Extremely Powerful 3D Printed Gearbox & Water Pump - Eight Electric Motors 

If u are going to comment that I should use more powerful motors, well... already done this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-57A_l9_b610.html

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 😊

The water is not leaking into the gearbox, it's just coolant for the gears 🙄😅

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

7:12 maybe build a second pump which pumps the gearbox dry xD

Cool PoC but the water spraying over the contacts gives me anxiety attacks.

Love the content but watching you use the needle nose to tighten that bolt bothered me in ways I’ve never been bothered before 😂

Gonna need that for my next watercooling loop for my PC...

Learning another language is so under appreciated great job man keep it up

That man is fearless, spraying water all over the electronics 😅 Nice project man!!!

with metal gears and more powerful motors, this could perhaps move a car because of the torque

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!

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.

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.

This is so cool I am glad we have smart people in this world

Я сначала подумал "какой у чувака сильный индусский акцент! но потом уидел клей "Момент"!))) Молодчина, у тебя очень хорошо получается.

ESTONIA!!!!!!!!!!!!

I love the idea of you using this in a boat :) for power, that would be sweet.

Your spacer's shoudn't cover the 90% of engines cooling holes.

Great job! Nice project. Keep up the good work!

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.

Кого он обманывает?! У него клей "момент"))

why not attach the motors radially around the gears so you could use less of them and it be smaller

Damn imagine this with a rc car brushless motor

You saying "wudderbump" makes it very entertaining.

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

Please make mechanical seal and put some grease onto gear box

Готов был поклясться, что автор - индус, пока не увидел "Момент" :-)

Pretty amazing flow for a centrifugal pump without involute shaped housing. Awesome work all around. Straight forward, excellent communication skills etc. Enjoyable experience.

good project, a float switch on the bucket would be good - when the water is low it switches off the pump

I'm Korean, and this suddenly appear on my recommend list. I love this project! Thanks for amazing video.

I guess water is the perfect thing to cool those electric motors!

works better than my brass one! You really need to put a seal in front of that forward bearing.

probably the most useful concept I have seen

According to the motto: "Why simple, if it could be made very complicated?"

Excellent concept! Now try reversing the design and have a propeller turn the motors into generators.

Powerful moter is working well with the gearbox 👍👍👍

I used to be a travelling spa and jacuzzi repairman. This pump design looks grat for such a small power supply.

В чем смысл? Нельзя просто помощнее двигатель взять? Зачем усложнять конструкцию?

This was really cool. I seriously did not expect so much power from those tiny motors. I look forward to seeing the further iterations

Put an elbow on the pump so the gearbox can be vertical. No more water leaking through the bearing. Very impressive.

You could say... I was quite pumped for this video...

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.

Я думал ты из индии пока клей не увидел :)

Thanks bro, my water fights are going to be world class now!

Well done Rafael Nadal 👏 👏 👏 👏

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.

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.

Damn you could get hundreds of water feet uphill with that little plastic pump.

thanks for making the files free

Was a bit surprised when I saw the channel in estonian (: Keep it up!

Do not question the accent, he knows what he's doing

Good video. Reasonably good English with very little accent, clear and easy to understand.

you are so underated, you should’ve been at 1M subscribers right now

Your channel is growing rapidly. Brace yourself! The YT algorithm likes you right now.

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.

its amazing that he didnt get shock when that much water spread

That’s a great design, the motors are water cooled.

Can you do a power drain to see how much power it takes to run it and for how long

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?

his english is honestly the best

Wow impressed by the flow rate

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!

Tere tere! Good content here, northern neighbour!

The water in the gear box is acting like a coolant and is helping to keep the gears from getting hot

water + electrical power != friends

opposing pinion gears would take care of the "thrust bearing" issue

Beautiful work! I would be interested to see This used a platform to compare different impeller geometries

Printing the gears and impeller out of HIPS would make it much more long lasting. Great project

Твой английский прям вери бьютифул мля

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.

That's more powerful than anything I've used from the hardware store.

The best home Generator project, thanks

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.

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.

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.

A little water proofing, and this is an actual functional tool, genius!

Firefighters: Haveing problem with their big pumps Lets print: hold my bucket

Keep doing you dude! I love these types of videos on these topics, there really interesting! I hope your channel grows fast!

And that's a perfect proof of 3D printing usefulness: great for fun or prototyping, but nothing more ...

Free prints are reason enough to thumbs up. I plan to get a printer this year

And you've got a sub. This is awesome.

Would be interesting to see when you attach an pressure gauge to it an see how much it produces Also nice build 👍

Accurate depiction of me in the morning

Consider making the gearbox sealed with gearbox oil inside, this will fix the friction & noise problems. It should run much more smoothly. The oil inside doesn't have to be filled to the top, just to certain level, rotating gears will spread oil where it's needed. Btw. good job!

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

that is so cool, simple yet so powerful.

looks like cooling would never be an issue

Good job. I couldn't do anything that cool.

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.

That is amazing and powerful i realay like it Keep going ❤😊 And i really like ur accent ❤😊

Love this invention you make it's like it's a car And then the car has water in it and water comes out of the tail pipe

Pack the baring between the impeller and your gear box with grease. It will help control the water leak.

Wait a "момент"

Как то дивно смотрится наш клей на канале с англ языком. 1:11

What you had in the back was a pretty nice place to install some kind of "clutch" or basically a spring.

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.
