As someone who has serviced and sold pumps for over a decade, I can safely say that not only did you get all the science and physics of pump design correct, it's also the most informative centrifugal pump video I've ever seen on RUclips or any other platform. Well done!
This video is the best introduction to centrifugal pumps I have found. I teach process technology and direct all my students to this video for their introduction to centrifugal pumps. Well done!
Well done. I learned how to operate these type of pumps that are used in firefighting apparatus many years ago. This is the best presentation of centrifugal pumps I ever seen.
I'm not even studying mechanical engineering... I've just found myself building a pump from scratch... Realized an axial pump isn't what was most suitable, and a centrifugal pump is... designing 3d printing jet drives designed to be used on a kayak is fun... Untill you need specifics on how a centrifugal pump is actually designed and why
Been a plumber for a few years and never really got into the specifications of pumps . Just installed them on jobs which the pump would have been supplied by our engineer and didn't put much thought into them. Swapping to go work for a pump company next week so getting to know pumps and the internals will be a benefit to me now . Thanks for the video
Thank you for the great video. I have a question about the effect of temperature on the characteristics curve of the pump. How does the characteris curve of a centrifugal pump change with the decrease in temperature provided that the pump power is constant. A reference material to read would of great help. Thank you
I work as a shipping receiving manager for a large pump distributor, I'm hoping to move into the mechanical side of our business and this definitely gives me a better idea of how they work please keep making content
I just found this channel almost at the end of 2019. I see that the last upload was like 9 or 10 months ago. I still subbed and hit the bell in the hopes that I'll be able to consume more of your content. It's very well done and I enjoy it
i'm late to discover this but this is amazing. not only is the language easy to comprehend, the animations help a great deal in helping to visualise what textbooks try to convey. thank you so much!
Great video on centrifugal pumps. Anyone in the fire service would benefit watching your presentation, since the most common pump used in the fire service is the centrifugal pump.
I love this. You make the video extremely engaging with the animations. I feel like I learnt something at the end of it, unlike what my engineering college teacher taught me in my bachelors
I work on a ship, a marine engineer. These kinds of pump are very common on our system, we use it for sw systems.. This video is very very helpful for us! Thanks man!
Your work here is simply superb. Very clear, straightforward and accessible to anyone with sufficient IQ. Well done. I think you should have at minimum, a million subscribers!
Speaking of the flow direction based on the centrifugal pump's blades curvature, yes, you should tell in which direction the pump will have it's best efficiency for moving your fluid, hence from the eye center towards the blades tips, but it doesn't mean it won't reverse the flow if you rotate the rotor in opposite direction, but cavitation may occur much sooner (at some lower rpm and outlet pressures).
This was an amazing video. I spent many hours reading through a half-dozen websites trying to understand centrifugal pumps and volutes. You made it crystal clear. Excellent video editing too. Would you also tackle vortexes too?
Dear sir i have an doubt about vertical multistage pumps. My question is Why the vertical multistage pumps are dont have balancing drum arrangement for axial movement due to differential pressure. Then how the pressure is balanced without balance drum. And instead balancing drum system which methods are used to arrest the axial float in the vertical multistage pumps.
Great clear video and learned a lot from it. What type of residential pump and what capacity would you recommend to fill a water tank placed on the roof deck of a 7-story building with height of around 25 meters or 82 feet. Currently we are using a 1.5 horse power jet pump on a 1-1/2" diameter vertical pipe. The plastic impeller breaks every 6 months! Any suggestion please. Thanks.
magnífica explicación Adam!! muchas gracias!! :) ojalá sigas haciendo muchos más para quienes estudiamos una carrera técnica o ingeniería. Could you explain how an air conditioning works? I can´t already understand how it changes hot air into cold. Saludos desde Veracruz, México.
Pretty good thank you. Are their any formulas that would apply concerning impeller diameters, thickness and speeds that could be used to determine horsepower from resultant flow and pressure?
Excellent video. I pump water for irrigation using a diesel engine connected to a pump. The diesel engine has a fault. What happens when I pump water from a gasoline water pump and let it go through the main pump (the one connected to the non-working diesel engine). Would this reduce the pressure of water reaching crops on the other side?
Adam, your video was an enjoyable watch. The videography is clear and your presentation, content, timing and projection make for an easy to follow experience.
Thanks for the video . Let me ask you a question. Why do aquarium pump and washer drain pump impellers have straight and not curved impeller blades? Aren't curved shaped blades more efficient?
Perhaps, but the efficiency obtained in the impeller format allowed to reduce the power required for the same result. qph.fs.quoracdn.net/main-qimg-03033dbb01739d2f400157af07be8d38 And as they are all made of injected plastic, the machining cost only occurs in the mold. Even the number of blades that is usually only 4 is inefficient. Some even low power pumps get better results with curved blades like this ae01.alicdn.com/kf/HTB1UI_qU3DqK1RjSZSyq6yxEVXav.jpg
thanks for video.if low pressure or restriction causes Cavitation in the pump . why it doesn't happen in A/C system when it goes from high pressure to low pressure(orifice tub or TXV).
Pumps 101. Awesome. I understand that changing the impeller by just a little controls volume and preassure immensely. Most trash pumps do high volumes with low pressures. Fire pumps do higher pressures with lower volumes. Dredge pumps for small gold dredges are somewhere in the middle. Pump design is tailored specifically for its specific use and hose size.
My years in the Navy we worked on these pumps all over the ship. Firemain, Chill Water, List Control, even air ventilation where a non sparking unit was needed or for high air pressure like the Buffalo Forge Centrifugal fans.
Great video. I just don't understand what you mean when you say that these pumps can't be used to move air. They use centrifugal compressors all the time in aviation to compress the inlet air. Was hoping you would clarify what you mean here.
Great video and explanation! You deserve more views which you should get as your content is better known. I loved your command of English language too! Cheers!
Do you want to increase the preasure to get the fluid where you want it beacause at a lower preasure there might not be enought preasure to move the fluid to where you want it or?? Sorry I'm new to this.
hi . thanks for this video . I have two questions... 1- whats the effect of water solid content on impeller pump, 2- whats mean by solid content , is sand in water one of the this solid?
Would a frictionless impeller work? I think it would likely work better than an impeller with high friction. I think your explanation at 1:48 is incorrect. Friction isn't required to push the liquid. I think friction actually makes a centrifugal pump less effective. This is a small nit pick. I've been enjoying your videos. Thanks for sharing them with us.
Do you know what is likely cause of a pump motor flipping breaker breaker for after 20 seconds? 3 phase 3 HP, hot cooking oil, capacity 6 cubic meter/hour discharge, 25m head? Pump spins freely apart from motor...thanks
I have to have a 150ft long 1inch inside diameter pipe in front of my gas water pump because can not have the pump at the ditch where there is water. The property of my neighbor is about 150ft deep and he might allow me to run a pvc line but I am worried that the intake line would be way too long and too much air in it and would damage the pump.
I thought vanes decelerate liquid increasing pressure. also how does it create suction. I'm kind of confused on that. once it's primed, what creates the vacuum to keep sucking.
Hi Adam. Thanks for the awesome video. Got a question about centrifugal pump. Should the discharge pressure and suction pressure be equal? Or there should there be DP? Thanks!
Hi, Derrick, During operation, there will definitely be a pressure differential between the suction and discharge sides of the pump. The amount of pressure on the suction side (before energy has been added to the fluid) will be less than the amount of pressure on the dicharge side (after energy is added to the fluid). The actual amount of discharge pressure is determined by the amount of energy added to the fluid by the impeller (based on impeller speed, impeller diameter and the density of the fluid) and how much of this energy is in the form of pressure. The pressure developed by the pump is actually dictated by the needs of the piping system. Bigger elevation changes from the source reservoir to the destination reservoir and greater lengths of pipe between them demand more pressure from the pump to overcome these obstacles. As for suction pressure, during operation, fluid is discharged from the pump and this creates a zone of low pressure at the center of the impeller. Fluid in the suction piping is pushed into the pump to replace the discharged fluid. This is accomplished through a combination of atmospheric pressure and the weight of any fluid above the pump on the suction side - ie the fluid level of the source reservoir. This is what determines the actual amount of suction pressure. We haven't yet made a video on pumping system hydraulics, but you can be sure that such a video is on the list. The explanation in that video will surely be better and more thorough!
I studied cavitation for nearly a year; man dat stuff if the expansion of the Universe for layman! Surprised/not surprised you didn’t bring it up. 👍🏻😂🇦🇺🤜🏼🤛🏼🍀
Dear this is pretty amazing but still I have doubt, how PE+KE+PrE= constant. How this KE is changes into PrE, as we know that that shape is increasing continuously....?
nice one adam i'am a pipe fitter and mechanical fitter thank's for additional knowledge, nice explanation bro. keep up the good work more vids. to come ☝️💪
Great videos please make a video for what to look for when buying used commercial centrifugal pumps things like (reliable brands , how to check a pump is in a good condition , website for buying /selling used pumps , etc) thanks in advance
Hi Adam! My name is Fernando and I'm from Brazil. I like your classes and I've a doubt. Can you help me, please? Do you have a blue prints that shows the centrifugal pumps components? I mean...I'd like to learn about the English names for the whole pump.
Thats a very good explanation, but there is one remark I cannot hold back. A centrifugal pump does not create pressure! It creates head and flow. Pressure results from friction and resistance within the discharge piping. Assuming an open discharge nozzle, the pump would not create pressure at all since the fluid would be exposed to ambient pressure (and negligible friction of air). The pump would shoot out a fountain to a specific height thats called head. Anyhow, you should do more of these videos! thumbs up
Why do squirrel cage blowers have the vanes in the opposite direction of the centrifugal pump when they seem to operate under the same principle? They even have volute chamber.
The videos on the pump are really awesome. Thank you so much, sir. Looking for a submersible pump but didn't find it. Can we get a video about submersible pump?
Can u please explain how velocity energy is converted into pressure energy in volute , I want answer in theoritical way ( don't explain by mathematical expressions )
Wait, how does that increase pressure? I'm sure it did but I'm lost here. So as the V decreases, A also increases proportionally, wouldn't that mean the pressure would remain constant? as P=AV and A1V1 = A2V2 ?
one thing about fluid dynamics that most people don't understand is that while the general rule is that velocity and pressure are inversely proportional, there is a "power" part to it. just like with torque and speed, volts and amp, there is a power limit which is the two combined at any given moment. ie. you can have one pump that does 10cfm at 10psi and another pump 10cfm at 1psi. yea you can get the 10cfm @ 1psi to be at 10psi but it'll only be at 1cfm then. Point being is that while yea that is true, it's not as simple as that and you run into limits very quickly.
Hi, Adam, I´ve been a teacher for 40 years. I´ve never seen such a flawless class. Congrats!!!!
"Pressure Energy" really?

Same
Hhhhhhhh me two ،، but It's not too late to learn 😁
LOL...how old are you...didnt you know Al Gore recently invented the internet...so there was probably no RUclips.....just kidding
Thought so too
I'm not even studying mechanical engineering... I've just found myself building a pump from scratch...

Been a plumber for a few years and never really got into the specifications of pumps .
Just installed them on jobs which the pump would have been supplied by our engineer and didn't put much thought into them.
Swapping to go work for a pump company next week so getting to know pumps and the internals will be a benefit to me now .
Thanks for the video
Ah man, you're awesome sir. This is the kind of teacher i want to have in my most regrettable curriculum -Mechanical Engineering.
Aman Kumar the explanation was a very gross simplification of fluid mechanics. There’s A LOT more to this than what he explained.
@@ElZamo92 think he accomplished a lot in a 8:25 min video lol
But hopefully we won't get any teachers like him in our class😅
I needed this mini-lecture for so long. The BEST explanation of the physics of a centrigufal pump!
Excellent video. One of the most clear explanations I've seen... This is what makes RUclips worth watching.
Thank you for the great video. I have a question about the effect of temperature on the characteristics curve of the pump.
How does the characteris curve of a centrifugal pump change with the decrease in temperature provided that the pump power is constant.
A reference material to read would of great help.

very informative video. you have mentioned every single important aspect of centrifugal pumps and nothing has been missed
Working with these on a daily basis now, thanks for sharing. Helps me understand just a little bit more why the pump won't grab the oil sometimes.
One of the best explained videos of centrifugal pumps i have ever seen.

Such superb animation coupled with clear easy to understand explanation, great job Adam.
VERY WELL EXPLAINED
GOOD TO WATCH FOR NEW AND SEASONED INDUSTRIAL MECHANICS
THANK YOU FOR THE VIDEO
Shame you get so few views. Very helpful, learned a lot! Will recommend to friends.
2 years later => half a million views.
I think there is no shame anymore :)
I thought the rotation of a pump was always CW/CCW as viewed from the bearing frame and not the front of the pump, so would this then be clockwise?
Im looking to get into the O&G industry. Glad I stumbled across your videos.
great video, how I can avoid cavitation in a centrifugal pump that generates a vacuum ?
Good, many on here are dumbed down, yours gives just the right amount of good information.
The quality of education of your video is very good I wonder how it's free.
These vids are great. I hope you keep at it! It'd be interesting to see a vid contrasting pumps and blowers.
he's using subversive nazi propaganda techniques that will program your subconscious mind: 3:35
Do you have some stuff about pumps with stirling engine?
Thanks for the video
.
Let me ask you a question. Why do aquarium pump and washer drain pump impellers have straight and not curved impeller blades? Aren't curved shaped blades more efficient?
A straight line impeller requires less machining and is easier therefore cheaper to produce!
Perhaps, but the efficiency obtained in the impeller format allowed to reduce the power required for the same result.
qph.fs.quoracdn.net/main-qimg-03033dbb01739d2f400157af07be8d38

Adam, You should do a video on pump curves. Centrifugal and PD curves.
great job. A video on pump curves is a great ideaa

OMG!!! you are the best!!! Loved the way you showed everything. God bless you! And shame on 124 dislikers.
Wooow hat off for you man. The way you explained this is so easy and so detailed. I have a project on Centrifugal pumps and am certain about a 100%
So the copper must be at an angle so when it’s skived it’s not varying height? If it was flat would the skiving make the thin copper diagonal?
Excellent presentations! My new word of the day: "Cutwater". I never realized there was a term for that part of the volute/casing.
My years in the Navy we worked on these pumps all over the ship. Firemain, Chill Water, List Control, even air ventilation where a non sparking unit was needed or for high air pressure like the Buffalo Forge Centrifugal fans.
the vanes can be curved either way. 3:42 anticlockwise for high flow, clockwise for high head pressure
Thx

This is a small nit pick. I've been enjoying your videos. Thanks for sharing them with us.
I learned a lot. Thanks. I remember all this from Physics. Its nice to see someone explain it like this.
So the volute chamber is basically a diffuser inside the centrifugal pump?
is the viscosity of the fluid play a role on the fluid hydrodynamics?
Please continue making the videos. You ate awesome, the way you explain is the best and your video edits are too good.
Do you know what is likely cause of a pump motor flipping breaker breaker for after 20 seconds? 3 phase 3 HP, hot cooking oil, capacity 6 cubic meter/hour discharge, 25m head? Pump spins freely apart from motor...thanks
Would a worn out wear ring cause loud noise inside the volute? I replaced everything except the wear ring and still making noise
I have to have a 150ft long 1inch inside diameter pipe in front of my gas water pump because can not have the pump at the ditch where there is water. The property of my neighbor is about 150ft deep and he might allow me to run a pvc line but I am worried that the intake line would be way too long and too much air in it and would damage the pump.

College is a scam.
Hmm the pumps i repair always have a larger suction and smaller discharge to build up pressure, why is that?
Good learning from your video. I am going to watch more of your videos for better understanding and learning. Keep posting Adam!
