WEST System 300 Mini Pump Set

300 Mini Pumps provide accurate metering of all Group Size A, B and C West System epoxy resin and hardeners. They mount directly on resin and hardener containers and eliminate the messes associated with measuring by weight or volume.

Calibrated to deliver the proper working ratio, the West 300 Mini Pump Set includes one resin pump and two hardener pumps. As packaged, the pumps are ready to install on Group Size B containers. A package of extension tubes for the smaller Group Size A containers are included with the set. Group Size C extension tubes are included in the 105C Resin and in the 207-SC or 209-SC packages.

If necessary, you can combine different group sized-as long as all of the pumps have a yellow head. To avoid confusion and possible off-ratio metering, 300 Mini Pumps have yellow heads, which should not be used in with any older pumps with a white head (301 and 303 pumps).

Essential for West System Mixing


These pumps work beautifully to provide just the right mixture of epoxy and hardener for small to medium size jobs. I blend these together in disposable plastic liners normally used for paint.

great for large projects: cleaning seems impossible


These are perfrt for large projects where you are hitting he pmps almost daily. But the pumps clof up with time unused. Tried soaking in acetone and pumping it through,. Not effective.

Works Perfectly

Works really well


The only thing I wish, was it told me that I would need 4 cans of hardener to use 1 gallon of Resin. Had 3/4 of the camper done and had to wait until I ordered more hardener to finish the project.




Rockin chair not a rocking boat


Used to glue up a Maloof rocking chair. I'm an impressed fine wood worker.

great tool


I have used these pumps on B sized 105/205 epoxy and they measure perfectly every time, with just a bit of attention to detail - I have received maybe one or two pumps that come loose or strip out after a few uses but these in my eyes were just lemons - I've been using these rigorously for a few years now and they perform well just about every time. no guessing, just pump and mix. I always have extra sets in stock just in case.



Worthwhile investment


For large quantities I measure the 5:1 in 6 equal sized containers but by far I mostly mix patches that are smaller. I wouldn't be without the pumps and just purchased this new set because my pumps were several years old. Once installed on the container, I leave them on permanently, year-round.

Nice convenient and easy


Easy to mix epoxy in small batches. Saves rushing to apply before it epoxy sets up

West epoxy and mini pumps


The West System metering pumps are great, especially when you're working with small, multiple batches.

Typical quality from WEST System folks.


I use these pumps for both WEST System epoxy and RAKA 5:1 Epoxy/Hardeners for my boat building project - a large Constant Camber sailboat. At this point in time, I am just coating and building small parts and subassemblies. In the future, when I start laying up panels and glassing large surfaces, I plan of purchasing a WEST System Lever Pump. Even with a lever Pump on hand, The Mini Pumps will still be useful for small batches of epoxy when working inside the boat without having to drag the whole lever pump on its cart inside. While sometimes considered a bit "pricey" - WEST System products are all of excellent quality. As the old saw goes, you usually get what you pay for, and the WEST System pumps are accurate, sturdy and will last the length of the project. I tried to go "cheap" in the beginning, but the economy pumps offered by other suppliers did not hold up and were not accurate enough to get consistent mixes. The bottom line is If you use WEST Epoxy, use their pumps - you will not go wrong. The extra couple of dollars spent will save lots of headaches. In addition, since I am also using RAKA Epoxy that has a 5:1 ratio, the WEST System pumps work great and are superior to those offered by RAKA.
