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.
Key Features
-
Self-Priming Function:
-
Eliminates the need for manual priming.
-
Once filled initially, it can automatically draw water even after air enters the system.
-
-
Smart Control System:
-
Equipped with pressure and flow sensors for automatic start/stop.
-
Turns on when a tap is opened, and shuts off when closed.
-
Prevents frequent cycling with electronic pressure switch control.
-
-
Motor & Build:
-
Single-phase AC motor (220V, 50/60Hz) with copper winding.
-
Built-in thermal protector to prevent overheating.
-
Pump body typically made of cast iron or aluminum alloy, with brass or stainless steel impellers for durability.
-
-
Performance Specs (typical ranges):
-
Power: 0.37KW .
-
Flow rate: 35L/MIN.
-
Head (pressure): 35 M.
-
DEPTH: 9M.
-
Liquid temperature range: –10 °C to +35 °C.
-
-
Safety & Reliability:
-
Dry-run protection (stops pump if no water is detected).
-
Delayed start (≈3s) to prevent electrical sparks.
-
Anti-rust treatment on pump body for long service life.
-
Periodic self-activation (e.g., every 72h for 10s) to prevent pump lock-up during long inactivity.
-
Applications
-
Household water supply boosting (low-pressure taps, showers).
-
Smart garden irrigation systems.
-
Light commercial water distribution (small offices, shops).
-
Cooling/air conditioning systems (specialized models).
Advantages
-
Automatic operation saves effort and ensures consistent pressure.
-
Energy-efficient design reduces electricity costs.
-
Low noise compared to traditional booster pumps.
-
Durable construction with stainless steel/brass impellers and anti-rust coatings.
Considerations
-
Initial priming required (pump chamber must be filled with water before first use).
-
Voltage compatibility (220V AC).
-
Sizing matters: Choose a pump with flow/head capacity matching your household or irrigation needs.
-
Maintenance: Periodic cleaning and inspection of seals and impellers extend lifespan
