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.

Unless all of these were in your back pocket, This was an expensive video. Nice job on the explanations.

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.

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.

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.

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!

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.

Awesome videos Adam! In 4th year millwright and you cleared up a lot of mysteries for me! Thank you! Keep them coming !

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! ❤️

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.

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

Thank you for taking the time to make such an educational video, with physical and animated examples. Highly appreciated

Wondeful. Straight to the point, simple explanations with easy to understand models. No shitty music. Absolutely wonderful, thank you very much.

You're killing it bro. Keep it up.

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.

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!

I really respect the amount of effort put in this video. Great job.

I love your videos! Please make a video about the different types of valves and their applications.

Awsome!!! thanks for short and awsome intro to the positive displacement pumps

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. ❤

Informative, clear presentation, helpful diagrams. Great video. Thanks!

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 ❤️🙌🏾

Thank you so much for sharing this great video with us! It feels way better to get an idea by watching real-life 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

Fabulous video... great to see the real pumps that use them as you explained their operation. Cheers mate!

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.

Adam, need more videos!! You do a fantastic job. Your stuff is unique. Please make more

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!

It is really great that you are uploading such videos, it really helped me.

The cutaway/acrylic window for the peristaltic pump was pretty cool. Nice work man.

Your great hard work putting this together is highly appreciated. Great presentation

Some of these I've never seen demonstrated, and one I had never even heard of! Great video, thanks.

after browsing 100 of videos... this one simple video made me understand the basics. thanks mate... all the best

Wow, an actual channel for millwrights by millwrights. Never thought I'd stumble upon this. Hello from BCIT!

Very good, clear and direct to the point explanations!!!Thank you

Just discovered your channel. Up there with the best content I have ever seen. Thanks. I did learn something, lots!

Great video...well articulate, speech speed perfect, & accurate descriptions. Well Done !

Amazing, thanks a ton. please keep posting more such videos.

Simple schematic & explanation + Actual parts = You rock👌🏻

this video was exceptionally explained! couldnt have asked for a better explanation of terms well done sir!!!!

That was a comprehensive presentation. Well done dear 👍👍👍

Thanks man for this video. I got to learn so much about positive displacement pumps.

Nice to revisit the basics. Some variants in terminology, the progressive cavity pump is also known a worm pump, The internal gear pump is also called the spur and crescent.

awsome video!!!!!. i have completed BE in mechanical, but never seen real life examples.....great video!!!

This is the awesomeness 👌.. explanation of hydraulic pumps. Seeing the real life pumps in action. Number 1 video. Great job.

Now I can imagine different motors better. Thanks, great vlogging.

Brilliant video... Thanks for the efforts to put this together

It's awesome. Thank you for your effort and time you put on making such a great educational video. 👌🙏

it was exceptional explanation sir....... thanks a lot

This is the video what I wanted!! It's very helpful to understand many pumps. Thank you for your hard work😄😄

As a maintenance mechanic in a waste water treatment plant I have been exposed to most of these pumps. Excellent explanation and visual aids in n the production of this video.

Just discovered your channel and it's great. Thanks for all the info!

Finally I understand that last pump. Thanks.

Nice video to understand the basic types of pumps. Briefly illustrated the working principle of each pump by showing the animation. Placing the actual model next to the animation helps to understand how the pump actually looks and operates. Brief application has been explained for Peristaltic pump saying it can used for high viscous fluids. It would be great if similar kind of brief application is provided for other pumps as well. Thanks for such a nice video bro..

Thanks a lot for introducing various type of pumps. it helps me to understanding so much.

Very informative and knowledgeable video . It helped me to understand each type very easily . Thank you so much Sir for your kind information .

This is your daily dose of Recommendation + Displacement pump
