Haha, that guy sounds like me trying to explain to friends, family, neighbors how my 'roid powers everything, how my water system works with heat exchangers, etc.   Oh, the similarities!   (Except I'm not a hippie cohabitating in a collective like they are.... hahaha)

i don't exactly know why, but the dacha project puts a smile on my face, nice to see
the movement carrying on with yet another generation.

I need to research this water pumping system a little better. For watering my garden I use flood irrigation anyway. I have been thinking about using some sort of air starter motor for my AC when I get my SOM running. This should spin the compressor to take away the load of the start up. So I would need an air supply around for that reason. I guess if it pumped water also it would be a plus. DD

We would have never known especially looking at your photo.

DRDEATH, that Brumby Pump has definite possibilities, IF one has $500-$600 to "invest" in a 6 ft section of 4 inch PVC with 2 check valves and a float in it.
If a fellow could get a look at one, I feel that it could be replicated for under $50. Quite a markup, IMHO. I am seriously thinking about having a go at it.

Keep me posted. I can start a heart if it has stopped, I just have a little problem with other projects unless I see it done for the first time. DD

Not having a lot of luck getting a peep at the "innards". Hmmm, I wonder why .
Still digging..........

The water intake and discharge valves should be fairly simple but I have not conjured up how the air supply can be made intermittent. I think that is the key. I remember playing a bit with the innards of the old intake vacuum windshield wipers but that is a year or two ago

The Brumby pump approach really isn't anything new and airlift pumps have been around for a very long time:

http://en.wikipedia.org/wiki/Airlift_pump

I built an airlift water pump for a high school 4H project 35 years ago.  Here's a link to our US version Buffalo Pump:

http://www.groundwaterinnovations.com/how-buffalo-pumps-work.php

These sort of pumps work OK for pumping into an unpressurized system (i.e., an open tank for irrigation, etc).  Since these pumps introduce a significant amount air into the water, they don't work well for potable water applications unless you also take steps to treat the water and remove the air, and you still have to use a conventional pump and pressure tank to feed it to your house plumbing.  You also need a continuous duty type air pump...and you will ultimately expend more KWH to move the same amount of water than if you just used a conventional submersible well pump.  Primary advantage for using an airlift water pump is when you have sandy, abrasive water...in which case, using an alternative water source would be a better solution if possible.

I think you would want a diaphragm compressor so you don't get an oil accumulation. It makes for some ugly looking sludge. I haven't studied this design I linked too. but there should be a design that does not use the simple percolation effect to raise the water. I have placed positive displacement air sump pumps in explosion sensitive locations that would force up a long way (like 2 ft for every pound psi air supply pressure) No limit on water height either as long as pump intake was covered.. No idea of its innards; I was only one of the disposable monkeys installing it.

With that system you could pump into a pressurized tank with a float control to vent off the exhaust air but I think that would be a much more elaborate and maintenance heavy pump.
