![Testing Different Water Pump IMPELLERS - Which One PERFORMS THE BEST? [REMAKE]](/img/n.gif)
If u are going to comment that I should use more powerful motors, well... already done this: czcams.com/video/57A_l9_b610/video.html
I have a great idea for gears and electronic motors I would really appreciate it if you would meet with me and have a conversation about it
I actually want to propose you adding some PWM
you can save water by putting exit hose into the bucket
Can you measure the water head and how well it compares with equivalent commercial pumps?
Hey do you think that you can make a mini version
I work as a mechanical engineer making screw pumps. We make everything from pumps the size you see here, to pumps that have 50" diameter collums. I have to say, this is seripusly impressive!! To get that amount of flow with such small electric motors and 3d printed parts is awesome, love the video 😊
But it's loud as fuck only ok for basically nobody
@@royaldecreeforthechurchofm8409 I could easily use this for drip line irrigation, no one is going to care ... maybe the chickens.
@@royaldecreeforthechurchofm8409 It will actually get quieter as the gears "run in", and, in many applications, no one cares, for example, in the middle of a corn field, and, in many cases, it only needs to run intermittently.
I like that it has some system redundancy, great for remote operation, and uses cheap motors, coupled together to get reasonable, and scalable, Power... I suggested one-way drive mechanisms on the motor, to prevent a motor failure from stopping, or slowing, the pump... I wonder if the gears could be printed in pom/delrin? Knowing zero about filament availability ;-). Also, maybe the gears could be run-in before final assembly, and run in a sealed enclosure with a light lubricant bath?
Will The plastic need lubricant?
The water is not leaking into the gearbox, it's just coolant for the gears 🙄😅
Genius, multiple problems solved.
The same way PC watercooling float bearing pumps are cooled and lubricated in water.
@@Thetreetroll Easy there, Todd.
@@Thetreetroll Except for the rust...
If you have a problem, call it a feature.
You should test to see how high the water will reach vertically in a clear tall plastic tube to find out the pump's head pressure.
"This is really boring part, nothing to speak about this, fast timelapse"
Love it... more youtubers need to adopt this kind of attitude hahaha
Thats when I hit subscribe. lol
but then, how will they add 700 midroll ad??!?!??
I love his very literal English.
lol, yeah. there are videos out there where they don't even bother removing the loading screen that last quite a while, only commenting that their internet is slow...
7:12 maybe build a second pump which pumps the gearbox dry xD
then one to pump that one dry xd then another lol
@@Capricorn_media_group no i wrote the gearbox, if the second pump gets wet its not problem. You could use a cheap aquarium pump for underwater use.
Longer shaft between the gearbox and the pump, along with some drainage holes, could make the trick
🤣
Nah you're looking at this the wrong way, bruh. It's not a leak, it's a total loss cooling system 👍
Cool PoC but the water spraying over the contacts gives me anxiety attacks.
That won't do much because of the low voltage but the water will certainly kill the motors due to corrosion.
it would be bad if it were saltwater, still nothing too major.
It’s fine as long as you blow them out with an air compressor when you’re done.
You can actually break in a brushed motor completely under water. RC car racers do it.
@@mjodr Wrong. You can take a BLDC motor in water, not a brushed.
Love the content but watching you use the needle nose to tighten that bolt bothered me in ways I’ve never been bothered before 😂
Yeah I hear you there lmao
Ha ha ha I was thinking the same thing, there are so many other tools you can use. Even a pipe wrench or vise grip, anything else. Don't know why that bugs me so much
You could make another 9 minute video explaining all the engineering, fabrication, design, and assembly errors in this little project 😂
Also he way over tensioned. That's what really bothered me
@@224rebels what were the torque specs?!
Gonna need that for my next watercooling loop for my PC...
Dude are you building a personal reactor?
@@nopparuj Will probably need a pump like that if you plan on using 4 3090s
I hope you have noise canceling headphones
@@JohnDavidDunlap Don't worry the PC will be in an anechoic chamber. I'll be in another room curing cancer with that much graphical power.
@@nukem1839 Do you have a truck for a pc case? Most can't even fit 1 3090
For the water getting into the gearbox: add a O ring slot into the body where the rod goes to the impeller and add a O ring. Sealed the impeller from water going through bearings. Now print a cover for motors and gearbox.
I agree with this guy
I wouldn't use an o-ring but rather a oil seal in either nbr or fkm
Correct term would be axial seal, o-rings are for static environments
@@teemuuusitalo7987 this is something that won't be used for prolonged time but I agree, it is a bit inadequate. Self filling shaft lip seal would be the best since it works on boats, it would serve here also.
Try making a packing stuffing box, can use a rag or something for the packing. The packing is water cooled any way drill a hole in the bottom for a drain

Я с трудом терплю индусский акцент, это такая жесть )))))))
Хорошо? Зверни увагу як протікає помпа з усіх боків
Достаточно было пройти в описание канала.
For water-tight shaft housing, check out a "stuffing box". Basically, you make a cavity for the rod to pass through, and you stuff the area around the shaft with valve stem packing material that's a cord with graphite lubrication on it. The packing allows the shaft to turn but creates a water tight seal around it. This is how some faucets and ships have a rotating shaft that prevents water from seeping in.
hehehe cavity rods
Learning another language is so under appreciated great job man keep it up
Your spacer's shoudn't cover the 90% of engines cooling holes.
its water cooled
@@badwolf5245 xD
Motor*
nobody cares as the pump leaks anyways, and is not designed for long term use.
I think those are not ventilation, but rather are simply for holding the motor together.
I might be tempted to make a "hot rod" motor for a powerwheel out of that design. Neat way to make an super compact and portable high output water pump. LOTS of potential uses. Thanks for the video
That man is fearless, spraying water all over the electronics 😅 Nice project man!!!
I mean they're low voltage high current electronics, they won't get bothered by water
Pretty amazing flow for a centrifugal pump without involute shaped housing. Awesome work all around. Straight forward, excellent communication skills etc. Enjoyable experience.
with metal gears and more powerful motors, this could perhaps move a car because of the torque
Not engine its called motor
With more power can make bigger thing move. Very smart statement.
@@collinblatchford yes, mainly coming from a drill motor
I came to comment section to confirm what my ear is picking up. Glad to see fellow Estonian bringing something nice to the eyes of youtube, keep up the good work!
This is so cool
I am glad we have smart people in this world

ESTONIA!!!!!!!!!!!!
You, and this video, were the reason I'm into engines, electricity, and gears, Thank you.
Edit: The water spraying EVERYWHERE is probably going to cause a short, that is if the water some how lands in a way that connects the positive and negative of one motor.
why not attach the motors radially around the gears so you could use less of them and it be smaller
Installing the motors with the drive gears coaxially to the main shaft would also decrease the friction and the noise pollution
Thinking about it some more, the motors should be connected via a differential I think.
@@mafiosomax7423 If you care about efficiency I agree, as those motors are likely not running at exactly the same speeds. But it would increase complexity and part-count significantly which would probably require more maintenance
Assembly would be complicated as the main shaft would not have clearance to be placed in from the top.
@@mrbearman_7735 if you cared about efficiency you would waste your time and just get a larger 12v motor instead of 8 and a gearbox
Great job! Nice project. Keep up the good work!
Thanks, I will for sure! :)
Oh hey it’s the guy with the really cool hand
I recognise that hand!
@Uncle Eidolf Yeah, this is a 2008 Honda Civic. No, I don't have videos about it.
🤔😎😎😎🤔🤔😎😎😎
thanks for making the files free
good project, a float switch on the bucket would be good - when the water is low it switches off the pump
This was really cool. I seriously did not expect so much power from those tiny motors. I look forward to seeing the further iterations
Please make mechanical seal and put some grease onto gear box

He also didn't polish the tip of screw pushing the rod , that annoyed me the most for some reason even though there are bigger flaws.
I used to be a travelling spa and jacuzzi repairman. This pump design looks grat for such a small power supply.
Fun build!
Damn imagine this with a rc car brushless motor
I was wanting to something similar. I believe you would need a special ESC to monitor the speed of all the Motors.
@@ryanrinn4041 Depending on how you wire them the same ESC could control all 8 of them. It might actually be preferable as you wouldn't want any one motor to be out of sync with another. Just make sure to calculate the voltage so the ESC can handle what you attach, and scale the motors down so they don't overwork it.
@@Scott_C I wouldn't put more than 1 brushless on an ESC, it might work on the bench top but under load the ESC will freak out.
I'd use a single bigger motor or maybe a couple slightly bigger motors and give them an ESC each, they're cheap and literally plug and play, easy
Excellent concept! Now try reversing the design and have a propeller turn the motors into generators.
Scott C ineficent
It's not that simple as those can not match the efficiency of turbine blades.
Put an elbow on the pump so the gearbox can be vertical. No more water leaking through the bearing. Very impressive.
I love the idea of you using this in a boat :) for power, that would be sweet.
ABS on väga tänuväärt tooraine printimiseks. Eeldusel et ei pea printeriga tuba jagama.
But food for thought for ver 2.0 - maybe the motors could be rearranged to all hook up to the same big planetary gear. So the gearbox would not be so long and bulky but more like the star configuration of an airplane engine.
I guess water is the perfect thing to cool those electric motors!
And the bearing
linus approved
Brushless and brushed motors actually don't care about water, you can run them under water without issues, so the spray won't hurt the motors. It is the electronics that have issues with water.
Designed correctly it is surprisingly effective.
@@garethbaus5471 I'm not questioning how effective water pumps arr
Beautiful work! I would be interested to see This used a platform to compare different impeller geometries
Thanks, looks fun to build.
I'm Korean, and this suddenly appear on my recommend list.
I love this project!
Thanks for amazing video.
Thanks! I have been in Seoul, love this place! Also a fan of Blackpink! ;) 😎

That ia actually amazing! The principal is fine, just some work to prefect it.. for example full cover, power switch etc.. overall, I'm impressed.. Good work and keep improving!
Powerful moter is working well with the gearbox 👍👍👍
this deserves a SUB
To prevent water from entering the gearbox, you could use a magnetic coupling and seal the pump and the gearbox. A lot of aquarium and fountain pumps are made like that.
Wow I never knew that thank you so much for this comment
Wouldn't you lose a lot of torque with that?
According to the motto: "Why simple, if it could be made very complicated?"
because very complicated redundancies make it more safe as if one motor fails you got 8 more before it stops working although you loose a fraction of torque and speed
Half the videos on youtube would be gone if that were the motto, this is great entertainment.
works better than my brass one!
You really need to put a seal in front of that forward bearing.
Well done Rafael Nadal 👏 👏 👏 👏
You saying "wudderbump" makes it very entertaining.
Ahh, philips head screws, I am dying inside! I had to use some today on a small project because it was all my hardware stores had and it really made me appreciate my hex socket set (wish it came with some tapered). Great videos, keep it up! I love seeing 3D printing being used to make more than just simple tools and vases.
hex? i'm dying inside. square drive
@@artfulgamers4665 really? for machine screws? at least hex is super common and does not strip as easily like philips.
Nice job and thank you!
You could say...
I was quite pumped for this video...
Кого он обманывает?! У него клей "момент"))
For durability upgrade on metal contact in end of the rod. Make sure both surfaces are cut straight, center punch mark on the both and drill very shallow hole using say 10mm drill bit. Get one ball bearing ball, apply little bit grease, hold it on place and tighten the bolt. This way you have smaller contact surface creating less friction and hardened ball bearing ball wont wear out that fast. If you are worried bearing falling out, there are those long nuts that you can tread over the bolt that prevent bearing ball from falling out.
Of course this is based on what ever those gears can last more than day continuous use, but mentioned friction could start melting plastic, so its worth to do such minor modification.
For water leaking, you can use silicone on axle and bearing inner race and make flexible disk that connects to shaft, put generous amount of grease between the disk and frame, this way if pumps pressure increases it will push disk against frame and works sort of one way valve. If pressure wont increase disk will just cause small amount of drag moving the grease around keeping healthy amount near the axle and bearing preventing water getting to bearing. Optimally you want to get water sealed bearing for that combined with silicone on both inner and outer bearing races, but that DIY sealing should work ok and for those who have difficulties to find sealed version of said bearing.
that's powerful 😳
This is dope
Pretty cool, I think you could have put a restrictor or a variable speed switch to control the flow and keeping the reservoir at a constant level after watching for how much drawdown you can manipulate.
Or just pipe it back into the bucket.
7:12 if you ran your output (of water) back into bucket, you could reserve water and not spill as much on the ground. Make less mess.
Wow impressed by the flow rate
This was awesome!!!
Looks great. Have you tried experimenting with different shaped blades in the actual pump housing? I would be interested in what blade shape (straight vs curved, and how curved) would work the best.
And you've got a sub. This is awesome.
Really cool design. Would love to see its limitations on how it can pump a column of water
Good little D.I.Y project for off the grid applications.

EST
probably the most useful concept I have seen
Leak proof is the hardest part, I designed mine before 3d printing but used a long shaft supported by bearings with disc walls and o-rings to "minimize" the amount of water before the gear box, you could also put a gear on the horizontal shaft and have your gearbox angle down into that before the shaft enters the propellers work area.
Was a bit surprised when I saw the channel in estonian (:
Keep it up!
Would be interesting to see when you attach an pressure gauge to it an see how much it produces
Also nice build 👍
czcams.com/video/3LHZXBUxGS4/video.html
amazing!!
Thats pretty awesome
opposing pinion gears would take care of the "thrust bearing" issue
Keep doing you dude! I love these types of videos on these topics, there really interesting! I hope your channel grows fast!
Thank u mate.
@@LetsPrintYT Total Power Consumption and How much was the approximate Discharge per minute?
EXCELLENT,^^
Wow that’s awesome
So putting 8 motors in parallel gives you a lot of power which is great if you have a huge mass of water to displace, but it does not increase the pump speed. Perhaps though you could find a configuration to increase the speed of the motors dependent on the load exerted?
well, it slows down while pumping which means it would need even more torque to reach higher speeds
That is amazing and powerful i realay like it
Keep going ❤😊
And i really like ur accent ❤😊
Fascinating
Cool project!
Tere tere!
Good content here, northern neighbour!
Woah, a wild Estonian. I happen to know a guy who lives in Estonia. Beautiful country my man, hope to see it sometime in the future.
Thanks bro, my water fights are going to be world class now!
This will be sick to use on a soft wash system. It will be much cheaper than buying a 8gpm pump. My college has a 3D printer. I’m considering downloading software and uploading the CAD into the software to print the part. Freaking 30 bucks for a ridiculous pump, this thing would be great yo sell on forums for contractors looking to buy affordable pumps.
Suggestions, first, look into sealed thrust bearings, they would work really well in this situation. Second, leave a gap between the impeller section and the gearbox to give leaking water a place to go other than the gearbox. Third, more thoroughly seal the impeller housing and seal the gearbox, with covers for the motors. Fourth, use grease(preferably marine grease to reduce pollution issues). It should reduce noise, protect the surfaces from friction damage and help waterproof the system. Fifth, grind flats on the shaft where the set screws on the large gears will be. Set screws do better at grabbing a flat surface than a curved one. And last, look up a better impeller geometry. You can make any shape you want with a 3D printer, you might as well make an effective one
I was thinking a print in place labyrinth seal and then grease.
Can you do a power drain to see how much power it takes to run it and for how long
@satisfied man i ment his set up
i love your gear boxes!
Great job!

I have been looking forward to this kind of build for ages. I'd love to use screw pumps for diy stuff but you can't exactly buy one at the hardware store.
Cool, i used to make water pumps all the time out of legos when i was young. Tried it again a year ago using a turbine from an old water powered toy and a case from an old electric motor, I just made a hole in the side, used a motor shaft then made an intake, best water pump i ever made. This video gives me some cool ideas.
