Double Impeller Centrifugal Water Pump - FULLY 3D PRINTED

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

[felixschafer]

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.

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.

Time for a quantitative competition between all your designs

Imagine what this guy could do if he had unlimited budget and the skills to use high quality machines

I like the Waterpumps, love those videos ^^ Best 3D Printing Channel !!!

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.

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.

Who knew water pumps were so funny and interesting?

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.

Clicked into the video to like just for “press fit” hammering 😂

[MCsCreations]

Fantastic design, dude! Brilliant work! 😃
Stay safe there with your family! 🖖😊

league of legends with a monitor that wide gives you an insane advantage holy cow

[Dom-G-T]

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.

Wait you are trying to say this isn't just the "Water pump channel!?" XD

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.

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?

[Equals]

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.
