Pulserpump Nano World's simplest pump without the digging!

The pulser pump nano allows you to make a pulser pump without digging a deep hole in the ground.
I made my pulser pumps 20 years ago based on the materials available at the time and what I could do. Other people are reluctant to dig deep holes for pulser pumps. The pulser pump nano uses a smaller tromp section so you do not have to dig so deep. To compensate for the lower pressure, instead of one wider airlift pipe people will use a bundle of 1/4 inch 6mm or smaller tubes for the airlift section. Please check it out and if you have a suitable site, please make and test this. I cannot currently try this because I do not have an available stream or river.

Sorry, I need to ask. Does it have the same principle as a normal Ram pump? In that case, by "without the digging", do you intend that this pump could extract water from a pool/lake just like a normal electricity pump, without the need for a "fall" of the water?

@0rioni Hi, it still needs a fall to work. So you still need a dam at least a ft high. 1.5 ft is better of course. but what you don't need is to dig a hole 10 or 15 ft deep beside your river or stream. If you can get something like one of those big 40 gallon rain barrels into the bed of the stream at the exit side of the dam, that should be deep enough. You have a pipe over the dam and into the barrel, collect the air bubbles at the bottom and pipe them to your nano airlift pump.

@gaiatechnician - you said "collect the air bubbles at the bottom and pipe them to your nano airlift pump."

I am not able to understand the principle of that. Can you be a little more specific and broad in your explanation. What I am trying to find out is: I know that with a normal Ram pump, it needs to be placed 2-3 feet below the water level, and you can solve this by digging a hole. But the water that comes out of the waste valve will soon fill that hole with water, and the pump won't work.

@0rioni This isn't a ram pump. It is an airlift pump powered by a tromp.  You can find more info on appropedia, wikipedia or internet glossary of pumps. (or my pulser pump videos). Thanks Brian

@0rioni As soon as I get time, I will try to put a clarifying video on.

Thanks Brian

Thanks for drawing the picture! Now I can continue with this Nano Pulser pump project.

@gaiatechnician I erred on the air volume measurement. I rechecked and found a pipe kinked. Real value is 1.4 liters per minute of air produced. ( I don't remember if I used "full air power" on the test that brought water to 13 ft high but anyway that is the figure today). Note that my aquarium pump is a found item. Someone dumped it on a country road and I found it coming home from work. So it is suspect quality.

@Cyber000000 The windowfarms people just use their electric powered bubble pumps to circulate water round their hydroponic plants. but this might be 10 or 20 times more powerful.

So this could pump water from wells, it could circulate water round hydroponic greenhouses or in water features. Basically the same applications as the big pulser pump except for the aeration of animal slurry and stuff like that. I think it needs more pressure to do that.

[Cyber000000]

@gaiatechnician Thanks for the measurement. What kind of applications do you have in mind?

[gaiatechnician]

@Cyber000000 I have no site to test it out. But if anyone has a site, a student, or retired engineer or a teenage kid on a farm could do this. And harvest some numbers!

This has serious potential. My other videos show pumping to 13 feet high from an aquarium air pump that delivers just over 1 liter per minute of air at atmospheric pressure! (I measured a minute ago). My old pulser pump pumped 3.5 to 4 liters per minute of water to 10 ft high. In a day, that is a lot of water.
