What is the main purpose of priming a pump?

The primary purpose of priming a pump is to replace air with water inside the pump. When a pump is operated, it must be filled with liquid to create a hydraulic seal that allows it to function properly. If air is present, it can obstruct the flow of liquid and negate the pump's ability to create the necessary suction force. By priming the pump, the air is removed and replaced with the liquid that the pump is intended to move, enabling it to operate efficiently and effectively.

This process is crucial because without proper priming, the pump can run dry, leading to damage or inadequate performance. Priming ensures that the pump has the necessary fluid to start its operation and maintain consistent flow and pressure in the system.
