For a centrifugal pump to function properly, it must be primed. Priming refers to the process of removing air from the pump and filling it with liquid before operation. This is crucial because centrifugal pumps rely on the continuous flow of liquid to create the necessary suction to draw fluid into the impeller. If there is air in the pump, it will not generate adequate pressure or flow, which can lead to cavitation and damage. While having the pump filled with liquid could seem similar to being primed, simply being filled does not ensure that the air is expelled from the system or that the pump can create the suction needed for efficient operation. Lubrication is essential for moving parts in mechanical systems but does not address the operational requirements for fluid transport. Connection to power is necessary for the pump to operate, yet without proper priming, the pump still cannot function effectively. Thus, priming is the critical action required for proper pump performance.
