Priming- If you want to start a centrifugal pump by switching it on, it will not start delivering water promptly. It is due to the fact initially inside the casing of pump air is filled. When we start the pump then lnitially the impeller starts spinning the air inside the casing which cannot develop sufficient centrifugal force to pull the water and deliver it. To make the water to flow, first of all we have to fill the casing with water and then start the pump.In such case the sufficient centrifugal force will be developed and the pump will start delivering water. Further the action of water flow will remain continued because water is entering the pump continuesly (casing is always filled with water not air) so no problem of 'insufficient centrifugal force' arises once the pump starts delivering water. The action of initially filling of casing with water is called as Priming. You can learn the physical significance of priming in centrifugal pumps by this easy to understand lecture.

Thanks mate. I was watching this while priming my well centrifugal pump.. Just to clear my mind..

[@nikhilmewada5681]

Simple and sweet explanation. I love it

[@vijaybgood]

Super sir.. What I was looking to understand exactly..

[@aishwaryamulampaka2644]

Thank you so much sir, this cleared my long-time doubt about priming!! Thankyou

[@SyamirNasrudd]

Thank you sir for the clear explanation, easy to understand and easy to eloborate to others if needed to share the information. Thank you again.

[@KenLohwh]

Thank you for the tutorial. Your explanation allows many aquarium canister filter owners to know the reason why they need to prime their canister filters.

[@Whyknot80]

I finally fully understand. Thank you

[@CarlsonJulius]

my ear is tingling hearing your voice

[@akashgohel5375]

What an explanation sir hats off.....

[@lorcan.oconnell]

Fantastic explanation! Thank you Amit.

[@engrgreat8282]

Exceptional!! This is the best explanation that I have ever seen on priming. Thanks

[@CMZneu]

Great explanation, question i can't get the priming screw open on a centrifugal pump, but the pump if below water level and when i open a return valve that's right next to the pump discharge water starts coming out, because it's below the water level, if this happens does this mean that the pump is primed right? i mean it's full of water so it should be correct?

[@akbarbasha9377]

Thank you sir, very clear explanation, but continue doing videos sir.

[@michaeleke3913]

Thank you so
much for the explanation

[@UmarFarooq-wq9kj]

Very good mentor he is.

[@mpniko]

Best explanation about priming on youtube

[@syedsalikali2428]

Very beautifully explained

[@DaddyKitesTV]

I recently bought a centrifugal pump but it has no priming port. Just the inlet and outlet port. Where do I prime it? Thanks!

[@Dr.AmitMandal]

It could be self priming....

[@DaddyKitesTV]

@@Dr.AmitMandal ty Amit

[@rushikeshfargade6984]

Nice clarification sir
(With example )
Thanks sir

[@marktunstall4577]

Hello, thank you for your explanation. Does the diameter of the suction pipe need to be bigger than the delivery pipe?

[@Dr.AmitMandal]

Yes it does

[@anaswarelayadath]

Very clear. Thankyou

[@joelvideosedward3789]

Thank you so much

[@kapil21911]

Pretty nice explanation

[@affanahmedkhan7362]

jazakallah khair Sir

[@hraynaud]

Great job. Excellently explained

[@impactfact2535]

Clear explanation thank you sir

[@safdarhussain9554]

please told me, when when single stage jet pump lifting start the water letter a few minutes loss the pressure and pump is not lifting the water.

[@Bpr99]

At what level minimum water should be fill for priming( inside the casing) or it is necessary to pump casing should be fully filled with water?

[@superprabal]

Thank you so much. Wonderful explanation.

[@RitikYadav-vl4dd]

thnak u sir ji 4 explaining priming.

[@shyamalim3797]

Kudos to the way of explanation, good job man

[@fatumeshariff7447]

Thanks Man
I appreciate

[@sarveshkalpande6209]

Thank you so much for detailed explanation 👍❤️

[@bishalpoudel3859]

good video thank you

[@osamahaider5267]

Very well explained ...

[@afeefpk]

Technical way of explanation...

[@OZTutoh]

Great video! Thank you.

[@amarapalichatewagh2116]

Very nice video ..it's much helpful for me understanding about priming

[@wad95]

Splendid explanation

[@amolaegade5428]

Dear sir kindly clarify my one doubt because I think there is a slight mistake in the diagram that you have showed at 1:54 I think even the suction line should also be shown completely filled with water in the middle diagram or else the pump won't work...what do you think...please reply

[@Dr.AmitMandal]

This is an indicative explaination for, , 'technically why priming is required ,' it depends on the diameter of suction pipe, if it is sufficiently less no need to fill it with water. strictly speaking there are few more things required, there must be a non return valve at the sump-end of suction pipe. The length of suction pipe must be less than 10 m, Check out my lecture on NPSH.

[@hamayunakhtar8065]

U are awsome sir

[@aditya.dhankhar]

Great explanation. Thanks!

[@BhushanKumar-qy2gf]

Thankyou

[@akashdeep5088]

Awesome explanation 👏👏👏

[@GaneshHosur97]

What happens in the self priming pumps? I mean how does it prime itself?

[@Dr.AmitMandal]

+Ganesh Hosur google it its a big story...

[@soumikchatterjee9223]

Then why are you making video?

[@mpniko]

Self priming pump consist of non returning valve in entry pipe which stop water to going back to reservoir when pump is switched off hence casing remains always filled from the water.

[@vaishnavinemishte1287]

Excellent video 👍👍

Excellent explaination thanks a lot sir

[@deep7924]

Sir pulling force is directly analogous to the pushing force means??thora feel nahi ho raha h kuki same amount or space ko hi to hm vaccant kar rahe h rotation se

[@Dr.AmitMandal]

Elaborate your question

[@Pradeepgk17]

Thank u sir good explanation😊

[@ahmedimtiazrais7209]

thanks for your lecture.

[@CommonIndianyoutuber]

Sir what will happen if we fill the pump through delivery pipe

[@maclinemontero3191]

Thank you sir

[@eleleugochukwu6805]

You explained it better

[@DestroyerWolfFenrir]

Superb

[@thesailor4420]

We need to fill full pipe down to the bottom

[@Dr.AmitMandal]

Technically yes

[@isaacamaranolo2787]

Please sir do I need to change any thing in centrifugal pump to use it as turbine generator

[@Dr.AmitMandal]

francis turbine is reverse cetrifugal pump

[@MohanRaj-fs1bx]

Hi! My pump is 200meter away from where i receive water. So I have to go prime the pump every time when I start the motor. And this happens 2-3 times per day. Is there any way the pump can hold water without priming the pump?

[@Dr.AmitMandal]

Try self priming pump

[@tejaswiniteju91]

well explained..very useful

why motor in our houses are placed at low level. Is reason above what u explained?

[@Dr.AmitMandal]

No that is entirely different story

[@solomonreggae5952]

Dear Sir , thanks for the video.....our lecturer has given us a task on this topic....and this is what he ask...try to google search but not able to find it...the question goes.....
What is the “fundamental equation of centrifugal pumps”? What does each term in the equation mean to the working of a centrifugal pump?

[@hbfanclubrajasthan9740]

Good sir ji

[@bhushanmahajan9099]

Nice

[@PrashantKumar-or8bf]

Great sir

[@engvdo5297]

Sir vacuum is created but what is the logic. I mean it's ok vacuum is creat at center but why center and how ?

[@mandlikprajwal466]

Good

[@AmanChaudhary-ye5rj]

nice explanation sir👌👌

[@aownal-lawati9599]

How can the air effects or damage the impeller?

[@Dr.AmitMandal]

+Aown Lawati it depends upon blade material

[@pranavjadhav1987]

U tell why priming necessary but how it works🤔

[@mdazizulislam9993]

what will happen if i start pump without priming

[@vaibhavgote937]

Adequate force or head will not develope due to air thatswhy delivery of water will not be possible

[@yashasvimishra4905]

Amazing

[@Bodynation7]

this is what i'm looking for

[@unexpectedshadow118]

sir.
plz make a video about Air Starting system of engine

[@aadi-theblogger4425]

Water sucks water, in local language we say put water in pipe water will come . :)

[@anumulapriyanka3270]

👌👌

[@046ahamedahzanm.a7]

so non priming????
