A centrifugal pump operates on a simple principle: converting rotational energy from a motor into energy that moves water. The pump's impeller rotates, creating a centrifugal force that pushes water from the center of the pump outward into the discharge pipe. This action allows the pump to generate flow and pressure, making it ideal for applications where continuous water supply is critical. Centrifugal pumps are preferred in domestic water systems for several reasons: they provide smooth and reliable water flow, can handle varying flow demands efficiently, and are easier to maintain compared to other pump types. Their compact design also makes them suitable for installation in tight spaces, a common requirement for residential settings.
