CENTRIFUGAL PUMP :-
It is dynamic pressure pump.
Fig. Shows the schematical layout of centrifugal pump, It consist of-
1. Strainer.
2. Foot valve.
3. Impeller.
4. Suction pump.
5. Casing.
6. Blade.
7. Delivery pipe.
8. Electric motor shaft.
WORKING:-
Before starting of electric pump the whole pump including casing , delivery pipe, suction pipe are completely filled with water.
This process is known as PRIMING PROCESS.
(for removing air pockets.)
The start of electric motor causes impeller to rotate due to which the vaccum is to be created inside the casing.
Hence, the water from the sump enters into the casing through suction pipe.
The further rotation of impeller causes the water from the casing is deliver to overhead tank at high pressure.
