Proper use of the MSR Pump
Ben.Zef
13 years ago
I love reading the complaints, and not to be disparaging, sometimes I find them humorous. Whenever I do read about one of the MSR pumps failing, it's easy to read between the lines and see in all probability what went wrong. To avoid field problems with these sorts of pumps, simple steps must be taken to ensure their reliability. Follow these steps, and you will find your outdoor experience to be always enjoyable. First and foremost, lubricate the pump body frequently by coating with either Vaseline, mineral oil or even wd40. Since fuels have corrosive characteristics, They will leach the resin (over a short period of time) out of the co polymer compound causing embrittlement and slight warping of the body itself. You need not worry about introducing effluent into the fuel source since the ppm (parts per million) is so insignificant as to be not worth worrying about. Next understand that any rubber o ring used in the construct of the pump requires changing annually. Once more the reason is corrosion and degradation of the o - ring compound. Replacing annually will eliminate the leakage problem. Next MSR instruction(s) performs a disservice to the instruction reader: When the pump is not in use, Release the compressed air in the fuel canister since the back pressure serves to destroy over time the pump. Especially when the canister and pump are subjected to elevation changes. Going up into the mountains Once you have released the air pressure, open the valve to allow the trapped fuel within the chamber of the pump to flow back into the canister. This is simply done by holding the pump upwards above the fuel line within the canister. The serves to deny the interior of the chamber corrosive liquid. NEXT do not leave the pump inserted into the canister when not in use. The weekend is okay, long term is assured destruction of pump and the o rings. Lastly a fuel pump, a bicycle pump does not make. If you haul off and pump furiously on the little darling, it's going to break real fast. Lastly, coat the threads of the pump with a heavy coat of vaselline. Do not over tighten the threads. This will ensure a reliable and long term experience with the Ump. Let's examine if what I say is reality. I own a 25 year old MSR Firefly stove which is the fore runner of the current dragonfly. The pump still works fine and is reliable. I own an MSR Dragonfly, the pump is at least six years old and is reliable. In life, you reap what you sew. Regardless, even if the pump fails, simply get another. There isn't another stove system around that is as good as either the Dragonfly or the XGK EX. That's the bottom line. And what's so humorous about the complaints? All fail to recognize self failure and place the blame on the device and not the owner of the device. Who's running the Circus???

i own a dragonfly stove. i love my stove and have owned it for many many years. during this time i have had to replace my fuel pump three times. the entire fuel pump is made of plastic and prone to breaking. since there is nothing else on the market to replace it, i will be forced to buy these cheap plastic fuel pumps.

Can't 100% depend on anything

3 years ago

This came as the most highly recommended stove (pump) for winter. After years of ownership, but not that many uses, the pump started becoming unreliable. As far as I could feel, it wasn't passing on the pressure, just keeping the air in the hand mechanism and "bouncing back". Perhaps its a blockage, I don't know. With vigorous attempts, I often got it to work. But finally on a very cold winter, and the blockage cleared, it failed to build pressure in the bottle (even factoring in temperature). Because this is still the best solution I know, I'm going to buy two more of them (one backup), but I suggest people always have a full stove backup.

Great, but not for some older stoves.

6 years ago

The pump itself works great on newer stoves such as my XGK EX, however I purchased a replacement for my older WhisperLite and this is where I feel my observation should be noted. The original WhisperLite pump had a brass wheel for the control knob. The newer versions have a folding knob. Although easier to use in cases such as wearing gloves, the newer design comes into contact with the locking bail on the fuel line. Turning the fuel on is a counterclockwise motion and turning it off is, of course, clockwise. This has caused some concern since turning the fuel off comes into contact with the bail and hinders the operation should one need to cut the fuel supply in an emergency. Unlocking the fuel line from the pump would cause a pressurized fuel spray, thus causing a flare up. In conclusion, this is a great pump, but beware of its use on legacy designs.

Does not work with older Whisperlite-Dangerous

4 years ago

The locking bail on older whisperlites (miners from the 90's) interferes with the on-off valve of the pump. It has caused some very dangerous conditions on the trail. To fix this would require modification of the bail on the stove. Newer Whisperlites have a shorter bail. Does not simmer like the old one did. Sad, I loved how it would simmer with the right finess. No longer possible. Not the stove it used to be.

MSR needs to ship a new catch arm with their replacement pumps

4 years ago

I have a 90’s Dragonfly stove that I have had since new and the pump body cracked where the control valve assembly screws on. This is a common failure mode that many people report being a problem in that vintage stove. Can’t complain too much for near quarter century old plastic. I ordered a new replacement pump, which seems to function okay BUT the new design of control value interferes with the old design of control arm on the stove. You can easily turn the fuel flow on, but it is very hard to turn off-very dangerous! They should supply new catch arms with the pumps to avoid creating this hazard.

Very poor Warranty Service

4 years ago

I bought a new pump for my msr stove. I have accumulated 3 other pumps that had the same cracked lock on the plunger side. I sent the 3 in to warranty on 8/20/2020. They said 4 weeks. I called beginning October 2020 they said they hadn't gotten to it. Called mid November the warranty rep said they would issue 1 pump for the three. I said ok and the rep said it was shipping out that day. Called 1/10/2021 and the warranty rep said it hadn't shipped... I like MSR but this is my first time warranty and with this experience I will use other brands from now on. Pretty sad.

MSR pump

10 years ago

I have owned three of these to go with the Whisper Lite stove over the last 26 years of backpacking in the Eastern US and they have been very reliable during trips. The pump cup and o-ring seals tend to dry out in between trips, sometimes years, and do need oil and maintenance and parts replacement. The latest model, bought yesterday, has a cap on the fuel line that looks like it would block fuel uptake and I find no picture or mention of this in the instruction-maintenance sheet. So I will have to call for information that should have been included.

Great pump

12 years ago

I like that this can be left on the MSR fuel bottle when transporting. When releasing pressure after use it tends to "spit" fuel on your hands as it releases the pressure which is kind of a pain. I had trouble getting the pump to stay closed when using the stove but it did not seem to affect the performance of the stove.

The new pump does not control the intensity of flame well,

4 years ago

I bought this new fuel pump because I could not find my original pump. When the new pump arrived, I found the old fuel pump! I used the new pump and old stove on a recent camp trip in December when temperatures ranged from 33 to 40 F in the daytime. It was impossible to operate the burner on anything less than FULL STEAM AHEAD! The control valve would not throttle the fuel for a lower heat. It was impossible to simmer any water or food. Today, I operated the same stove with the original pump. It was easy to obtain a low, or simmering, flame. This is what I prefer, and I will use the old pump preferentially. On the other hand, the old pump would not yield a high flame, for a fast boil. I will be taking both pumps with me on camping trips. I will see how that works out.
