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.

Questions & Answers about WEST System 300 Mini Pump Set:
2013-04-08AL KOLSCH asked: Will this set fit on the 1 Gal Resin and 1Qt hardener cans?
+Expand Answers
2013-04-11JOSEPH M GLEDHILL: Yes, but you should specify or call them. My project was a cedar strip canoe that has been glassed on both sides. I used the 205/207 and I would recommend it. Do not leave the pumps in the cans for extended periods of time as they will clog up as they are hard to get clean. Good quality and a good company. All my dealing with them have been excellent...
2013-04-12MICHAEL LAUER: Yes. Different length straws included for quart/gallon.
2013-04-12ROBERT BROWN: Yes, I bought this set for that purpose and it worked perfectly.
2013-04-12DENNIS DUNN: Yes.
2012-05-26A shopper asked: How do you clean the dispenser pumps?
+Expand Answers
2012-05-30WILL BOUDREAU: The dispenser pumps will clog with hard/gelatious epoxy clumps after a few months of inactivity, thereby completely blocking pumping action. So, unscrew the pump but leave it loosely in the epoxy can, and place the can in a pan of boiling water so the water level comes up 2/3 of the way to the estimated level of the epoxy in the can. Boil for 30 minutes or until the hard clumps have liquified and resorbed into the rest of the epoxy.
If you're referring to drips/spills of uncatalyzed epoxy on the tip of the dispenser and on the top of the epoxy can, an alcohol swab will dissolve it.
2012-05-30WOLFGANG KAINZ: acetone
2012-05-30DONALD COLLINS: There shouldn't be any need to clean the dispenser.
2012-05-30PAUL FISCHER: they do not need to be cleaned
the pumps work fine with using them irregularly
I keep an extra set on hand , just in case , we move them from can to can as we open a new container
2012-05-30JAMES PETERS SNYDER: I never have. The epoxy doesn't harden until you mix it together, and I keep the pumps in the cans until I use it's used up. Even in gallon cans.
I suppose you could soak it in alcohol, but I've never seen a reason to do that.
2012-05-30CRAIG VOGT: I don't they stay in can until the next use. Keep them from being contaminated by other pumps so don't harden at times. Give a little
squirt to have fresh chemicals on your first measured stroke.
Mine have been used this way for a year.
Craig
2012-05-30DOUG BELL: I usually don't clean the pumps because they are in use quite a bit, and there is a lot of material still in the pump body. When I do clean them out, I pump denatured alcohol through the pumps until it runs clear.
2012-05-31JAMES SCHROEDER: You don't.
Just leave them in the appropriate can. If anything, cover the can and pumps with some Saran wrap from the kitchen to keep them from picking up shop dust.
2012-06-09DENNIS DUNN: I never tried to clean the pumps. They work well for a very long time, even with intermittent use. I use a scale to check all my batches, so I don't worry about short shots. When the pumps cease to work, I simply replace them.
2012-04-08A shopper asked: What do you do with the pumps between uses to keep them from getting clogged?
+Expand Answers
2012-04-09PAUL FISCHER: Nothing, we have not had any problems with the Minipumps plugging between uses.
2012-04-09PHILIP STOFANAK: I've had the resin and 205 hardener for years, and I never had a clogging issue with the pumps, with no particular care taken of them.
2012-04-09CRAIG VOGT: Once screwed on to can I leave them there. Store at room temp.
I have never had any clogging. If they have sat a while I do give
A little squirt into a container to make sure they are working ok.
Just a little as epoxy not cheap.
2012-04-09BARRY GOLASH: I keep all the west system items in a plastic 5 gallon pail. This keeps the pumps clean. My woodshop has alot of air bourne dust. If it gets on the pumps it makes the function of the pump work much harder. Sometimes so much so that I think the pump has lost it prime. Its very important not to lose prime. This keeps the ratio in the correct amount.. If the ratio is not correct doors can fall apart. Please don`t ask how I know this fact.
2012-04-09GERALD GORONEA: Hi,
That is a problem i haven't had. I've used This system for more than 12 years, sometimes the pumps sit for several months between use, and they work fine when i need them. Sometimes, if the resin or catalyst is cold it is hard to pump. Warming it a little solves the problem. Don't know if this helps you.
Jerry
2012-04-09KEVIN KENNEY: Nothing. Just keep the hardener pump on the hardener container and the resin pump on the resin container and do not mix them up.
2012-04-09DENNIS DUNN: I have used West System products for quite some time, and the pumps I've used last for a long time without clogging - as much as several months between uses. Occasionally, a pump clogs and I just replace it. I suppose you could clean a pump with solvent, but that's too much hassle for me.
I keep my 105/205 in my garage, which stays at about 55-60 deg F year round. Maybe this helps. I also weigh each batch to make sure of the correct ratio. Pumps that have been sitting for some time can pump short.
2012-04-09CHARLES PUTNAM: I've been using them for many years, and I've never had them clog. Excess material drains back into the can or, more likely, drips out the spout of the pump, making a mess, but they haven't clogged on me.
2012-04-09PETER JENNY: I know exactly what you meen. My pumps, especially the smaller hardener pumps, tend to stick and not pop back up for another accurate discharge after a few months. I have been simply discarding the "sticky" pumps and purchassing new ones when I nolonger trust their accuracy. I too would like to know a good solution to this problem in an otherwise great product..
2012-04-09WOLFGANG KAINZ: Nothing, so far. I am using them now for a few weeks and they do not get clogged. However, I do not know how long you can leave them open.
These pumps make mixing the West System epoxy easier - it probably saves money in the end as there are no bad batches of epoxy. They are accurate, easy to use, and seem to hold up well.

Comments about WEST System 300 Mini Pump Set:
These pumps work great and make epoxy mixing an easy, quick, fool-proof process. Although these pumps are durable, they won't last forever. You don't want to be in the middle of a large project and find yourself with a broken pump - and unable to mix additional epoxy. Keep a spare set - it's good insurance.

Comments about WEST System 300 Mini Pump Set:
The product performs exactly as expected. I need to mix batches from couple of tablespoons to a quart at a time. This allows me to mix exactly what I need at the moment without wasting by mixing too much.
The time savings is substantial as well
Great find and glad I purchased.

Comments about WEST System 300 Mini Pump Set:
These pumps take the guess-work out of mixing epoxy resin. They also allow mixing of large batches of resin for production work. I wouldn't use any epoxy resin product without this type of metering for hardener to resin mixing ratios.
