A self-priming AC booster pump is a centrifugal pump designed to automatically remove air from its suction line, allowing it to lift water from below its inlet without manual priming. It is widely used in household water boosting, irrigation, and light commercial applications where consistent water pressure is needed.
⚙️ How It Works
-
Initial Filling: The pump casing must be filled with water once during installation.
-
Air Evacuation: As the impeller rotates, water recirculates inside the casing, pushing air out through the discharge.
-
Vacuum Creation: The removal of air creates suction, drawing water up from the source.
-
Continuous Operation: Once primed, the pump maintains water flow even if air enters intermittently.
🔧 Key Features
-
