This centrifugal water pump is the best water pump I have ever designed/built/3D printed. The secret behind this insane performance is the closed impeller, usually, these DIY water pumps have semi-open impellers that arent soo efficient.

New movie: "The Rigid flange coupling"
i chuckled each time!
Rigid flange coupling: the dungeon master
IN A WORLD where everybody's 3D printed water pumps have leaks, ONE MAN has the solution, RIGID FLARE COUPLING
FINISH HIM!
Hahaha I heard "Ric Flair Coupling"
For such a talented and gifted designer and creator, you make the world's worst field tests!! Although they are funny to watch, so bonus points for that! Great videos, thanks.
As my colleague said: "You don't neccessarily need to be the best rc-pilot to design best rc-models".
I think "my new design destroyed my test setup" is certainly a great example of the meme "Task Failed Successfully." Love this video!
Everyone starts somewhere. Think about the rigs this guy is going to be operating when he's in his 40's.
you can use a ceramic bearing for the shaft. They are not god for impact loads but they are rust proof and dont need lubricants
And usually lower overall wear/work better as high speed bearings too!
should be easy to find as well. they are common in pool pumps
@@HDDRecovery can find them on ebay pretty easily.
i can find them broken at my workplace.
i must have over 50 ceramic ball bearings in a bag that i picked up from the floor at work. we only spin them at 10 rpm but any debris and they bind up and blow up.
its a common consumable there. i dont know how many maintenance has to replace monthly but its never zero.
@@darkshadowsx5949 well being that these will constantly be washes by the water in the pump, i doubt debris would be a problem, just make sure to remove the seal on the inner side
A flow meter to put some actual numbers on the pump performance would be awesome
Nice, for next version, you may try a logarithmic spiral for the volute shape instead of the linear spiral, Physics say it should be better, something about constant angular momentum for fluid elements along the trajectory. Glad you are taking care of the leaks problem better now :)
Sweet build. I work on pumps for work and all of the pumps that I work on, have the shaft seal on the inside of the pump. The bearings are inside the motor which is outside of the pump. There are no bearings inside of the pump. The shaft seal faces ride against one another. One has a ceramic face and the other has a graphite face. Half of the seal mounts to the backside of the impeller, in a recessed area for it, and the other half is pressed into the pump housing. Keep up the great work though! Loved this project!
This blew my mind. Graphite makes absolute sense considering the shear strength of the atomized carbon is actually going to be significantly higher than in any oil. I've never thought of using graphite for high pressure, high speed application, but with this explanation and the knowledge we have of "graphene" it makes a TON of sense. I wonder if using a material that not only was dense, like ceramic, but also repellent to carbon in chemistry could improve wear. The simple solution of graphite seems almost unbeatable though.
@sourand jaded carbon mechanical seal faces can get particulate embedded in them and will cut and ruin the stationary face they run against.
@@SpadeNya carbon is used for its self lubricating properties. A carbon rotary running against a silicon carbide stationary is the coolest running face combination. Alumina ceramic like mentioned in the above comment is a poor conductor of heat and will create a condition called heat checking if not kept cool. Other materials used for faces are antimony carbon, sintered and reaction bonded silicon carbide, tungsten carbide, PTFE, and in some cases chrome oxide plating. Most smaller pumps with shaft diameters below 1.500" use cheap throw away seals from the factory which are around 300 dollars. Larger pumps will use more expensive cartridge mechanical seals that can be rebuilt and can range anywhere from $1,000-$50,000 depending on size, metallurgy and elastomers used for a particular application. Sorry for the wall of text, I have a lot of experience with process pumps and rotational shaft sealing and couldn't help myself. Lol
Hey, new here but as a automotive mechanic I think I might have something to add. When you're installing shaft seals, you want to install them so that the pressure they are supposed to contain presses against the sorta V shaped wiper that seals the shaft. This makes the seal use the pressure it is supposed to contain as pressure to keep itself sealed. At 2:42 it looks like you installed the shaft seal backwards vs what I described, which is a pretty common mistake people make with crankshaft seals in engines as well.
Cheers.
I really like your accent in your videos. It makes them unique
That bucket filling footage though gosh that is one aggressive pump 😆 Seriously nice work! & thanks for sharing the files with us.
Your video is so entertaining because you leave in the mistakes. Your comedic delivery is great!!
so the reason this worked so much better than other pumps is because pumps are extremely sensitive to impeller to housing clearance, and this sensitivity becomes more and more important as you make the pump smaller. The enclosed blades are basically like a perfect fit; the housing in this case still matters but its easier to add more area to it to get a better seal with poor tolerances.
You should make a hydro dynamic bearing for it arround the edges of the impeller to seal it and clean up tight tolerance (with grease oil or water) love the vids
Or with pressurized water
Nice
(The impeller to housing tollerance will be great)
Great job! No fakes here folks, if it leaks, it's the real LPO - lets print original!
Brilliant, dude! Really fantastic work! 😃
Stay safe there with your family! 🖖😊
I don't know if you've tried using TPU printed gaskets for your pumps but it's something to think about
I've printed a few gaskets with TPU, and I found normal 95A TPU to be a bit too hard. Probably the much softer filaments, 70A and softer, would be better for water sealing, but I've heard they're difficult to print.
@@DisorderedArray i print gaskets with Ninja flex (TPE) 85A. works perfect. printing them 1mm thick
@@BlueEyesRageTv good info. Is that on a boden or direct drive?
TPU is a flexible plastic but not a soft material. Image a TPU fleshlight ! impossible..
@@DisorderedArray Direct drive. Can work with bode if you print super slow and no retraction. It is much much easier to print flexible if you use 0.6 nozzle or bigger. I use 0.6 and it's perfect. I can print with 0.4 to but then i need to print slower.
Best design for water pump that I’ve seen yet! Great innovation
Man, you are in top 3 channels for 3d printing because, i like that you TEST and SHOW NUMBERS of everything, thats so important, and making the reviews versions and sharing your process of thougt, cut the youtube bullshit by showing numbers, almost everything is pure numbers (sry for my english)
Man uses TTS to cover gaps in his English. King.
Wow, you made huge leap forward in efficiency.
Wow that is amazing work my friend. Genius! Beast mode pump
The amount of respect i have for you is immeasurable
Very nice pump! Definitely your best pump yet! An idea for this, try to make a large diameter intake pipe so the pump can stay flat and suck in the water.
OMG Dude thats epic. You have learned so much. That thing is a beast!!!
After 8 days i ask for the model again! Nice pump! Thank you.
Nice Work. Can't wait to see what you do next.
Nice and smooth Bruh 👍
Nice :o these keep getting better and better
Well done mate, I've been following your progress on these pumps and this one is amazing.
We need beer Dan
@@kanal685 We all do mate, 1 pallet has been sent out to you and should arrive shortly.
congrats!! you did it!!! okay now make it as big as you can! hahaha
Omg it looks so much powerful right from the intro 👌
Amazing project
I'm so glad I came across this channel. Really interesting stuff.
That's a dope ass tub
Well done!
That fellah sure builds a mean Bump!! lol
Great vid! Kinda got me thinking if the pump can be scaled down like 50-60% and made into a really powerfull water gun :)
next time please do an insane air compressor !
Your videos crack me up!
Keep it up.
A very impressive design especially with the gearbox fitted that shot the water so #$%#* high up.
You are awesome man! I really like your 4 motor gearbox.
Great video! Throwback to the horrors of Turbomachinery course during my ME though 😂
I worked for Pentair and this is how they already make water pumps.
Another great video! Would love to try this design at our nearby creek 😉.
Great pump mate, I'll probably steal it and use hydro bearings so I can use it as an aquarium pump.
More important. Pressure and pump heights. What are most pumps used for? Pumping from low ground to higher ground. Volume will always be second priority 😅 any other engineers agreeing?
I disagree because it entirely depends on the application. some pumps are made for static pressure, some are made for flow rate, and some are designed for a combination of the two. Saying "volume will always be second priority" is a glaringly shortsighted perspective on pump design.
3:55 Another option instead of hot glue is to use a 3d pen with the same filament I printed with.
Alternatively you can use a solder iron to stitch the gap by dragging material from both sides!
_"Rigid flange coupling"_ made me laugh as my missus can't stand hearing *_gusseted flange._* Some people are very strange, lol.
love these projects. For some reason the "R I G I D F L A N G E C O U P L I N G" had me rolling 🤣
You handled pretty well the Achilles' heel of "The rigid flange coupling"!
What about it's sucking capabilities? Could you attach a hose to the other side also and check if it would suck water from one meter?
I have the bell notifications on for everything you upload,but i never got notified about this video, that's super lame. I absolutely love your videos and they're super enjoyable for me to watch and learn from
@8:11 looked like i was getting flushed !! hey great video dude, i love how candid you are and how janky your tests are, its beautiful. ALSO you got my like for RIGID FLANGE COUPLING! :)
Nice! I did the same for a bilge pump a year ago and Oh Yeah! From 2000 to easy 4000 GPH and real pressure. Keep an eye good prints, pressure may crack your housing.
I love your videos!
Have you tried printing the Impeller INSIDE the housing? i.e. one print?
Sure you might need to change way things are mounted, attached, make some geometry changes, etc. But it might help reduce sealing issues.
Managed to print impeller in my design "just above" the inside of the housing and was able to separate it fairly quickly/easily.
I think two of those on the back of a mini-boat / dingy would get it going!
Do you have the stl files ready to upload to Thingiverse for this ? I would love to build it.
Awesome! Tip: with the S1 Pro being direct drive, that should also make it easier to use TPU printed gaskets instead of hot glue ;)
now you need a small boat or jet ski to test this pump on.
probably not going to fly on it but you'll see how much power it has.
This is cool, i'm trying to build one, but what size are the shaft and bearing/seal? Thanks!
I have upgraded my V3 over the years to the point where it's basically an S1. The Sprite direct drive extruder makes a big difference.
would love a full vid on that s1 pro
Would you print one of those laminar flow nozzles and attach it to the outlet.
I'm curious as to if you'll get laminar flow or if you need to have a tube between the pump and nozzle
i like how your pumps improve. just get a bunch of small mechanical sealings, its what used in pumps.
Reminds me of the pump I seen for a motor surfboard.
i was thinking of using this as an underwater brush, the brush being attach to the shaft and the motion being delivered by an electric pump that will suck water thru the housing... do you think it could work?
you should try to turn one of these into a self priming pump
That's a nice Water Bomb!
I can't focus when I'm laughing so loudly:)
put a thin bead of hot glue down where your housing joins together. This will help seal the housing and increase the pumps pressure.
That's the correct geometry due to the rotational force creating an outwards induction on the supply force out it's energy😅
Great video. I liked how you described the design changes as you went. Suggestion: the outer housing seemed to be more beefy than needed. I would try to make the outer housing walls about half as thick to use less material and make the printing process go faster.
Btw grate choice in drill...it's the only compiny with revers compatibility as a staple...so you will always find replacements or new stuff working with old...no other compiny in tools dose so
Great video! "Rigid flange coupler"😂 i also liked " looked like shi--was not perfect"!🤣😂 very cool design though! Im not an engineer but i wonder what its practical uses would be for things other than pumping water🤔 ive got to get a 3d printer one of these days and try out some of the cool designs like this one for every day uses! Cant wait to see your other videos 🙂
We turboing water now
It's fantastic
We're I can find the stl file ??
Thanks for share
Have you considered fully ceramic bearings?
look up any fire industry centrifugal water pump. They are of this design. Downside to the design is they can collect sediment in the vanes if they sit for a while. You can backflush the pump to regain efficiency losses. This design is how its done.
Piss myself laughing every time I hear rigid flanged coupling 😂😂😂 Great video! Every man's secret desire is an efficient 3d printed water pump 😆 Thanks..! 👏
Nice. What motor and power of motor are you using?
Put the pump in the bucket and see how long it takes to empty it.
You should buy a flow meter that attaches to a hose for these tests
can we get a video comparing each pump's pressure? like see how high up each can pump water
How much air (drone airplane thruster) it can move, gear it up
What size bearings did you use?
Attach the rigid flange coupling to a horseshoe thingy for better performance
How strong is it if you use a battery powered Drill? For example i have 60l Container
7:39 super sciency and exact.
For exact figures and numbers and to know in seconds exactly how many litres.
Great job love your channel, if you could share the files in step format it would be perfect!
What was the DC motor you ended up using?
You should try putting one planetary gearbox in it
This man has been working and testing the water pump for so long that his grass has grown green
Lol
Hello, nice design. You could use closed bearings, they're for fluids etc. they cost about the same. Regards
Nobody talking about the smoke at 8:46
I used to machine IRL impellers and some would be 4-500mm diameter and go into a 4-5 stage volute split housing... the power draw must be immense
I feel like you’ve done a ton of free impeller pump R&D, and somebody some engineer is probably using this info to coast for a bit
Hello, how many liter per minute can pump ?
Do you have the stl to download?
You need some rigid hosebucket coupling
Make a version of it that gives you an easy way to connect a hose onto the intake.
