Could the problem be the maintenance?

To address a few of the previous situations, 1) I also am pumping up my kites probably over 200 times a year. 2) 90% of those at near or below freezing temps. 3) Have NEVER maintained my pump. My pump, 4 years old, still works fine. My previous pump still works fine. Not sure what you guys are doing to wreck yours :roll: . I don't think it is the brand (mine happens to say Core, but guessing they are all the same). Now, Somewhat off topic, the issues I have had because of the cold - my pumps have gone to the wider and more 'beefy' plastic hoses. These get too brittle in the cold and break. Also, the 'kite end' of the hose inserts and hooks into the valve. I have had these 'hooks' break off over time. Assuming from cold weather, but maybe this happens to others?

But again, for those of you that are professing that you are religiously cleaning and lubing, and yet your pumps are wearing. Consider leaving your next pump alone - works for me :D

Nothing here. I'm just frustrated that the pumps we are all using are actually really crap, poorly designed to last only a season or so (depends on how often you kite). I clean and lube my pumps frequently too! But even with regular cleaning, I'm lucky to get through a season without going through at least 2 pumps.
How do you wear them out that quickly?
Mine is 10yrs old, never cleaned, regularly used on sandy beaches.
Same for my friends, they all have old pumps that are never cleaned and still work fine.
Very odd you and friends havent experienced pumps wearing out...
Maybe different conditions and sand than most others, or you dont ride when close to the freezing point?

I've had pumps from many brands, and all of them has worn out...

About one year, and they get "less perfect", and on the second year they start to get worse and worse.

EVEN when you take care of them - I always stove them away when out, so they are not in the sand blowing on the beach, and, based on experience if you dont, I lube them regularly which at least doubles their lifetime, also try not to pump too fast as this is no good for the pumps either, and sometimes I clean them too.
Other riders here have had pumps that lasts longer, but they dont ride very often...

I am out more than 260 session per year, approximately 300 kites are pumped each year, roughly.

And NO pump of the different ones will last, unfortunately, they get less perfect after a year or so, meaning typically the double pump action deteriorates at first, slowly.

They dont cost much so easy to buy a new one, but you are right, it would be nice to have some that lasts - I would gladly pay the double amount for one :thumb:

It is sand and other foreign material inside pumps that destroys them. Use a pump with a filter, and regularly clean and lubricate both the filter and the pump internals. Lubricating a pump without first cleaning it merely increases the grinding effect inside the pump.

You might be right John, I dont know, as most often not sand blowing where I rig, but even one time might be sufficient to destroy maybe :D

If so, which pumps has a filter and which dont?

We could make a list here.

Vintage, and subsequent quality control is the main issue that I have found with pumps. Given the exact same mold, some years lasted forever, some years blew out within the first few sessions.

Injection molding is a precision art. Yes, the parts produced are mass-produced, but everything must come together in a delicate ballet under the right conditions. Molds must be made correctly, plastic must be manufactured without impurities, plastic must be pre-heated to the right temperature, cooling times must be exact, injection molding machines must be maintained, and the final product must be handled properly until assembly.

All these things must come together. And the parts from one pump out of the exact same mold, may have tolerance issues due to all of the above factors, that create most of the issues that affect pump longevity and initial performance.

Matteo V....So it's a kite pump lottery..And I'm winning!

Matt, on a side note - check out the Walmart post. We won't even have to go to lake mac. Just drive 4 hours and STAY at walmart. :)

Hacksaw, skateboard, and trainer kite, and I should be good to clear all the light poles from the Walmart parking lot and go kite skating without ever having to get sand from the dead center of the US, all over my bedding in my van.

Long time lerker. First time poster. Friend and I have been looking into better solutions to extend pump life as well as create a new Kiteboarding pump with riders in mind. I'm excited to receive some feedback from y'all on the kiteforum about this pump. Something I've been working on for six years.

The pump has a chamber built within another chamber. For a higher pressure mode that will reduce the stress on the pump as it no longer has to work as hard to inflate with.

Is the 1.7l mode enough to pump up a SUP?

Yes, it is. Will pump up a SUP much faster than traditional SUP pumps. I have a video on FB don't know if the URL will share but will try.

I look after my pumps and never had an issue. Started with the small backbreaker and now use the tall pump (WFMG). I give it a clean every now and then and add more vaseline. I keep mine in a bag and never leave it lying around to get sand in. I have also added a plug to block the intake point so when not in use no sand can also get in. My hose is the more robust rubberized one with screw thread to the pump as I have had two plastic hoses break over 12 years. I also had the base crack on one. In saying this perhaps there is a market for a more premium pump with better quality materials that may last even longer but the way I see some pumps treated they are very disposable to some kiters.
