I know this video is a year old, but thank you for showing us the real life pumps, along with the 2D animations. Seeing both at the same time was very helpful, yet no one ever does that.

i know im randomly asking but does anybody know a trick to get back into an Instagram account?
I somehow forgot my login password. I love any tricks you can give me
5yrs now. Lol
Unless all of these were in your back pocket, This was an expensive video. Nice job on the explanations.
I have to assume that his back pocket is full of all sorts of random ass heavy equipment that makes his videos a bit easier to put together… Nonetheless for someone who likes collecting random knowledge like me it’s a veritable Gold mine
Good video, excellent presentation. Still, I have a few suggestions if you ever re-do this one.
1) Mention at the start what "positive displacement" means and how that contrasts with other types (i.e. why you would want to choose a positive displacement pump)
2) On the plunger pump, you mention that the "physical mass" of the plunger creates the change in volume of the chamber. It can't be mass, it must be the physical VOLUME of the plunger.....
3) For the peristaltic pump, I think it would be good to place greater stress on the point of the pumped fluid never touching the working parts of the pump, and thus the pump cannot be contaminated by the fluid, corrosive liquids can be pumped, the pump mechanism cannot contaminate the fluid (thus good for certain food and medical applications), etc.
i agree, when i worked on an offshore rig, we used several different pumps to move fluids around.
i learned that centrifugal were great at moving high volume but lower pressure fluid. Can be used to pump fluids with small amounts of debris but cost more if it gets damaged.
we used PD piston pumps for high pressure stuff but they needed big motors to drive them.
we used PD diaphragm for pumping small amounts that had debris in it because they were cheap and very easy to rebuild, and pumped trashy fluid better than others. A kid fresh out of high school can be shown how to work and rebuild one in a day . i suggest this one for shops over centrifugal.
I was about to comment the same as your point 3, I'd never seen peristaltic pumps before I started working in a chemical lab. Being able to keep moving parts entirely out of the flow is a huge advantage for maintenance, purity, and consistency.
@@johnstonefield1935 That point 3 is also the reason why they're the pump of choice for heart-lung machines and dialysis machines.
This is exactly the kind of video I was looking for. In depth enough to have a gradual understanding but short and sweet enough that it’s not boring. Along with having 2D and real life models to match. Easily the best explanation video I’ve seen.
This is your daily dose of Recommendation

This was very helpful. Thank you for showing these real life pumps. Professors don't do these. They just put diagrams of these pumps in presentation.
Wondeful. Straight to the point, simple explanations with easy to understand models. No shitty music. Absolutely wonderful, thank you very much.
As someone that has been building/rebuilding industrial process pumps for over 10 years I can say that these videos are better than anything any actual pump manufacturers have. It's nice to see fluid transfer get some love, you see fluid power more often. Not that hydraulics aren't important.
An interesting outlier on the PD pumps would be a SINE pump. You don't see them very often but they have their place.
In dealing with all these pumps, speed reducers, belt drives, couplings, VFD's, and everything industrial; one of the most interesting things I've come across is the Cycloidal drive reducer. I'm sure you have more suggestions than you can shake a stick at, but this would be my suggestion.

This is a comprehensive pump explaination, your combination of real pump and animation help me see it working principal clearly. You did an awesome work, thank you very much.
This video is beyond amazing, this is the first time I'm coming across your channel and I just can't resist subscribing. Just beautiful, thank you ❤️🙌🏾
Awesome videos Adam! In 4th year millwright and you cleared up a lot of mysteries for me! Thank you! Keep them coming !
Came looking for PC Pump details, not much more here than had already seen. BUT, what a fantastic video! I definitely left smarter. Thanks for your time!
Thank you so much for sharing this great video with us! It feels way better to get an idea by watching real-life pumps!
Fabulous video... great to see the real pumps that use them as you explained their operation. Cheers mate!
Absolutely love your videos! Please make more, you've not had any new ones up in a while, I hope your channel is still going! Great work!
Your great hard work putting this together is highly appreciated. Great presentation
Informative, clear presentation, helpful diagrams. Great video. Thanks!
Adam, need more videos!! You do a fantastic job. Your stuff is unique. Please make more
Great videos Adam. You're exactly what I needed now while I struggle to pass my Refrigeration engineer written exam lol. The video and information is actually priceless
Some of these I've never seen demonstrated, and one I had never even heard of! Great video, thanks.
I really respect the amount of effort put in this video. Great job.
after browsing 100 of videos... this one simple video made me understand the basics. thanks mate... all the best
Very good, clear and direct to the point explanations!!!Thank you
It is really great that you are uploading such videos, it really helped me.
This is information I never knew I needed to have! AWESOME!
Awsome!!! thanks for short and awsome intro to the positive displacement pumps
What an amazing resource, I appreciate your excellent examples. You made it much easier for me to conceptualize the inner pump workings than the textbook I've been staring blankly at. :D
The cutaway/acrylic window for the peristaltic pump was pretty cool. Nice work man.
Excellent discription. Very high clarity of concept and thoughts. My compliments.
Excellent work! A good explanation along with the real time examples... Cheers!
You're killing it bro. Keep it up.

Excellent video - Your explanations and models made it immediately intuitive how each pump type worked. I'd love to see a follow-up talking about some of the pros/cons of each pump type, and some examples of where they're used.
Best instruction ive ever watched. Serious, i wish you taught every topic in trade school
Awesome quality and an amazing job of explaining the different functions.
Great video...well articulate, speech speed perfect, & accurate descriptions. Well Done !
Just discovered your channel. Up there with the best content I have ever seen. Thanks. I did learn something, lots!
Thank you for taking the time to make such an educational video, with physical and animated examples. Highly appreciated

Watching it in 2022 and it's awesome!!! Really helpful the way you choose to explain pumps is amazing! It gives us real knowledge while watching actual pump motions
animation and your explaination at the Same time! Very thankful to you! ❤️
Brilliant video... Thanks for the efforts to put this together
Technology has changed so rapidly it's refreshing to see passionate, concise, explanations.
Fantastic video mate. When I worked in hydraulics most of these type of pumps were used. Some of them were very hard to deal with when it came to maintenance. All of them worked very well and preformed beautifully. Thank you for your time in the production of these well made mini doc's.
Thank you so much for this explanation! I am studying pumps for work and being able to see the movement is much more helpful than looking at illustrations. Your verbal descriptions were also much simpler and more concise than my textbook. ❤
Thank you so much for your video.
I learned a lot by watching the video and am impressed by how professional and polished your presentations are.
Thumps up!

I love your videos! Please make a video about the different types of valves and their applications.
Now I can imagine different motors better.
Thanks, great vlogging.
this video was exceptionally explained! couldnt have asked for a better explanation of terms well done sir!!!!
Thanks man for this video. I got to learn so much about positive displacement pumps.
Simple schematic & explanation + Actual parts = You rock👌🏻
2:50 These can also have variable displacement by tilting the thrust plate. Those little holes are for some of the pumped medium (usually oil or fuel) to act as a hydrodynamic bearing for the pistons.
A typical use case is a hydraulic pump or aircon compressor.
Great basic overview. Simple explained and easy to understand. Ideal for beginners. Superb!
That was a comprehensive presentation. Well done dear 👍👍👍
Awesome channel! I’m currently learning about these exact pumps in school very well explained! Thank you 🙏
Wow, an actual channel for millwrights by millwrights. Never thought I'd stumble upon this.
