After watching countless videos on centrifugal pumps, I can comfortably say that this is the most well explained on the subject. I am Process Technician trainee and I find this very helpful. Thanks man.
@@kirtan061 I think suction is carried out because of Negative force. The impeller rotates, forcing the air to flow out from the casing. This creates a vacuum in the volute casing which draws the water to flow inside.
Very good explanation. Coming from this business side of plant processing, this is exactly the kind of information I need to better understand the engineering team.
I’m studying for my nyc steam license . Goal I’ve have for 20 years and I’m studying and I find your videos SUPER USEFULL IN MY STUDY.. And I’m sure there’s many others like me . Also great for some of the older timers lol to freshen up on the trade lol currently a nyc plant tender finally got all the high pressure steam time I needed to qualify to take this test I’ve been dreaming about for years thanks for the help .

John outstanding explanation + drawing. I rarely comment on social media. You just won my heart. Felt like i never heard anything detailed like this🙏👌🏻🙌🏻
Negative pressure or suction pressure is created at impeller eye by high velocity of impeller as we know when velocity increases pressure drops and vice versa after suction of water it is imparted high velocity by impeller and by increasing are of volute casing kinetic energy of water is converted to pressure energy hence water is delivered. Thank you so much for such wonderful clear presentation of working of centrifugal pumps. I wish you made such video for reciprocating pump too. Love from India. 🇮🇳🇮🇳🇮🇳🔥🔥🔥

Great presentation! BTW, if the impeller blades were bent backwards and their spin in the volute casing remained the same, the fluid would still be pushed out, with an even higher pressure. The fluid would not get sucked in from the volute casing. I missed this question on an IQ test. Now I think of it as "everything spins away from the center, regardless of blade curvature".
Excellent explanation. please make a video on priming methods of centrifugal pump. Especially central priming unit and self priming centrifugal pump which has a vacuum pump attached to it used in marine applications ... great work !!
Sir, if the centrifugal force, acting on liquid particles, is the only motive force for pumping, there would not exist a centripetal pump there. There is centrifugal, static and dynamic head, which add to the total head created by a pump. At 9:34 - the comment about increasing pressure in azimuthal direction of volute is misleading. Volute is collector, which ideally works with constant pressure distribution (at a particular flow rate) around whole impeller outlet. The increasing area of volute in azimuthal direction is due to increasing inflow (outflow from impeller) in the azimuthal direction. There is azimuthal velocity component decrease, due to constant azimuthal momentum in volute if its radius is increasing. The diffusing part of volute casing is usually placed downstream the throat of the volute. The effective flow cross section is perpendicular to streamlines. It is not correct to compare cross sections by comparing corresponding projection lines between two neighboring leading and training edges of impeller interblade channel, as it is not perpendicular to the stream lines. The activity for public awareness of a pump working principle is appreciable, though. Thank you.
Umm just a doubt If in a straight pipe on increasing area velocity decrease and pressure increases along length then after a certain length the pressure at the end of pipe will be higher ,so won't liquid start flowing backwards?
There is no thing such as pressure energy. There is potential (Static Pressure) and kinetic energy (Dynamic Pressure) . The one he is talking about is converting potential energy to kinetic energy.
Excellent explanation. Doesn't the volute increase in csa because more fluid is entering it from the impeller vanes? A lecturer I had once called a pump simply, a wheel on a stick.
Great video! However, I have a doubt, is there any explanation for the orientation of the impeller blades? I would have thought of an opposite orientation so the blades push the water in the same direction of rotation. Or does it work not by pushing the water but by suction? And then, comparing it with a francis turbine, does both of them have the same orientation or it changes and why? Thank you!
Got confuse Sir,,,,because Pressure is inversely proportional to Area. P=F/A you said as the Area increases the pressure also increases...I think this is wrong....
If you are going to look from F/A perspective, then F is also different in that case, because in the section with bigger Area you should also consider the change in the Force = Mass * Acceleration and we know that the Mass will be higher in the zone of bigger Area. Bernoulli's principle is more based on the mass conservation principle, so when you have the static flow rate in the pipe the Mass * Speed for different cross-sections should be constant. It means, that in bigger areas the velocity will be low and vice versa. Knowing that the energy is also conserved the Bernoulli's equation should be satisfied

Wow, thanks!
@@savree-3d how suction is happening on the first place
pls can u explain

@@MuhammadRahatLatifTousif but isn't that air is not allowed to be in the pump? I'm still confused about this negative pressure
You are a blessing to the learning community, You should be given special contributors award by youtube
I haven't seen such a simplistic explanation other than this video. Thank you teacher for your lecture. ❤
You are welcome!
your explanation is perfect. I watched some other videos, I haven't understood working principle well. thx.
I have spent much more hours to know the exact concept but this 12 mins video made my day .I really appreciate your work ❣️
Glad it was helpful!
Sir in impeller suction creating may be from impeller eye or vans? Pls answer me any persons

THIS IS THE BEST VIDEO LESSONS EVER!!! VERY DETAILED, THANK YOU!!
excellent work !! surfed the whole internet, didn't find a better explanation than this
The Bernoulli Principle is the most counter intuitive law I have ever come across in all of Physics or Engineering.
Your videos are incredible. So much knowledge and learning available explained in a way people can understand. Please keep it up!
It doesn't get any better. Thanks a lot...especially the part where you took us along the fluid flow path into the model. Thanks again.
Best video I've ever came across describing the centrifugal pump , much thanks !
I have seen many videos but this one is the best
Reply
Literally the best one in the whole youtube
I would not have guessed that the pressure decreases when a fluid goes through a constricted area. Interesting. Great video.
Appreciate your sharing. As a new from pumps provider, many thanks for your videos.
wow, these diagrams make my college presentations look like their from the cave man era.
Yeah, we hear that a lot :)
Nice presentation! It brought back memories from physics.
Awesome and an excellent explanation and a very understandable animation.

Thanks for the love! Greetings from Scotland!
i have a confusion, by increasing area pressure increase and speed decrease is that area is of volute casing or impeller blades area???
@@zubairalvi3678 it's the area of volute casing.
I am starting to love these videos.
Thanks. Much appreciated. Put a lot of work into them.
Yes, I believe that.
Amazing explaination !! It would be really great if you do videos on Gear Pump & Lobe Pump. Thanks !
I appreciate you going into the volute casing to show the increase in the cross sectional area.
Too good to be true ❤

Amazing videos😍😍
Beautiful. بہت اعلی
Thanks a lot brilliant exploration 💪 waiting for new vids
from 5:00 to 8:40, what software is used to explain Bernoulli's principle? Is the software free to download? Thank you very much!
let me know too the software used, quite interesting yeh!
@@ayushtailor9941 please let me know as well, it would be very helpful, thank you.
Great video ❤
Thank you sir.
Very good video
Superb superb 👌👌👌
Thank you
thanks so much for informative contents
Awsome videos
Great video
Very clear and precise explanation. Can you also do a similar one for vacuum pumps? Thank you!
Will put it on the list.
thanks
Nice video
very impressive. specially the part when we were fluid and moved through volute :p.
Congratulations !
Nice animation
What a great explanation !!
Thanks mate
Thanks so much for the video
So what's the advantage of increased pressure over velocity wen discharging the fluid
நன்றி
nice
nice annimated video
well made video. Have my like, good sir.
Good explanation !
But what happens if we dont increase pressure but instead we let water flow with high velocity ?
Thanks !
Thank U ☺️
Welcome 😊
Thank you so much
You're most welcome
Wow!! .. amazing explanation
It was perfect. Thank you.
Wel done...
Umm just a doubt
If in a straight pipe on increasing area velocity decrease and pressure increases along length then after a certain length the pressure at the end of pipe will be higher ,so won't liquid start flowing backwards?
@saVRee 3D
What is the need of converting kinetic energy to pressure Energy? Why can't we discharge it with kinetic energy only?
There is no thing such as pressure energy. There is potential (Static Pressure) and kinetic energy (Dynamic Pressure) . The one he is talking about is converting potential energy to kinetic energy.
Would like to see a video of a newer or modern SAG MILL drive . They are so well enclosed that it’s hard to visualize the gear arrangements ?
Very nice

tanks
Well explained ..... Can I ask you that which cad software is used for model and for explaining pressure and velocity relation
Thank you!
Nailed it.
nice job
what draws the water into the eye originally????, for instance, at 3:53 the 'liquid would flow into the eye.....', sure but WHY?????
Which software you are using which is allowing you to move your cursor inside the model?
It's kind of counter-intuitive, seems like water moving at higher velocity would exert greater pressure - not less. Thanks.
thank u sir

You can access the model for free at saVRee.com. Check out the 3D models or encyclopedia section.
@@savree-3d thankyou
Hi mate, may you share the name of the software being used in the video?
Grate explanation
Sir may be suction from impeller eye or vans in slurry pumps pls give me answer any one?
Would you tell, which software you used, especially during explanation of Bernoulli's Theorem?
thanks to your parents for making u exist in this universeeeeeeeeeeeeeeeeeeeee
