West System epoxy resin mini pump sets are specifically designed for convenient and accurate 3:1 ratio dispensing of the epoxy resin and hardener.
Mixing West System epoxy by eye or by weight can be tricky, especially in a busy boatyard or a cramped workshop. Even a slight error in the 3:1 ratio can lead to "hot" mixes that cure too fast or, worse, a "soft cure" that remains sticky forever. The West System 301-3 Mini Pump Set takes the guesswork out of the equation. Designed specifically for the 'A Pack' and 'B Pack' resin and hardener containers, these calibrated pumps ensure the exact chemical balance required for a high-strength, permanent bond every single time.
Forget messy measuring jugs and sticky scales. These pumps are designed for simple, one-handed operation: one full depression of the resin pump plus one full depression of the hardener pump delivers the precise 3:1 ratio automatically.
Prevents Waste: Dispense only what you need, down to the last drop.
Saves Time: Go from setup to mixing in seconds.
Durable Design: Made from high-quality, epoxy-resistant plastic for years of repeated use.
These epoxy mini pumps mount directly on to the resin and hardener containers and have been calibrate to dispense five parts of resin to one part of hardener. When you first install your pumps, "prime" them by pumping a few times into a scrap pot until a steady stream appears. To ensure total accuracy, always use full strokes - push the pump all the way down and let it return all the way up.
This mini pump set is suitable for 105 resin and 207 special clear hardener and 209 extra slow hardener. Do not use these pumps for dispensing West System 205 or 206 epoxy hardeners, for this you will need West System 301-5 5:1 Epoxy Resin Pump Sets.
