Thanks for sharing that. I have seen a lot of Glen's videos with water flying everywhere but this video, without any water, actually has some hard fact that someone can use to actually build one.
Frederick Henderson Thanks, I have great respect for Glenn Martinez he is an aquaponics genius. He does sell a book that probably enters in detail on how to build most of his devices and systems. Still I do believe this pump can be tweeked for more water volume with a few modifications. As soon as I get a chance I'll post a video about the mods. Thanks again for positive comment.
Charles Kiplinger I got aprox. 90-100 gph on a 32 litter per minute air pump (25 watts). A collector enhances the performance of this design. I have increased the volume of air and the pump increases it's output; although I've haven't done a measured comparison. I'll make a note of this and do a measured comparison and do a corresponding video. A tip for anyone trying this design: Their should be no bottle-necks. For example: if you have a 2 inch pipe than the check valve should be 2 inches as well. The pipe going up would be 1 inch and so the ratio is 2:1. I hope this information helps people. Maybe I should upload a video on how I built it and show it in operation. Let me know what you think. Thank you for your comment Charles.
Irvin Carrero and Charles Kiplinger 2 comments the pipe carrying water should be 1" or 3/4" or smaller. Bigger than this it he geyster effect (one big bubble pushing the water) no longer works. Not my research from the book "Recirculating Aquaculture". 2nd thing, Irvin you are at or close to sea level correct? At what altitude are you Charles? I am at 702m(2,303 feet) When I convert that altitude into meters of head (or feet of head) on onlineconversions.com I get 0.86m(2.82 feet) of head. If I am understanding this correctly I will need to go down that distance just to equal sea level. My guess is that without that added depth to compensate for the altitude I will see reduced pumping rates. Anyone have any hard data to back this theory up? +Glenn Martinez +Natalie Cash +Bob Campbell +Aquatechnobel
Irvin Carrero Charles Kiplinger Glenn Martinez Natalie Cash Bob Campbell Aquatechnobel OK, I calculated the effects of altitude on airlifts / geyser pumps another way. Using onlineconversions.com I first converted 1 atmosphere to meters of head, 10.335m (33.899 feet). I then took my current barometric pressure of 963 hPa and converted it to meters of head, 9.557m I then subtracted the two and got 0.778m (2.552 feet). This is very close to the calculation in my last post of 0.86m (2.82 feet), where I used my altitude to calculate head. My theory on the effects altitude has on airlifts and geyser pumps is the higher the altitude the lower the pumping rate. Why? Because we are not releasing the air under the same pressure as at sea level when we are at the same depth below the water surface. This means that the release point needs to be lower just to equal pumping rates at sea level. It my case almost 3 feet lower. Does anyone have data or experience to back this theory up? I would be happy for input proving or disproving or correcting my calculations. Thanks for your valued input!
Frederick Henderson Irvin Carrero I went to one of Glen's other pumps he demo'd, a buried sump system, and am getting over 100 gallons an hour now. Thanks
Charles Kiplinger Hi Charles! Would you mind providing a few more details? What is your altitude above sea level? How far down in the water are you releasing the air? How far are you lifting the water above the tank you are pumping it from? What size pipe are you using for the lift pipe? What size pipe are you using for the air chamber? and how long is it? Thanks for any concrete details.

Frederick Henderson I agree this video is useful for me too, with the eplanations that are nice. thanks.
thanks for taking the time to explain your tech
Hi Irvin, thanks for your video. Where did you get your check valve and How was the performance of your pump? Thanks!
I love airlift its cheap and safe to use
does this actually work.
what height can u get?
post a vid of it in action.
Irvin, How did it operate? I've tried one exactly like it, using the 70 lpm pump, and have gotten minimal results.

HOW TO MAKE?
isnt it more expensive when your getting 100gph from 25 watts? from water pump you can get 530gph from 25watts
tell me, what 25 watt water pump can get 530gph? from 12-14V without 12V in 220V converting. Deep 6 meers. Say model? ))) Workin on 1 solar battery
