Description :
EDWIN PUMP provide 4EFS Series 4" AC/DC Water filled motor Hybrid Solar Pump .

Key features :

1.Permanent magnet brushless frequency conversion water-filled motor Frequency control : Small starting current, great starting power, variable frequency speed regulation, the same power brushless motor is more portable

2. Stable mechanism design : Double inner and outer shielded motor with field-oriented control function. No mechanical seal is used, so it can avoid the water leakage and mechanical seal friction. And the wet rotor cooling effect is better.

3. Built-in intelligent controller.

4. Soft start : extend the service life.

5. Special consideration is given to the aspects of Dry-running protection, Reverse protection, Over-load protection, Over-current protection, Over-voltage protection, Phase loss protection.

6. 304 Stainless steel material : It is made from high-quality materials that are resistant to corrosion and rust.

7. High temperature copper coil , use vacuum dip paint insulation treatment process .

8. High-accuracy rotor with graphite bearing and thrust bearing : The advantages of graphite bearings are mainly manifested in: self-lubrication, high temperature resistance, corrosion resistance, light weight, etc

9. In DC mode, the MPPT can be more effective, even up to 99%

10. In AC mode, the power factor exceed 0.99 in case of power factor correction function

11.Dive deeper : Submerging depth can reach 150 meters.

12.2 years warranty
