West System 3:1 Ratio Positive Displacement Pump 303

This positive displacement pump operates simultaneously by a single lever dispensing resin and hardener per full stroke.

This Positive Displacement Pump dispenses three parts resin and one part hardener (3:1) by volume. It consists of two separate parallel pump systems, one for the resin and one for the hardener. The pump delivers 65ml of resin and hardener per full stroke of the dispensing lever. The reservoirs hold two gallons of resin and one gallon of hardener.

For use with 105 Epoxy Resin and 207 Special Clear Hardener or 209 Extra Slow Hardener.The 303 Positive Displacement Pump is robust and dispenses epoxy faster than any pump we’ve ever offered. It works by trapping a fixed amount of resin and hardener and then forcing (displacing) that trapped volume into the discharge pipe or system. This offers improved epoxy pumping performance because changes in viscosity due to temperature change are no longer an issue. The reservoirs hold two gallons of resin and one gallon of hardener.
