How To Build A Pneumatic Ejector (Air Lift) Pump Using a 3 Gallon Bucket
Вставка

- This is a instructional video how to build an external (non-submersible type) pneumatic ejector pump using a 3 gallon bucket as the chamber.
I re-invented this pump as I began tinkering with air lift pumps and aquaponics. Sadly, I wasn't first to invent and it had been patented in the 1970's. I believe this pump is best for the aquaponics application as it will not clog and there is relatively low maintenance. In my previous builds, the chamber was 1-2 liters and submerged inside the fish tank. This version is 3 gallons so there is slightly less time wasted during the refill and purge stages when compared to the smaller chambers.
This external pneumatic ejector pump would be best suited for the outdoor grow operations as the "sneezing" noise from the sudden rush of air and water as the pump goes from purge to refill mode may be beneficial in scaring away wild life. If this pump is used in an indoor application, I would advice building a muffler device for it to dampen the gurgling noise it makes.
The smaller air pump I used in the video is a 6 watt Active Aqua aquarium air pump.

WARNING! DO NOT PUMP HIGHER THAN A COUPLE FEET (4ft MAX). A BUCKET IS NOT RATED FOR MUCH PRESSURE! DO NOT PRESSURIZE THE BUCKET BEYOND 2PSI! IE DO NOT USE AN AIR COMPRESSOR FOR THIS! Keep this in mind when selecting an air pump. If you need to pump higher than a couple feet, select a chamber ("the bucket") and piping that can withstand the pressure.
The parts list include:
1x 3 gallon bucket
1x air tight bucket lid
4x 3/4" pvc 90 degree elbows
1x 3/4" pvc "T" fitting
1x 3/4" pvc union
1x 1" pvc union
2x 1" rubber grommets
a couple feet of 3/4" pvc pipe
1x plastic water bottle
1x tall plastic sports water bottle
1x air fitting of choice
1x rubber bouncy ball
1x bbq skewer - Наука та технологія
Finally! A concise, intelligible, practical solution. Thank you! Love the quacky duckspeak on the sped up segments 😀❤️
Brilliant! Thanks for posting. Nice work.
great video, thanks for sharing
Very interesting design!
Great system!
Nice, I will try your amazing bucket pump for my aquaponics installation. Hopefully, it works
Very nicely done, you are quite the videographer ! It seems that many of us are scoping around for a more effective setup to lift simply out of a deeper water as in a well with low pressure air. So far the simple air bubble lift, gun by gulp, is the best, or most economical anyway that I've come across yet for less pressure needed but I'm supposing your system is more effective and efficient for less lift height. I'm particularly interested in an emergency well pump that uses a low cost air pump such as a foot/treadle style. Thanks for your hard work!
Thank you for such a simple, straight-forward and clear demo. Watching the video brought to mind something my father, a carpenter by trade, would often say, "Having the right tool completes 50% of the work." I think the ease with which you present the demo has much to do with having the right tools on hand. Kudos!
you prolly dont care at all but does anyone know of a method to get back into an instagram account..?
I was stupid lost my login password. I appreciate any tricks you can offer me.
@Larry Colin instablaster :)
@Idris Devon thanks so much for your reply. I found the site through google and Im waiting for the hacking stuff now.
Takes a while so I will get back to you later with my results.
@Idris Devon it worked and I actually got access to my account again. I'm so happy:D
Thanks so much you really help me out :D
@Larry Colin No problem xD
Interesting video overall. Thanks for the build. I hadn't heard of these till 2 videos prior and was looking to see what they were and how they were used.
Those aren't unions, they are couplings. A union has 2 sleeves and two caps. The caps are screwed onto a center piece that "unions" to the two pipes together. This is a joint that can be taken apart. A coupling is not designed for disassembly, it is glued in place.
Ah Thanks for the correction. Sometimes I call things the wrong name and not even know it.
Would this work for my aquaponic system? I have my sump tank ~4 feet below my ground level, and i need to pump the water vertically up the 4 ft, and up a small grade (about 2 inch) over 30 feet.
Cool design!
Have you tried a percolator design? Basically a aut-stone in the bottom of a lift pipe that when the air is pumbed in will lift some of the water up with it.
I'm just wondering is that would not be easier to make and use less air as you don't need to lift as much water as you're not relying on the water displacement of the whole stack of water in the bucket / lift pipe but only need to generate enough pressure to displace the water column in the water reservoir up to the level inside the lift pipe and then from above that level you are using air-flow to lift the water further up.
If that made sense to you that is! ;-)
Hello, I need to know if you have a video or if you know how to extract water from 30 mts of depth with a air lift pump.
Hi, nice share can I make it for my 1000 ltr water tank for in small size with one inch out pipe 5 feet high in other tank with continuous flow like your.
Will it continuously flow without jerk?
Hi I made the neumatic pump like in your video , it pumps the water ok but does not fill the bucket, can you give me some digestion on the problem ..... Gracias
Hi sorry for the late reply. Does your pump simply blow air and gurgle after it pumps the water out? The problem with refilling your bucket will depend on how you have it connected to your bucket. The refill rate needs to be at a certain rate, if it is too slow, the internal air siphon of the chamber may not close. Do you have a water reservoir connected via a "u" siphon or is the reservoir have a pipe at the bottom of it connected directly to the bucket? If the former, the problem could be in the "u" siphon. Otherwise, you may also want to check if the reservoir's water level is high enough to give adequate pressure during the refill stage.
our grp need to one model of pneumatic or hydraulic pump can u give an idea
Thank you so much for making this video. I'm a beekeeper who's intrigued by aquaponics. This got me thinking, pumps for honey are expensive, like $1k. Also, honey must be heated to lower the viscosity. I'm curious if a pump like this might be a fraction of the price and work better.
I may be doing some experimenting in the next month. Water is about 8 lbs a gal, where honey is 12 lbs per gal. So higher pressures would likely be required and a typical pail won't cut it. I'd be curious to hear your thoughts, @jlock8! Great job.
maybe a bucket reinforced like this might allow higher pressures whether you're pumping water faster or honey.

Hi Jimmy, is
the overflow on the inflow from tank needed? Any reason why a straight inlet pipe couldnt be used?
Hi There! A straight inlet pipe going to the pump would work just fine, the reason why I have a weird set of plumbing on the inlet is because I didn't want to drill a hole in my aquarium tanks. Is that what you were referring to? I hope I am answering the right question.
Hello greetings, I would like to help me with a project. I would like to draw water from a well of 100mtr to deepen I would like to know you could you give me some option of pneumatic extraction .. thanks
I'm trying to build a similar pump to the one in your video. When I initially fill the bucket with water and turn on the air, the water ejects just fine but never refills. I can feel the air flow from the outlet pipe after that. Any ideas?
thanks for the suggestions, i will give it a try. Thanks for posting the video. Very cool concept. I'm trying to add a little more flow to my aquaponic system to expand and this seems like a good love energy consuming option
As I see it, the stand pipe in the final scene connected to the tee-fitting would break any siphon.
Since the bucket is not transparent, and the video is so short, why should we assume the water coming out of the bucket isn't simply replaced with air?
Too many questionable items in this build.
What is the total height that the water is lifted? I need to lift water about 180 cm (70 inches) - from the bottom of one blue 55 gallon barrel into the top of another stacked on top... do you think this would work?
Hi Mike D, this particular design only lifts about 3-4ft. I haven't tried going any higher as the bucket may not be able to withstand much pressure. However if you use pressure rated PVC pipe, it certainly can work and you are only limited by the air pressure supplied, and the pressure ratings of the pipe fittings. Also you'd have to be more careful of the one way valve design (needs to ensure it wont jam under pressure, so a rubber ball may not work. Perhaps use a marble or an off the shelf flapper valve instead?).
@@LockeLaboratory this is awesome, need this to lift water into filtration system for my pool to pond conversion......ould be awesoe if you could MacGyver a 40 to 55 gal container lift system...I'm not that talented, the use of the bottles would be too small or flimsy?
@@Mrsboncouer do you mean to make a pump out of a 55 gallon drum? Never tried but it should be possible. Not sure the pressure specs of a rain barrel but since it is so tall it may have to be buried. How tall are you thinking to loft the water?
@@LockeLaboratory didn't mean using 55g drum...but maybe 10 or 15 gallon, more solid barrel could handle the pressure better...i need to pump from the pool up to a 3 barrel filtration system....about 9-10 ft high from pool bottom to top of filter.
What happened when you speed up pump? It looks like something wrong
Monkey Host hi, it was working normally. what happen is it purged all the water out of bucket so then air siphon activaxed and started a refill cycle. when pump refill with water, air pump will purge out water again.
Where could I buy black rubber?
I need to make a similar tank
Hi, I got my black grommet off of McMasterCarr. There are other hydroponic suppliers that may have food safe versions however.
@@LockeLaboratory Thanks for answer.
I want to make submersible

will one way valve works? use one way valve instead of rubber bouncy ball
Yes, it depends on the spring force of the one way valve you purchase. If it is too strong, the water will not fill back up. I'm sure off the shelf valves spring tension can be modified or if you use a flapper valve in say a toilet which has no spring it would work as well.
It is why I made my own with a rubber ball since there is very little force to open the one way valve.
@@LockeLaboratory i have two tank (one at top and the other at bottom), currently i am using 200w water pump transfer water from bottom to top. if extend the drainage pipe to reach the top tank, will it works?
i recognize that bucket its for a bakery lol
My dad asked the bakery for free buckets :)
But a submersible water pump is like 10 bucks

air pump tooo noisy my fd
