A centrifugal pump has a bit that spins round, (an impellor) inside a case. When the inside of the casing is full of liquid and the bit inside spins round, the fluid is flung outward to the sides, by centrifugal force. An outlet pipe in the case allows the fluid to exit.
If the fluid exits, then something must take it's place, a vacuum is formed. The point where cenrifugal force has least effect, is the dead centre of the bit that spins, the impellor. Arrangement is made in the casing (volute), for fluid to enter at the centre of the impellor and get flung to the sides again.
A cenrifugal pump needs to be full of fluid, before it can act as a pump. They are no good at gasses, like air. They are best placed below a liquid so that they fill naturally. They can be made to work above a liquid, but must first be filled with liquid, before starting. This is known as 'priming'.
What else can I help you with?
Why centrifugal pump cant work on air but centrifugal blower works?
it is due to the difference in the air intake and impeller construction.
What different between centrifugal pumps and multi pumps?
A centrifugal pump works by using centrifugal force. A multi pump is short for a multistage centrifugal pump with two or more impellers.
Is turbine pump is a centrifugal pump?
yes that is centrifugal pump because the turbine pump creates a vacuum pressure on pipe.

What is volute centrifual pump?
The volute of a centrifugal pump is the tank that holds the liquid being pumped. The centrifugal pump is a type of pump that uses a swirling motion to pump liquid.
How centripetal pump works?
Centripetal pumps, also known as centrifugal pumps, work by spinning an impeller that creates a centrifugal force, which moves the fluid towards the outer edges of the pump casing, generating pressure that forces the fluid out through an outlet. This constant rotation and centrifugal force create a continuous flow of fluid through the pump.
Why do you start the centrifugal pump with the discharge valve shut?
centrifugal pump should be fill with liquid to built discharge pressur.chemist.yasser.Naguib
What is the difference between volute centrifugal pump and turbine centrifugal pump?
voloute convord the pressure into volicity and the mixtur of propallere and impeller is called turbine pump
How does water pump work?
The centrifugal pump works in the same way as you use the straw. As the engine starts, the impeller turns which forces the water around it out of the pump's discharge port. ... When the water hits the rotating impeller, energy of the impeller is transferred to the water, forcing the water out (centrifugal force).
Why the centrifugal pump is called high discharge pump?
for a simple reason because it has high discharge than any other available pump. the centrifugal pump uses the centrifugal force to push out the fluid centrifugal force = (mass *velocity2)/radius. hence centrifugal force is directly proportional to the square of the velocity, in this case being the velocity of the fluid. power provided to pump proportional to the force exerted by the impeller.hence higher the power results in higher centrifugal force implying square of the velocity of the fluid. higher the velocity of the fluid higher the discharge of the pump.
Why is a centrifugal pumper equipped with a positive displacement pump in conjunction with the main pump?
Because the centrifugal pump cannot pump air due to its loose tolerances, the positive displacement pump is needed to create the vacuum.
What is difference between monoblock pump and centrifugal pump?
A monoblock pump is a small pump that has no base plates, couplings, or guards, which keeps it small. A centrifugal pump is larger, with added features and impellers to give the pump hydraulic lift.
