LOWEST PRICES GUARANTEED

Also  available in a 3:1 Metering Pump Ratio

This pump delivers 2.0 fl oz of resin and hardener per full stroke of the dispensing lever. For use with 105 Epoxy Resin® and 205 Fast Hardener® or 206 Slow Hardener®. The 305 High-Capacity 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. It is designed to accurately dispense WEST SYSTEM resins and hardeners at a 5:1 by volume.

User Manual and Product Guide

Additional Info:

Mixing with Drill Motor Mixers
A variety of motor-driven mixers can be used to thoroughly mix epoxy. They are essentially paint mixers or variation of paint mixers chucked into a variable speed drill. When mixing with a motorized mixer, we recommend the following three-step approach:

  1. Mix for 30 seconds with a drill motor mixer.
  2. Stir by hand with the measuring stick, thoroughly scraping the corners and sides.
  3. Mix for 15 to 30 seconds more to blend completely.

Quality Control
Before mixing that big batch, consider quality control. Resin and hardener must be thoroughly mixed. We all know this, but tend to forget during big projects when we’re pressed for time. This is not the place to look for short-cuts. If you don’t follow certain guidelines, a fancy electric mixer will not make up for it.

TOP TESTIMONIALS

Awesome discounts on fishing reels and GPSs. Plus they have next day shipping. The convenience of online shopping is awesome, especially since it's getting harder to get around in store.
They made sure I got the electronics I needed and all the hardware for the install. They even do repair and installs, so I ended up hiring them for the work I needed done on my Mercury. Awesome experience.

JAMES

Great experience! I Was looking to purchase a head gaskets for my Johnson 150 hp outboard motor. Mike & Ashley researched parts I needed and come to find out they turned me on to my outboard engine used O-Rings to reassemble my head covers and provided me with parts and torque specs! Thanks! 100% positive feedback and Recommend this Family Business if you need Marine Supplies.

SCOTT

Family owned and operated, which is a huge plus for me! I was browsing the website looking at Garmin gps units, their prices are great and competitive! I reached out to them to ask where I might find a hard to find lower unit part I was needing. They had it in stock! If they don’t have something in stock, they will get it asap! 100% recommend and I will buy from them again in the future!

MATT

Mike's marine work for me has always been of the highest quality and pricing is honest and competitive. My background as a mechanical engineer makes me an overly pickie customer; even so I would gladly recommend this group to my friends. Mike, especially is a smart contact for his overall knowledge. He is not, I repeat, is not, a parts replacer but a sensible mechanic. Consequently they have my respect and a future supplier of my Marine and auto needs.

TED
