Introduction to Centrifugal Pump
A centrifugal pump is a mechanical device designed to move fluids by converting rotational kinetic energy into hydrodynamic energy of the fluid flow. It operates on the principle of centrifugal force, where an impeller rotates within a casing, creating a low - pressure area at the impeller's eye. This low - pressure area allows the fluid to enter the pump, and as the impeller spins, it forces the fluid to move radially outward, increasing its velocity and pressure. Centrifugal pumps are widely used in various industries such as water supply, wastewater treatment, chemical processing, oil and gas, and power generation due to their simplicity, reliability, and relatively low cost compared to other types of pumps.
