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
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.
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.
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.
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.
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. ❤
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! ❤️
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!
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 ❤️🙌🏾
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.
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!
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.
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
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
i watched this video today and i find its very helpful for Mechanical technicians and supervisor to maitain them and also for interview questions mostly asked by the interviewer💯
7:15 the image in the left (actual hardware) shows the vanes opposite each other are physically connected, thus the retracting vane is pushing the other vane outwards. Centrifugal force is not required (and would not be reliable at low RPM). This only works in a circular housing. Some vane pumps use springs to hold the vanes against the housing.
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..
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.
peristaltic, rotary lobe and diaphragm pump are widely used in pharmaceutical production especially in biotechnology since generate less shearing forces. Peristaltic and diaphragm pumps are used in single use systems for pharmaceutical production - one can easily separate pumping element and pump drive - lower contamination risks
The rotary progressive cavity pump is used as a concrete pump. The housing is made of hard rubber and can withstand sand and small rocks in the pumped mixture.
Thank you again, great video, quick question regarding the cavity pump, what would be a better option then the cavity pump, we are pushing higher solids, is liquor that contains dical, thank you
Don't use slang or your workplace's jargong in questions, there's no substans with the name dical. Do you mean dicalcium phosphate or some similar rather abrasive slurry? In case of heavy wear on progressive cavity pumps, I have sometimes switched to peristaltic pumps (hose pump) instead. They are generally more tolerant to abrasion and work good if the pressure is not more than a few bars and the temperature is below 80 °C. Just be careful with the pulsations. A diaphragm pump can also work if the viscosity is not very high.
Thanks to the vedio you made. I have a question of a pump that is appropriate in small sized, quiet operationing and has a powerful pressure. what type of pump would it be? I would be very thankful to someone expertise's advice.
Awesome video. Got a question: I currently have a GD GAFMDRAX/6mr dual lobe blower in shop for repair. These have the compression collar on each shaft for locking the gears to the shaft. I have done only 3 repairs to blowers previously with ordinary shop and machinist tools. Are there any specialty tools specifically for blowers that would make blower repairs as precise as possible, other than mics, calipers, feeler gauges, etc.?
Hi Adam, quick question, if you had a choice among these pumps, which one would you use as a high pressure pump in case of gasoline ? since lubrication is a huge problem, when considering gasoline.
About the vane pump, is that centrifugal force instead of spring load pushing the vane on the casing? Or just in the video, is the solid shaft connecting 2 opposite vane to the casing?
the vanes are loose and are trapped by the front and back covers. The pump must never run dry though as it relies on the fluid to lubricate the vane face and the outer casing and also the slots the vanes sit in. The vane holder is offset so the vanes are pushed back in as they near the top of the case. Look up JABSCO Vane pump!
What was cause your rotor bolt to snap during operation?.. usually the bottom fro. What I've seen... spacing between rotor bolt and cover was my 1st hunch... but nat too sure anymore as I just removed another broken rotor bolt and the head of it has no scratches like if it were to wedge itself between the cover and theeads.
Ignoring normal use-case restrictions, I wonder what the noise comparison would be like for each style pump if they were designed for the same flow/pressure.
Are any pumps driven by temperature? Imagine the oil in the AK pipeline has to be warmer to make it more viscus for pumping. If the temperature cools and the oil is more difficult to pump, do the pumps shut down until a temperature sensor tells it to pump again?
That was the best. Just what I needed. Thank you. I am making multi story, mobile, off grid, balcony sized, solar powered, aquaponic system s & I'm having a hard time finding he best pumps. I think a mini, vertical, rotary progressive cavity pump would do the trick.
Interestingly, rotary vane pumps are common in roughing vacuum pumps, and piston pumps in compressors. I’m guessing it has to do with the way the two systems work that one can achieve a better vacuum/high pressure.
GRBTutorials, that is exactly the case, take for example a gear pump, eventually the fluid can compress so much that it fits back though the mesh between the gears. And with vacuum, I’m not sure if the reason.
I am working on a pump concept, and want to ask, what material can be used as a diaphragm? main concern durability leather latex 100% silicone or maybe sinew

but you didn't mention the gerotor pump
Hi, EP,
You're right! A gerotor pump is essentially an internal gear pump without the crescent.
Now I can imagine different motors better.
Thanks, great vlogging.
Thanks a lot for introducing various type of pumps. it helps me to understanding so much.

leather
latex

or maybe sinew
Usually standard Rubber as its cheaper. Different rubbers have different elasticity. Check out Wilden pumps
Do all these pumps increse the pressure of the fluid or do they just increase the kinetic energy?
Aman Deep
Pumps create flow. Downstream restrictions create pressure.
