One interesting pump design you could try ist the mazda rx 7 oil pump sesign. It should create a very high pressure.

You really stepped up your editing game, humor is on point as well

i would actually love if you were to benchmark them in a few ways and compare them in things like static pressure flow rate or maybe even a plot pressure vs flow or something like that ... but comparing the designs and maybe even trying to improve them

The advantage of this lobe design is the lobes can have more clearance so you can have wider tolerances. The volume of water on the outside is far greater than the space in the middle, making the forward pressure far greater than back pressure. I was happy in the last video when you said you were moving to this design.

The whole benefit of having much longer gaps at the housing nullified by the very bad gaps at the profile engagement. It is true that a longer gap decreases the leakage flow. But with this design the profile engagement gap not only is much shorter there even is a dead volume being transported from high to low pressure like you can see at 2:06.

Congratulations on 100k subs! I’ve learn many things from you about 3d printing. Keep up the great work!

the editing and comedy are great. You've come a long way and I am glad to see your channel has grown to the extent it has, keep up the good work.

This channel will pump you up! Gratz on 100k subs.

That's one part of his lawn that'll never be dry again

Congrats on 100k! Love your content and playful attitude :D keep printing!

It would be cool if you could test both pressure and flow, because those are very different and different pumps have different flow/pressure ratios. Just because the water doesn't spurt out as far which you deem as "performance", doesn't make it a bad pump. It just has low flow and possibly high pressure.

Such an awesome video. Exactly the type of inspiration I need to start doing this stuff myself!

It's looking so good !

how about a rubber sheet to use as a gasket instead of silicone? it'd be easier to take apart, and can be reused if you're using the same housing again. have you thought of trying a screw pump?

You worried about the leak from lobe-casing contact so you create a wing shaped rotor to maximize rotor-casing surface contact. By doing that you reduce the rotor-rotor contact (in the middle), which is more important because the gap was pushed into the inlet.

Hell yeah! great job on this

I’m glad the wing love pump came out! I’m so proud of them

Great video!

Use thousands of dollars of equipment to manufacture a pump of unknown head, capacity, lifetime, efficiency, that you could probably buy for less than $100. Winning!

Looks like a good volume of water coming out :) I am curious what happens when you add a small nozzle, like a power washer.

The best quality I have ever seen yet his print literally literally looked like garbage. That was definitely a promo for that machine. You really need to fine tune your 3D printing skills dude.

Your editing and meming skills improved alot and i love it. Hilarious 😀

I was puzzled as to why the wingless on performed better, and it seems to me that the front wings force the water backward at the end of each cycle. Eliminate the leading wing, and you may be onto something.

what the fuck is your accent, it's james-bond villain levels of awesome

nice project!

Congrats, very clever, love your channel 😎

Very interesting. I just stumbled on to this channel. I like it!

i love the classic editing of the video's... brings me back to the 2017golden age of youtube ❤

All ways fun videos to watch, Love how as the video images of the pumps fade you see smoke from the gear box.lol

amazing video editing. bravo.

I got to you the best idea ever, copy the fan showdown but for waterpumps, people loves to participate

Animations, script and effects were hilarious! :D

Did you see the "magic smoke" coming from the Motors at the end :-D?

Best video yet

Greetings from America; I love your dry sense of humor

Congrats with your subscribers count, let me bump that number one higher for ya.

Thanks for showing me that bambu printer! Seems like a very high grade machine :)

Have watched a number of your water pump videos, just hoping you will read this comment. I'll suggest looking into iglidur as a material and iglidur filament, the FDM printed gears will benefit greatly from a material swap, you can just print the infill in another cheaper material if you have a multi-material printer. It will generate a lot less friction and yielding better overall

It’s a pretty standard waukesha sanitary pump design and they have issues getting primed if there is significant wear between the rotator and housing The clearance will generally become the size of the biggest abrasive particle it’s pumping

Just subbed! Let's GOOOO

10:25 😂what did that go-pro do to deserve such a waterboarding 🤣

This video randomly popped in recommendations. Thought what the hell, was impressed with what i saw, then i notice you were using Ryobi tools. Oh the humanity!

i like ur style of doing things

what do you do with the old plastic because it seems like a lot of waste I never owned a 3D printer before one of the day I love to get one

its everytime nice to see your pumps :-D maybe you can make longer videos with some use case of your pumps

Pcbway, that's a helpful company to know about.

That printer is insane

I've been paying attention to your vids for some time. Ur awesome ! I'm also obsessed with pumps. Your CGI animation & description of why lobe pumps work was REALLy cool. Perhaps I can add to the understanding of why pumps pump. I'm hoping to expand your understanding & it might help you to make even better designs. The notion of flow between high and low pressures is correct, but it is less relevant here. It is less relevant because water is not very compressible. Ancient man would say water is not compressible... Thus, when we think of water pumps and the reason they pump, I like to think of it like ushering the water. Escorting the water. Pushing the water. Think of it like chambers which change shape. The changing of shape means the water will flow when the volume space is altered. In the lobe pump, the changing of volume occurs when(in the middle) one lobe enters the space. When the lobe enters the space which has water in it the water is pushed out. When the lobe leaves the gap, water goes in to fill the gap. The gap is the space in between the gears... or in between the lobes... Hopefully this gets your mind gears turning... Your mind lobes, lobing... -Cheers

What program for you use for the modelling and animations?

100k! Woo-hoo!! 😁

I always like that he is never paid to say anything. 😆

so which of those pumps is self priming and both direction and which moves most fluid?

I would love to see what kind of pressure these plumps can generate Out of a 1-2 mm nozzle and static could be cool for a simple hydraulic arm

Gracias por invitarnos a tu hogar.. I really appreciate it.. Greetings from Costa Rica, your videos are simply awesome..!!

That camera in stream of water, would be cool if it was livestreaming. 😏

I understand your pain , what a wonderful world would it be if we could just 3D print a sturdier material , like man the amount of time saved and the progress that makers would make would be INSANE …… fever dreams 😢

I will Subscrive to your channel because I know the feeling of scrapping supports for a long time :)

the editing is insane my guy

Most people: pump👶 Me: *W A T E R S U P E R C H A R G E R 🕶️*

It’s funny you pronounce build as BOO-ILD hahah i like it

Nice Design. I would love to print those things, too, but i don't have a printer. As you get sponsored very well, i kindly ask you for a spare printer of yours, which you don't have any more space left for at your home. I would take care for it very well...

Hahaa, ma teadsin et eesti aktsent (kuni lõpus YT statse näitasid) :) Lahe video, pull kanal, ei teadnudki varem su tegemistest midagi, subscribed!

i use these pumps all the time at work

"short story long" also "shit story short" -This adequately describes my life . Lmao I love this dude. (╯°Д°）-o--|===> /(.□ . \)

I downloaded the file but it downloads as a step file. Do you have the STL file?

I was surprised that the water actually goes around the outside edges of the blades inside the chamber rather through the middle of the two blades for a straight shot through the middle of the chamber. Edit: I just read someone else's comment saying it's basically because if you were to run it so the blades push from the middle instead of the outside edges, the two blades would be slamming water from the outside edges of the chamber (with more volume of water behind them) right BACK into the inlet and causing more back pressure than forward pressure

You should try an impeller pump next, they're much more forgiving to build and can still generate some decent pressures.

seeing u going ham at those bearings with a hammer😢

I am not paid to say this but Damn that thing pumps 😂😂👍

11:32 Magic smoke is starting to appear.

You should use radial shaft seal with grease like in washing machine, and also two bearings for each shaft - on both sides of gears.

Lobe pumps are usually used for pumping oil, other liquids damage the pump prematurely! Also what is the brand of the green soldering iron?

I totally clicked on this because of the cool pump lobes in the thumbnail.

Keep up that broken English humour. It’s on point and very entertaining.

Пытался избежать обратного тока между ротором и стенкой, а между роторами теперь огромная камера для обратного тока😆😆

Is the animation backwards? Because the shots of the physical unit are going the opposite direction... 🤔

Have a look at the old Johnson IC30 or new Wright pump MP range. Tri lobe or bi-wing lobe. Look at the gearbox side. Try an additional set of gears further back in that "empty cavity" you have. it will balance your shafts and give more stability at the end of the lobes. At high speed your lobes will be moving up and down with such a thin shaft. Just a thought. Excellent work, love the pump vids!! (also, max rpm for any lobe pump should never exceed 850 rpm at the lobes)

You should have already designed a symmetrical gear set where the number of teeth are divisible by 4 and align the four mounting holes in a simple square in a way that the holes would line up with the peaks and valleys, alternating. This way, you wouldn't need different design for the gears, nor the rotors, you just have to mount whichever one 90 degrees off. Second: shaft seal: Isn't there any rubber + spring type seal there? I don't know it's proper English name, I've seen them mentioned just as shaft seal everywhere... Those press-fit things like bearings. It'll provide better seal with magnitudes lower friction than O-rings. Lid seal: Just use rubber sheet or big O-ring with a groove, but even when you just use sheet gasket, it would improve the seal if you add grooves to the lid and matching "bumps" the other part. The rotor clearance can depend on the gasket thickness which is good and bad, it depends. Bad, because you have to set the clearance, good, because you can set it. If you don't want that, rather print exactly sized parts, then just don't use the flat surface to seal but create a taller housing and a lid that slides into that, then use the circumfence of the inner step instead for sealing with an O-ring in a groove. I'd like to mention that for an O-ring groove it is better to use square profile, not round. The rubber has to go somewhere when you compress it, and if you use a square profile there will be 4 corners for that so you can make a quite tight fit while still be able to assemble it.

Test this as a hydraulic motor. You use a hose to put pressurized water into it, and the shaft turns. Also, test the pumps ability to raise water to a higher level. Connect a hose to the pump outlet when it is in pump mode (as shown) and raise the hose outlet to the roof of a house and see if it will lift water to approximately 20 feet.

What 3d design software do you use?

I know this isn't really in the scope of this channel but you should get a CNC and make stuff like this out of aluminum (or print a CNC?)

Interesting

what about using camshaft or crankshaft gears from a car instead? i feel like they'd give you a lot less resistance to make it spin faster and move more fluid

Have you thought about gear lubrication? Using a light weight oil should help out a bit.

this is so cool. I am confused though about the flow and pressure zones. If it flows from high pressure to low pressure how come in the graphic you show it flowing from low to high? If that makes since

Oh boy! At 10:00 he turns into a savage! Awesome 🤟

Voids in the return cycle is causing the efficiency to drop. Forcing some of the water to recycle through the pump.

Does it work in reverse?

It would be interesting to see what a piston hydraulic pump gear would do compared to a Marzocchi pump gear like they use on the lowriders to make them hop.

What's about a screw-type pump like used in air compressors? I woul love to see one of these 3d printed!

I am curious if the water seepage between the rotors and the walls could be minimized by incorporating a Tesla valve in to the print?

I think you must try sliding vane pump. Just this type is good, but needs a lot of power.

Try an aviation fuel pump style which are rated for 2-500 gph. It has off center cage that uses a solid front and rear bearing the impeller consist of rotor, blades, and center pin which have tolerances but move in eccentric fashion to pump. Bearing are center but cage is off center so when the blade reaches the close tolerance side in compresses. 4 blades are necessary.

Apparently each piece was printed in a different printer

I love the design, but in the center of the pump where there is a gap, it will create a compression that will reduce the pump speed.

aka batman rot- THE CUTOFF XDD

Tell me how to make herringbone gears

6.2.1 is good for X-Plus now and you will love the supports!!!
