Great pumps, giving the proper mixture for a good use, over and over, even many days in between use. A great time saver without the mess of measuring.

These pumps are an accurate and clever way to achieve the proper ratio of resin to hardener. They always work, even when left in the resin or hardener for several months without use.

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.

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

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.

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.

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

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.

Perfect pumps for the perfect ration of resin-hardener.
