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).

Use the epoxy for furniture repairs. The pumps make it easy to get the correct amount of epoxy and hardener. Better and faster.

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 are great! Unfortunately they are also an indispensable part of the epoxy system they work with. In the past I have purchased West Systems by the gallon and had the pumps included with no additional maneuvering. Not so at Jamestown and they neglected to suggest the inclusion of the pumps with the original order so I had to pay another ten bucks shipping in order tho use the product. It's the little things that count boys. Like I said Pretty good, But you could do bettah

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.

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.

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.
