RAFSUN smart water pump being inspected by a professional engineer in a residential outdoor water system, showing how a pump loses its prime when air enters the suction line and interrupts water flow. The image features a realistic stainless steel household booster pump connected to blue and white PVC pipes with a brass valve, while the technician checks the unit without showing his face. This scene illustrates a pump running without moving water due to air trapped inside the pump casing, explaining the issue behind the question: How does a pump lose its prime?

A natural, realistic home maintenance scene showing a professional engineer servicing a polished RAFSUN centrifugal water pump connected to white household PVC piping in a residential utility area. The engineer is turned away from the camera with no face visible, using a screwdriver to inspect the pump during a troubleshooting situation related to priming and unstable water flow. The metallic centrifugal pump is the clear focal point, with a softly blurred laundry and home background that reinforces a domestic application setting. This image visually represents the main disadvantage of a centrifugal pump: it cannot handle significant amounts of air or vapor well, which can cause loss of prime, difficulty self-priming, and inconsistent flow during operation.
