- The Centrifugal pump impellor is connected with an electric induction motor by a shaft, which converts electrical energy into mechanical energy. This mechanical energy is used the drive the pump. The pump increases both kinetic energy and hydrodynamic energy (pressure energy) by converting the mechanical energy. The centrifugal pump transport fluid by converting mechanical energy into kinetic energy and hydrodynamic energy (pressure energy).
- The impeller is the heart of the pump. The impeller has a series of curved vanes fitted inside plates. The impeller is always submerged in water. When the impeller is rotated, it makes the fluid (liquid or gas) surrounding it also rotates. As the fluid rotates, the fluid is radially pushed outward in all directions to the end edge of the impeller vanes by the action of centrifugal force and the fluid is go towards the discharge side. At the discharge side of the impeller, both kinetic energy and pressure energy of water will rise.
- As the fluid (water) moves from the center of the impeller to radially outward, the negative pressure will be induced at the eye of the pump impeller. Such a low pressure helps in sucking fresh water into the pump continuously.
- The water enters from the eye of the impeller, going or trapped between the vanes. As the impeller rotates, it imparts kinetic energy to water and increases the velocity of the water. With this high velocity, the water is strike the wall of the pump casing and water is starting collecting in the volute chamber. As the water collects in the volute chamber, it slows down and the kinetic energy of water starts converting into the pressure energy. The flow of water remains continuous behind this. This maintains the pressure as well as the?flow rate of water in the pump and allows the water to be pushed through the pipes.
