West System 301 Dosing Pump

WEST SYSTEM 301 Dosing Pump Set for 5:1 Epoxy Ratio

Achieve flawless, professional-grade epoxy bonds with every project by using the WEST SYSTEM 301 Dosing Pump set. An essential tool for boat maintenance, repair, and construction, these mini-pumps are engineered to eliminate the common frustrations and inaccuracies of mixing epoxy by hand. Say goodbye to the guesswork, mess, and potential for error associated with hand metering, and embrace the confidence that comes with perfect, repeatable results.

The cornerstone of the 301 Dosing Pump system is its incredible accuracy. Specifically designed for accurate and convenient metering of WEST SYSTEM´s 105 Resin and the corresponding 205 Fast Hardener or 206 Slow Hardener, this set is your guarantee for a reliable cure and maximum bond strength. The pumps have been meticulously calibrated to deliver the correct 5:1 ratio (five parts resin to one part hardener by weight) with a single, smooth stroke of each pump. This precision ensures that your epoxy mixture has the ideal chemical balance for optimal performance, preventing the weak, brittle, or tacky finishes that result from an incorrect ratio.

Designed for maximum efficiency and a clean workspace, the pumps attach directly to the WEST SYSTEM resin and hardener containers. This secure fit not only prevents spills and drips but also allows for long-term mounting. If you are engaged in continuous or frequent work, you can leave the pumps installed on the containers, ready for immediate use whenever you need them. This feature drastically reduces setup and cleanup time, allowing you to focus on the task at hand, whether it´s a small fiberglass repair or a large-scale boatbuilding project.

Using the 301 Dosing Pumps is remarkably simple. After priming, a single, full pulsation of the resin pump and a single, full pulsation of the hardener pump will yield the perfect amount to get started. Each full stroke dispenses approximately 25 grams of 105 Resin and approximately 5 grams of 205 or 206 Hardener. This consistent dispensing action removes the need for scales, measuring cups, and stir sticks for portioning, streamlining your entire workflow. By dispensing the exact amount of material needed, you also significantly reduce waste, making your valuable WEST SYSTEM epoxy go further.

An indispensable accessory for any mariner, boat builder, or DIY enthusiast working with composites, the WEST SYSTEM 301 Dosing Pump set transforms the critical process of epoxy mixing from a chore into a simple, foolproof step. Invest in precision and convenience to ensure the structural integrity and longevity of all your marine maintenance and cleaning projects
