DIFFUL DC Brushless Solar Submersible Pump with S/S impeller Advantage:

1. Permanent magnet DC brushless synchronous motor: The efficiency is improved by 15%-20%; Save energy; Reduce the consumption of solar panels.

2. 304 S/S pump shaft.

3. 304 S/S impeller and oil cylinder: not easy to wear, corrosion-resistant.

4. Japanese NSK bearing, the working life will be 3 to 5 times prolonged.

5. Double bearing motor base can work under more axial pressure

6. Alloy mechanical seal: Longer working life and high reliability.

7. Motor coil is made by an automatic winding machine with centralized winding technology, motor efficiency is much improved.

8. Intelligent water shortage protection: The pump stops working automatically when there is no water in the well, and automatically start working 30 minutes later.

9. MPPT Controller: the solar power utilization rate is higher. It also features automatic charging, frequency conversion, automatic power on/off, soft start, and high voltage/low voltage/overcurrent/high temperature protection.
