A professional mechanical room scene showing a RAFSUN water pump being inspected for an airlock condition. The image features a blue centrifugal pump with the motor running, visible air bubbles inside the pump casing, and a pressure gauge failing to build pressure near zero. A technician wearing safety gear uses a flashlight to diagnose the system, while only a weak flow of water exits the outlet. This visual clearly demonstrates how to know if a water pump has an airlock, including symptoms such as running motor, no water flow, abnormal noise, and loss of pressure.

A detailed industrial scene showing a RAFSUN centrifugal water pump experiencing airlock inside a mechanical room. The image features a blue centrifugal pump with visible turbulence and trapped air bubbles inside the casing, while a technician wearing safety equipment inspects the system without revealing his face. This visual explains why a centrifugal pump cannot handle air, as air is far less dense than water, preventing the impeller from generating sufficient centrifugal force to create suction, resulting in loss of prime, airlock, and complete flow failure in water pumping systems.
