Centrifugal Pumps

[@profrosemberg]

Hi, Adam, I´ve been a teacher for 40 years. I´ve never seen such a flawless class. Congrats!!!!

[@trygveskogsholm5963]

"Pressure Energy" really?

[@lesmurphy8466]

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 KZbin or any other platform. Well done!

[@ChadAbney]

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!

[@merkov8715]

I wish I knew this channel back when I was studying Mechanical Engineering.

Hhhhhhhh me two ،، but It's not too late to learn 😁

[@westvalley411]

LOL...how old are you...didnt you know Al Gore recently invented the internet...so there was probably no KZbin.....just kidding

[@alwyndsilva1858]

Thought so too

[@HubcapPointOutdoors]

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

[@IRELAND_SAYS_NO]

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

[@jason1440]

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.

[@tylerrivas5397]

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

[@timcha69]

I needed this mini-lecture for so long. The BEST explanation of the physics of a centrigufal pump!

[@AmanKumar-wh8tk]

Ah man, you're awesome sir. This is the kind of teacher i want to have in my most regrettable curriculum -Mechanical Engineering.

[@ElZamo92]

Aman Kumar the explanation was a very gross simplification of fluid mechanics. There’s A LOT more to this than what he explained.

[@alvaromelgarejohernandez4313]

@@ElZamo92 think he accomplished a lot in a 8:25 min video lol

[@karthiixk]

But hopefully we won't get any teachers like him in our class😅

[@shmuelbenmoshe2966]

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.

[@stardumpling]

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!

[@hopydaddy]

Excellent video. One of the most clear explanations I've seen... This is what makes KZbin worth watching.

[@Richaleks]

Thank you, man. You are better than my teacher at the university.

[@jimhallmark8680]

You have done a very nice job explaining the basic hydraulic principles in pumping.

[@illfatedgoodheart4951]

One of the best explained videos of centrifugal pumps i have ever seen.

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!

[@Emerson_Beau]

No you ain't 😂

[@Thrill98]

very informative video. you have mentioned every single important aspect of centrifugal pumps and nothing has been missed

[@drjae599]

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.

[@billiondollardan]

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 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

[@alanc.4437]

Marvellous, it's a really good video for refreshing the concept of centrifugal pump ... The explanation is clear and concise. Way to go, Laney

[@tomsterism]

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!

[@charljoubert7908]

great lesson! I've been irritated by pool maintenance a bit in the past but now i have some theory to make it interesting :)

[@patrickhickey4029]

this was honestly a turning point for me understanding the centrifugal pump. you are the man gracias

[@133wavi]

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

[@MaverickSu-35]

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).

[@jpf1950]

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?

[@erikmichon5906]

Holy nuts I've never subbed so fast. Great commentary, scripting, hosting, diagrams, editing.... How am I just finding this channel now?!?

[@photog1529]

Very informative. As a mechanical engineer, this presentation was spot-on.

[@verdatum]

These vids are great. I hope you keep at it! It'd be interesting to see a vid contrasting pumps and blowers.

[@brenthawkins204]

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.

[@gunnyliu4515]

I've never been interested in physical machinery until this. Thanks for the super-clear and super-engaging explanation! Keep it up ;)

[@oncefuture7179]

you've helped me so much over the last 2 years of school. Just wanted to say thank you.

[@almaaburto6990]

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.

[@JuanSanchez-nn1db]

Existen varios videos donde explican el ciclo de refrigeración . Si te interesa te puedo recomendar uno

[@BeyondDuctTapeFixItRight]

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.

[@dirkwellnitz3783]

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

[@klinsmandoku3860]

This video is very educative and it's helping to know and understand more about C.pumps.

[@ivansolares2448]

Im looking to get into the O&G industry. Glad I stumbled across your videos.

[@kawasabi1]

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.

[@davidtiah]

Your'e a live saver Adam! Needed a crash course and you gave me one.

[@marlonmiguel3279]

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.

[@thoapham2081]

Hi, You are a great teacher because it is clear and contain all information in a short video.Great

[@jwccsnm]

Adam, You should do a video on pump curves. Centrifugal and PD curves.

[@davidbrady5890]

great job. A video on pump curves is a great ideaa

[@Kendallian132]

Excellent presentations! My new word of the day: "Cutwater". I never realized there was a term for that part of the volute/casing.

[@civedm]

I learned a lot. Thanks. I remember all this from Physics. Its nice to see someone explain it like this.

[@kaptenrobert]

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 :)

[@elishanyakarombo9340]

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?

[@suzesiviter6083]

Good, many on here are dumbed down, yours gives just the right amount of good information.

[@kennyrawlings6290]

Very classic video. If you want to build a pump, for getting sand of a riverbed, which material is suitable for the impeller?

[@marwasulaiman1765]

[@alazanjoe]

VERY WELL EXPLAINED GOOD TO WATCH FOR NEW AND SEASONED INDUSTRIAL MECHANICS THANK YOU FOR THE VIDEO

[@OtakuSanel]

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.

[@danielgreer3906]

Great job studying for fire department engineers test you did the best

[@hamidhaghnazari2036]

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

[@frostyab7579]

nice, but you are propagating number of misconceptions 1) blades can be backward, forward, or straight, depending on the function of the pump 2) it does not rely on friction to get the fluid moving 3) it can move air and create suction, but it's really bad at it because it is not what it's designed for 4) your Bernoulli principle is grossly oversimplified

[@burtvincent1278]

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?

[@junaidbasha5994]

superb explanation on centrifugal pump

[@thunderloong]

Actually they're centrifugal pumps because they spin the fluid to create centripetal force against the outside shell to cause linear flow into the out pipe. They centrifuge the fluid into a radial motion that centripetally impinges upon the housing and encourages pressure flow in a linear manner out the discharge. The impeller is designed to match the intended fluids, housing volume and flow rate.

[@bartok1378]

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.

[@ddegn]

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.

Great video! Thanks a lot! I wish you also showed and explained about the throttle bush

[@beecrofty]

Super well explained and demonstrated. Great job!

[@MaverickSu-35]

Very nice videos, but I must tell you that it's not the friction between the fluid and the vanes/blades which causes the fluid to move, but the differential pressure between both sides of the blades/vanes which varies with the speed of rotation. The friction force between the fluid and the blades is the result of the fluid's properties (viscosity) and dynamic pressure (relative velocity between the fluid particles and surfaces) and rather opposes the motion of the fluid and in some amount actually reduce the output overall pressure within the fluid, it doesn't help the fluid to move or the pump to do it's job. If you want to confirm it you can simply use two fluids with different viscosity coefs and see how the outlet static pressure reads. The more viscous fluid (thick oil) will have a much less flow speed and static pressure (which takes place at surface contact) but much higher dynamic pressure compared to a lower viscosity fluid (water) which does the opposite, while both producing the same total outlet pressure. It's only the pressures that govern motions. The friction is... friction!

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.
