4EFS Series 4" AC/DC Water Filled Hybrid Stable Mechanism Design Solar Pump

Description :
EDWIN PUMP provide 4EFS Series 4" AC/DC Water filled motor Hybrid Solar Pump . We have 3 choices for control box.

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. Hybrid powered by AC and DC, max power is 3KW

5. Soft start : extend the service life.

6. Voltage range : 60-380VMP or 90-240VAC, 50/60Hz. Max. VOC is 440V

7. 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.

8. 304 Stainless steel material : It is made from high-quality materials that are resistant to corrosion and rust.

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

10. 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

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

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

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