More about this item

WEST SYSTEM 306-25 Fiberglass & Repair

The WEST SYSTEM Model Pump A is a precision metering pump system designed to dispense 105 Epoxy Resin and hardeners at the correct 5:1 ratio by volume. This professional-grade pump set eliminates the guesswork and potential errors of manual measuring, ensuring accurate mix ratios every time for reliable epoxy cure and performance.

Accurate 5:1 Metering:

This pump system is calibrated to dispense exactly five parts resin to one part hardener with each stroke, matching the required mix ratio for WEST SYSTEM 105 Resin with 205 or 206 Hardeners. Accurate metering is critical for proper epoxy cure—too much or too little hardener can result in soft, tacky, or brittle cures that compromise strength and durability.

Eliminates Measuring Errors:

Manual measuring with cups and scales introduces opportunities for error, especially in busy shop environments or when working with multiple batches. The Model Pump A delivers consistent, repeatable ratios with simple pump strokes, saving time and eliminating the most common cause of epoxy mixing problems.

Professional Efficiency:

For boatyards, professional builders, and frequent epoxy users, metering pumps dramatically improve workflow efficiency. Simply pump the required number of strokes into your mixing container, stir thoroughly, and you're ready to work—no measuring, no calculations, no waste from incorrect ratios.

Key Benefits:

  • Precise 5:1 Ratio: Calibrated for WEST SYSTEM 105 Resin with 205/206 Hardeners
  • Consistent Results: Eliminates mixing errors for reliable epoxy cure
  • Time Saving: Faster than manual measuring methods
  • Easy to Use: Simple pump strokes deliver accurate ratios
  • Professional Quality: Durable construction for long service life
  • Rebuildable: Can be serviced with rebuild kits for extended use

Compatible With:

  • WEST SYSTEM 105 Epoxy Resin
  • WEST SYSTEM 205 Fast Hardener
  • WEST SYSTEM 206 Slow Hardener

Important Notes:

This pump set is designed specifically for the 5:1 mix ratio. If you're using 207 Special Clear Hardener or 209 Extra Slow Hardener (which require different ratios), you'll need the appropriate pump model for those hardeners. Always verify you're using the correct pump for your hardener choice.

Invest in accurate metering for professional-quality results. The Model Pump A ensures every batch of epoxy is mixed correctly, eliminating the most common source of epoxy problems and delivering consistent, reliable performance.
