio West System® 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.

Pumps may be left on the containers during storage. Store resin and hardener in a dry location at room temperature. Keep containers upright to prevent leaks. After a long storage, pumps may need to be re-primed.

Pumps should not need cleaning during regular use. When cleaning is necessary, remove pumps from containers and dry as much as possible. Use a mix of 2 parts methylated spirits and 1 part white vinegar to clean the resin pump. Hot water can be used for cleaning the hardener pump. Shake the pumps thoroughly to remove most liquid and allow to completely dry before reusing.

303 Special Ratio West System® Mini Pumps are 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.
