I did it again x2 and the results were satisfying. A double impeller centrifugal water pump is probably the most powerful water pump I have ever made.

This is a certified "rigid flange coupling" moment
Estonian language moment
Tom?
That voice was terrifying 🤣
Just to clarify, this principle effecively can't make(much) more pressure than the single Impeller version. The two static pressures of the Imellers are pressing against each other.
To generate a higher system pressure and don't want to build a multi stage pump like a KSB Multitec, you need two pumps in series. The second one has to be slightly smaller to compensate for the lower volume flow.
Mmm tasty knowledge snacks.
Two pumps in series is lterally a multi stage pump ! Also the impellars should be swapped as they are backwards. If the water flows down the curve from the centre outwards it should be directed toward the exit with it's inertia helping rather than stalling & being squeezed against the plenum.
but then it won't look like balls anymore
@@chrisharvie-smith486 they aren't backwards. The vanes are supposed to be swept back with respect to the direction of movement. It's called "backsweep"
Gracias por apoyar a quienes estamos al inicio del camino
I would love to see a constant water supply to the pump to keep the water level just right. Then a side by side comparison of the pump flow and distance compared to a garden hose.
It’s funny (and to me, endearing) how much your English accent sounds like that of Finnish people. I knew of course that Estonian and Finnish are closely related, but I’ve never been to Estonia yet-I guess I really should! I love Finland, and I might just fall in love with Estonia as well.
Great job on the pump. I got quite a chuckle out of the "press fit" text overlay and the "rigid flange coupling" audio insert (and callback to previous episodes). Well done.
such honest videos i love it keep up the good work!
its good to see you again
Fantastic design, dude! Brilliant work! 😃
Stay safe there with your family! 🖖😊
I bought a 3d printer specifically to print this and now I realize that the files aren't available 😅
Thanks a lot for all these pump videos. I do a lot of prototyping, and buying various pumps gets expensive! Much appreciated.
I like the Waterpumps, love those videos ^^ Best 3D Printing Channel !!!
Time for a quantitative competition between all your designs
Really enjoy this channel
Imagine what this guy could do if he had unlimited budget and the skills to use high quality machines
Use some silicone on the flanges of the cover before installing and it should take care of the glue need. Looks like it would make a good proportion system for a small water craft.
You should test out water jets, they have really high flow rates over 100l/min in most cases one adapted to be used as a pump would be awesome.
lol, Rigid flange coupling...love it
I like this design. It seems to work well! Given the material I wonder how long it will hold up. I'm thinking about trying to 3d print a pump for my aquaponics system and may reference some of your work
Who knew water pumps were so funny and interesting?
Lol looking forward to it
It looks like a set of eyes
You could add a 'wet' cover over the gears to stabilize the ends of the axles and limit the splashing back toward the electrics. Are you using high end bearings like ceramic?
that ryobi drill must be exhausted
Those gears stop pretty quick, maybe you should create a housing and put a light oil in there, something like a 0 weight? Could help make it run faster and help protect the bearings.
league of legends with a monitor that wide gives you an insane advantage holy cow
A T handle Allen set works great ti get in tight, long Allen keys, screwdriver extentions, socket extentions; no need to make your life hard.
I like the videos, as learning tool for my kids.
We home school.
would sure love to see 3d printed hydraulics and a valve body.. if you're up for it and maybe a positive displacement pump while you're at it
Time to start BOOOOOO-EELDING
You really need to start using some rubber seals on to get a better vacuum on those pumps. I bet if you closed off all the air gaps you'd have at least 12m throw on that pump of yours

My children and I watched to see
1) how does it work
2) what science and math is applied
3) how could it be made better
4) where would this type be used.
As i said before, we watch for education.
These said;
Mersadies) gear cover would have been nice.
Leo) you dont seal good enough
Ryle) likes your ideas, and wants to learn how, and he needs to add switches and fuses. Electric and water is bad.
We all love your videos.
Me) maybe centrifugal disk pump video.
Clicked into the video to like just for “press fit” hammering 😂
idea, why dont you mount the tub to a raise surface, then print an intake coupler, somewhat similar to the way turbo manifolds end in a standardized flange, just .... your own lol
Wait you are trying to say this isn't just the "Water pump channel!?" XD
I would expect this double motor to be able to work with a smaller nozzle for higher pressure and larger distances on the spray
I notice you use the grid infill pattern for almost everything, what's your reasoning behind that? BTW I love these videos on printed pumps, keep it up 👍
Maybe you could build a multi stage centrifugal waterpump 😁
magnetic gears would be great to see, like that the water can't leak out anywhere where it isn't supposed to
It would be interesting if you try to make a turbo bomb like the one in the rockets hehe
How many watts does the motor draw with the pump?
So now that you have become the impeller man you should try a supercharged or turbocharged pump maybe both and you could see which is better
Can you design 3d printed pump for pumping viscous liquid like engine oil? Also which with small out pressure
soo in conlusion what you finde in comparation with multi stage pump? In paralel give more flow?
Instead of using gear it's good to join both the impeller back to back
No more water pumps!? Does this mean the end of rigid flange couplings?? Say it ain't so!
Ah yes, the water bump!
How do you insulate the shaft ?
i understand you what it means to be addicted to LoL AHAHAHAH btw if you want to do a duo come times i m here ahahah
you don't need to waste filament on rafts if you use chamfers on the gears
"That metall somth" is good, noone knows its name. I also liked the joke with flapping pinguin long ago... A little humor is a good feature of your channel. Good luck! And how long is a season when you can experiment outdoors with water? Here in Russia it will freeze soon and is freezing in some regiouns... Actually it does not melt ever in some places here.. Ehhh...
Time to migrate to Prusa slicer for the supports
you should add a second motor
Where did you get those absolutely essential motor shaft adapters shown at 3:37?
You mean the *RIGID FLANGE COUPLINGS* ?
@@GuyFromJupiter Now that I know what they're properly called, I can find them. Thanks.
What application your using for 3d drawing and simulation
Print a self priming pump.
press fit
impact pressing I guess :)
Last one of the year vane pump??
This will be a hard one for 3D printing, but I’d love to see it!
@@BRUXXUS I've made a few actually! Suprisingly easier to print than you'd think! I managed to make over 20
psi on mine before the shaft stripped out from the rotor assembly.
@@Only1Sethy No kidding? That's impressive!
@@BRUXXUS yes sir! Let's Print said he was going to make one, can't wait to see what he comes up with
and now put it on a boat ;)
Waiting for links🤯
making water bumps in your garage too spray the neiboughs cat
So much friction. Maybe check your tolerances?
Would you be interested in designing and building a electric linear actuator, after your obsession with water pumps has ended? 😊
I would do it myself if I wasn't so damn lazy.
The pump should not have a gear wobbling sounds but okay.
RIGID FLANGE COUPLING
1
2 gears 1 pump (gone sexual)
Man, it internally hurts me to see you exposing bearings to water
I often end up having to use a glue gun from similar reasons. It's very frustrating.
lol
nice stream
impeller pump edf
You are gonna stop making water pumps? Dude... leakin... eh... i mean... exceptionally performing water pumps that were moving water from different sides were the cornerstone of your channel, the reason we all love your videos. Anyway... i was wondering when you design gears do you make any calculations for the mechanical stresses and the type of gear that you are about to use? Also it would be nice if you could make a tutorial about gear design, size, total number of teeth, friction, etc.
Hindi nhi tujhe kya
Nice but totally useless.
???. Abomination
go learn English lol
YOO A FELLO ESTO!! Elan USA-s, aga seal, kus ma elan, pole palju eestlasi. vabandust kui mu eesti keel on halb, saan harjutada ainult ema ja õega
