Description

This is a functional end suction centrifugal pump model. It includes the common individual pump and motor components and most parts can be fitted without gluing. It looks nice on a desktop or workshop . I made most components fit loosely as I broke several shafts with tighter tolerances, and once it is fully assembled the unglued parts hold together well even when spun by hand or with the TT motor.

None of the BOM parts are required for assembly or functionality. The bearings in the model are fully printable and functional making the model spin freely. The motor is only require if you want the model to spin by itself. The bolts and nuts are only used to secure the model to its optional base and add a “real” look.

I used M4 X10 bolts to secure the assembly to its base, but this can also be glued or simply placed on top.

The bearings are 6000 or 10x26x8 but I included printable bearings in the model. Both pump and motor use the same bearings.

The model can be printed with pump only and it includes a coupling hub that works directly with the TT motor. When printed fully with its motor, the motor shaft has a slot where the TT motor can be fitted for automatic rotation of both pump and motor. The motor can also be printed as standalone model.

I also added a simple phone stand structure that can be placed on the base turning the model into an unique phone stand.

The assembly is pretty straight forward. The shaft can slide both ways to both assembly and disassembly are easy. Once the impeller is in place, the shaft locates itself.

The parts that need to be glued are the bearing housing to the pump coupling, the pump foot to the bearing housing, and the flanges to pump casing. The coupled end bearing covers tends to come loose so a little bit of glue holds it in place.

Excellent material! I cut 1/4 of the figure, modified the pump flanges a bit and printed at 200%. Very educational for understanding mechanical components. 10/10

what did you use to cut it with? it looks amazing

I was able to cut it in Bambu with some well placed negative part cubes added. Thanks for the inspiration! This is beautiful

Awesome print. I used the slicer and did a cut away on the pump to see the impeller in action.

I own an electric motor and pump repair shop so it was awesome being able to print one for my office

Super model, thank you very much! I also decided to split the volute casing to see the impeller in action I particularly like the details such as the mechanical seal housing, the shaft sleeve, and the tiny feather keys that even fulfill their function The highlight, of course, is that the machine train can be set into rotation with a motor I only had to file down the claws of the coupling halves to get some play between the coupling and the coupling buffer, but that was no reason not to give 5 stars and boost it

Good design! I thoroughly enjoyed putting this together, as a plant engineer. I think this would be a good resource for newer engineers and other curious folks who don't know what a coupling is or why a frame size is important. I did have a few issues with the prints initially, and while a few of them went away after reprinting, there were a few that stuck around. First of all, the power end bearing guard remained loose. I don't think there's a reason that this couldn't be designed with tighter tolerances, although the instructions did call out that it could be glued in place with no issues. My biggest gripe is with the motor, and how delicate the fan blades are relative to the force needed to install the fan on the motor shaft. Maybe making that part of the shaft a bit narrower would avoid that issue? That was the one part of the build that the instructions glossed over.

Thanks for printing and for the feedback. I'm glad you enjoyed it. I also enjoyed assembling it myself and have it displayed in my office and use it for similar purposes. Can you please elaborate on the printing issues you had so I can improve the model? I actually printed it several times using a P1S and A1mini and didn't run into any problems with the components. Yes you are right I could make the bearing fit deeper into the housing and increase cover lip depth so I can improve the contact area while tightening the tolerance to reduce the need for glue. I could do a print profile with those changes. With the fan I actually left the tolerances tight on purpose to ensure the fan stays in place when the shaft is rotated avoiding any axial movement. Unlike the impeller that is held in place by the casing, the fan would spin out of the shaft. since the fan cover is just lightly secured to the motor frame I should have included in the guide that it is probably best to tap the fan into place via the hub to avoid breaking the blades similarly to how the rotor is installed on the motor shaft. I'll look into it. Thanks again!

I work at a pump company was thinking about printing this for the owner’s desk…curious if it’s fully functional.

The designer has replied

@user_2688543725

Do it, I'm glad I did! I also work for a pump company and everyone loves it, including all the old guys who have never seen additive manufacturing done at home. Now the owner wants to buy our shop a 3d printer and scanner so we can explore printing parts band aid repairs or anything else we think of for work. Basically, it's a fun project and started some cool conversations that led to new ideas!

@cralvz

Replying to @user_2688543725 :

Thanks for the reply and yes everything is indeed functional ! I'm glad it opened up possibilities. Nothing like tinkering!!

@CptDadBod

does the shaft actually turn the impeller?

The designer has replied

@user_2688543725

It does, they're all connected with the couplings and the shaft keys.

@cralvz

Replying to @user_2688543725 :

Thanks for clarifying !! yes it does turn as mentioned!

@user_2278510032

Excellent model. I would like to print and use this at my work to discuss pump parts and design. Not being a lawyer, the licensing agreements are tripping me up a bit, primarily the terms such as "commercial". Would it be ok to print and use this at my place of work to use as a demonstration piece but not to sell the printed model? Thanks in advance.

The designer has replied

@cralvz

Thanks. I’m glad you enjoyed the model. Yes of course. I use it for similar purposes at my work so I tried including all the main components. the license is against commercial use meaning that you would make money off the model or sharing the digital files or re uploading them somewhere else, but you can use the model personally how you see fit :) enjoy!
