◀◀ Key Selling Points ▶▶

✅ Unmatched Efficiency: PMSM technology maximizes energy conversion (>90% motor efficiency) and reduces startup power needs.
✅ Smart MPPT Control: Dynamically adjusts to sunlight variations for 30% higher yield than conventional pumps.
✅ Extended Lifespan: 3× more durable than AC pumps, with premium stainless-steel construction resisting rust and abrasion.
✅ Comprehensive Protection: Auto-shutdown safeguards against over-load, under-load, rotor lock, and overheating.
✅ Oil-Cooled Design: Ensures stable operation in harsh environments (up to 60°C ambient temperature).

Why Choose This Solar Pump?

Engineered for zero-maintenance operation in harsh conditions, our screw pump converts sunlight into relentless water pressure without fuel costs. The MPPT controller ensures peak performance even on cloudy days, while stainless-steel components withstand sand, silt, and saline water. Backed by 4-layer rotor protection, it’s the ultimate off-grid water solution.
