▶️Introduction
Centrifugal pumps are used in many applications all over the world. The pump is ideal for pumping fluids with a low amount of suspended bodies e.g. water. The centrifugal pump is low maintenance, reliable and relatively cheap.
Operation
Liquid is drawn into the impeller and flows outwards away from the impeller eye due to centrifugal force. The change in cross sectional area of the impeller vanes and volute casing causes the velocity energy to be changed to pressure energy (Bernoulli’s principle).
PHYSICS DISCLAIMER :Centrifugal force is an imaginary force, only centripetal force is a true force, but it is beyond the scope of this video to clarify this concept further.

[@arsalankhantareen2682]

very impressive. specially the part when we were fluid and moved through volute :p.

[@rongarza9488]

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".

[@southpaw8168]

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. 🇮🇳🇮🇳🇮🇳🔥🔥🔥

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.

[@mayankdixit3747]

@saVRee 3D What is the need of converting kinetic energy to pressure Energy? Why can't we discharge it with kinetic energy only?

[@barsgursoy5976]

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.

[@noumanashfaq7419]

Which software you are using which is allowing you to move your cursor inside the model?

[@YassineBoubcheur]

Good explanation ! But what happens if we dont increase pressure but instead we let water flow with high velocity ? Thanks !

[@ian10quan]

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!

Thank you sir your video is really helpful for me nd keep on make new videos I love u

[@jidendrap3745]

[@gloomyend1232]

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?

[@salama_world]

I like the presentation...which software is that?

[@savree-3d]

You can access the model for free at saVRee.com. Check out the 3D models or encyclopedia section.

[@salama_world]

@@savree-3d thankyou

[@PertupDelom]

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.

[@isaacamaranolo2787]

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

[@disrael2101]

doesn't pressure increase should correlate with the speed? as the smaller the hole the speed increase that makes sense but i thought the pressure should increase as well due to the narrower hole and the quicker flow or?

[@barsgursoy5976]

Great point. When he says "pressure" he means static pressure. The one you are talking about is "dynamic pressure". Think about it this way, if you have a baloon filled with some air and enclosed, it has some pressure in it. When you squeeze it, you feel that it resists your squeeze. Total air in the baloon is the same, so compressed that air and increased its static pressure. Now if you open the cap of the baloon, the air will leave it faster than if you have not squeezed it. In short, you first increase the static pressure and then convert it to dynamic pressure ( in other words flow speed). Now, in case of water, since it is not compressible ( in practical terms) when you squeeze by forcing it to accumulate through the outer diameter of the impeller, you directly convert static pressure to dynamic pressure ( velocity)

[@keqixuan2369]

Same as what I am wondering

[@madderubasavaraja5596]

Sir may be suction from impeller eye or vans in slurry pumps pls give me answer any one?

[@christopheroptimusprime2631]

You this pump get it start in archamedees screw

[@joseh7612]

why do we need the pressure to increase in order to move to the next place?

[@Saikiran-qb2yo]

I think the impeller must rotate anticlockwise direction..
