In this article I am going to discuss about centrifugal pump. But Firstly, we know about a pump.
What is a pump ?
A Pump is a device or machine used for transferring liquids or gas by the mechanical action.
There are two types of pumps :
1.Dynamic pump
2.Displacement pump
What is the centrifugal pump ?
A centrifugal pumps is a rotodynamic pump. It is designed for transferring liquids or gases. Liquids or Gases transfer from suctions to discharge sides by converting kinetic of energy of liquids into potential energy.
This Pump Come in Rotodynamic. It is Because of Rotations of impeller.
Now, Firstly understand how it works and after that discuss it’s various parts, applications , advantages and Disadvantages
Working Principle of Centrifugal Pump
As we have discussed above this pump works on transfer of rotational or kinetic energy through rotor of blade.
Let us understand in details.
Fluid enters the casing of a centrifugal pump. It falls on the impeller blades at the eye of the impeller.
Impeller rotates with high speed. Liquids on the impeller thrown out and exits the diffuser of the pump.
The fluid gains velocity and pressure as it passes through the impeller.
The basic operating principle of a centrifugal pump is that an external force causes a specific mass of liquid to rotate. This forces throws away the liquids from the central axis of rotation and allowing it to rise to higher levels.
Thus, Centrifugal pump works.
Parts of Centrifugal pump
Let us discuss about parts of this pump.
The parts of the pumps are :-
1.Impeller : – Impeller is rotating part of the pump. It transfers kinetic energy of liquids to the potential energy of liquid or gas.
2.Diffuser :-The area of diffuser increases slowly. It helps in converting kinetic energy of liquids to potential energy.
Here, kinetic energy of liquids transfer to potential energy which help in transfer liquids from suction to discharge.
3.Vanes :- Vanes help in guiding the liquid to move from eye of the pump to diffuser.
4.Shaft sealing :- Sealing is provided which prevents the leakage of liquid being pumped.
5.Eye :-From eye of the impeller liquids come in the pump.
7.Stuffing box :-The above whole parts arrange in the stuffing box.
Applications of Centrifugal pump
Today, this pump is used in every industry,
1.For supplying water in the residential areas because of more flow rate output.
2.In the fire protection system centrifugal p/p is apply. It is because output is more so. fire get extinguish easily.
3.For the disposal of slurry or sewage liquids.
4.Use in Food manufacturing industry.
5.Use in the chemical industry.
6.Oil and gas industry.
7.Use for Irrigation in agriculture industry.
The application of pump is in almost all industries.
Now, we will talk about advantages and
Disadvantages of Centrifugal pump
Advantages of Centrifugal pumps
1.It can be used for transferring dangerous and
hazardous liquid or gases. It is because of no leakage.
2.Very less frictional loss in this pump. Due to no rubbing surface.
3 It is very easy to operate and no need more experience.
4.efficiency of this pump is high.
5.Less noise.
6.Less maintenance.
Disadvantages of Centrifugal pumps
1.The main disadvantages of this pump is rotation. This pump use rotations instead of suction. Due to suction, it cause very less suction power at eye of the impeller.
2.Priming :- Priming of Centrifugal pumps means filling of stuffing box fully with water. So, Before Starting liquids is filled in the pump.
Priming is done so that air inside get removed.
3.Cavitations :- A Cavitation is a process occurs on impeller. When liquid inside the pumps change into vapour at low pressure.

In Conclusion : This Pump is best pump in all pump because of less maintenance and high efficiency. So, it is used in every industry.
