Priming:
- Priming is the process of removing air from the pump and suction line.
- In this process, the pump is been filled with the liquid being pumped, and this liquid forces all the air, gas, or vapour contained in the passageways of the pump to escape out.
- The necessity of priming a centrifugal pump is due to the fact that the pressure generated in a centrifugal pump impeller is directly proportional to the density of the fluid that is in contact with it.
- Hence if an impeller is made to rotate in the presence of air, only a negligible pressure would be produced with the result that no liquid will be lifted up by the pump.
- As such it is essential to properly prime a centrifugal pump before it can be started.
