In this episode of DIY or Buy we will have a look at peristaltic pumps and find out whether it makes sense to DIY our own version of it or whether we should just stick with the commercial buy option instead. Along the way we will create a stepper motor driver circuit and a suitable 3D print for our DIY version.

For the bearings not turning if you tighten the screws too much: You should put a spacer between the 3D printed cage and the bearing itself. The spacer will make sure the outer rings of the bearings are free, but the inner rings will be tight.

I have some previous experience with pumps like these, the rotary die cutter I used to operate had one for each print drum. The ones we used had the internal tubes connected to fixed couplings to the outside of the housing. Second, since the hoses had thinner walls so the motor didn't have to work so hard to compress them. Third, their were 3 hoses and the rotors were out of phase like 3 phase electric, meaning one larger motor is able to handle 3 times as much liquid. It's been a long time but if I remember correctly, the hoses we're t supported internally on the structure so the rotary would stretch them slightly improving compression. They were held on to the coupling with hose clamps. This might be more than what you need for this but that's more or less how the industrial variety is constructed.

Excellent breakdown of what makes such a pump. It seems that building it from standard components is worth it if you don't have to model (at least not too much) the pump assembly from scratch. I'm in two minds, one side agrees with the diy, but considering the requirement to generate a 3D assembly means that perhaps it's not so clear. Either way I love this set of videos you're making. It's making me ask serious questions about the future of custom making and it's interesting to say the least. Thanks.

I would skip the 3D printer, find some solid material and a drill. For the keyed shaft just make the hole round and use some glue or putty to prevent slip. I would just use a standard dc motor as well. This build is neat, but more complicated than it could be.

That's more true with a good 3D printer and a control system that allows you to turn it on and off without having to plug the cable... mine is a bit of a hassle to set up, especially bed levelling, which is very difficult (I still haven't accomplished it). I'll have to order the auto bed levelling device... I ordered it just a bit too early (there's a new version easier to use)...

Thanks for the inspiration! I made a much beefier version of your design to pump more viscous fluids. On the shaft getting a good fit: next time, undersize the hole slightly and heat the shaft to around melting temp. I just used a lighter for a few seconds. Then slide the shaft on. It's now a perfect fit the first time once it cools. The only negative seems to be slight puckering on the exit of the hole and some cleanup needed for some stray filament. Make sure it's not too hot so you don't burn the filament and ruin the hole!

One way to ensure that the bearings do not get stuck while tightening the plastic holders is to add three washers that are just as large as the bearing's inner ring for each set of bearings. One will be placed in between the two bearings and the other two will be in between the plastic and the bearings. This way, you can tighten the bolts and ensure that the outer ring of the bearing is spinning instead of the whole bearing which can wear down the bolt. Another alternative is to modify the plastic holder design and add a lip or whatever it is called at the hole where the bearings will have contact with the plastic that is just large enough that the bearing's outer ring will not touch the plastic holder. You will then only need one washer in between the bearings when installing them,.

A lot of things are cheaper to DIY when you already own half the parts. I'd like to see price breakdowns by part (bill of materials) in comparison to the cheapest premade component available. This makes it really easy to subtract the parts you have or can make and come to your own conclusions... Though it's not the most entertaining thing to have in a video.

Good video as usual! However, I am concerned with your conclusion, the >500mL/min buy vs your ~200 mL/min diy, the fact that the 3D printed parts and bearings add to the cost and finally the "long life" of the diy is surely uncertain at this point. I don't see much if any advantage of DIYing this pump. What are your thoughts?

The motors does not stall faster with microsteps compared to full steps. And it runs a lot smoother with microstepping. So unless you have a really slow microcontroller it is best to use microstepping at 1/16 or 1/8

Thank you for this, I had no idea such a pump existed - I have been working on a bike with broken steel head studs in the aluminium head that I had started eroding out using alum solution. The problem is that the solution needs to be warmed and flowing, the second problem is that all pumps I have have a steel shaft on the impeller would erode from the solution. This pump type would be ideal for my scenario as the lack of fluid contact with the mechanics is perfect. All other methods have failed to remove the studs, whereas even holding them in alum solution for a while using a rudimentary bath has started the process.

Thank you for your efforts on this project. I grow hydroponic lettuce in my home and looked into automating the nutrient solution mix. This is exactly what many commercial companies use - three to four of these pumps are required required. I found the commercial pump too expensive (purchase + repair cost) so I performed the mixing manually for some time -- and its a daily chore!. I will be using your design when I start the process back up. I have seen several comments that the pricing unjustified your DIY recommendation. For my two cents -- I would consider a one-to-one price match -- still recommending the DIY solution. When you put these pumps into operation (DIY or commercial), they will eventually fail. The cost of repair on the DIY model will be small but the commercial model will need to be a complete rebuy. Thanks again for an excellent article.

Emil Racovita Buy... i never had any issues with those cheap arduinos from china.

I'm going to make one, just for the experience, also to use the PCB sponsors of Mr Scott. But there is no way I could make one cheaper than the clones from China.

Nice work! I once created a standard turbine pump but it comes with a lot of leakage and wear of the parts. This one looks very good. I will try it rebuild it and finally water my plants automatically...

I work at a municipal water treatment plant. We use peristaltic pumps to add liquid chlorine (sodium hypo-chloride) to the water flow. They are self-priming, and they are cheap to replace the pumping tube when it wears out due to cycling, every six months or so.

I found the part in a deskjet printer that I salvaged and was not sure how it is used. Now is a good time to try it. thx for the video

Another great DIY or Buy video, Scott! But I think for anyone who wants to rebuild this project for making the DIY cocktail machine themselves should use food-safe silicone tube. Afterall, you'll be drinking whatever that you'll be making

That's a rally interesting pump design. Reminds me of a Colon.
@victoriamarotosilva7093 5 ай бұрын
You can get significantly higher flow by using softer tube material (like PharMed BPT, which is designed for this very purpose) or by increasing tube diameter. That tube is very important part of the pump.
@zolatanaffa87 6 жыл бұрын
beautiful examination of the pump, congratulations! With a stepper motor you can control the number of revolutions and therefore the flow rate of the pump very precisely, which you can not do with a direct current motor See you next time

Great video, great project. I enjoyed watching. But it does make me appreciate the value of mass manufactured products for people who don't have the technical knowledge , skills or equipment like 3d printers, design software, computers etc

I used to work in a hospital, and we had patients who were fed by Nasal Gastric incubation.the Enteral feeding pumps [ Kangaroos,at the time ] used peristaltic pumps. but they must have had stepper motors, because the food medium [ Sustacal ] moved up the N.G tube in pulses, rather then a constant stream. but the kewl part was that the Pump head, protruded from the front of the unit. so you could remove the cover on the pump to insert a fresh tube when you hung a bag, with out needing any tools. I think they were turn locks, or thumb screws [ Don't remember it was in the late 80's.]
