What are the advantages of DIFFUL DC solar pumps?

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. Brass or stainless steel outlet/connector/oil cylinder.

4. Japanese NSK bearing: prolong the working life.

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 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. Controller:

    (1)   Waterproof grade: IP65

    (2)   Ambient temperature: -15℃~60℃

    (3)   MPPT function, the solar power utilization rate is higher.

    (4)   Automatic charging function:Guarantee the pump normally working, meanwhile charge the battery; And            when there is no sunshine, the battery can make the pump continuously working.

    (5)   LED displays the power,voltage, current, speed etc working condition.

    (6)   Frequency conversion function:It can automatically run with frequency conversion according to the solar          power, and user also can change the speed of pump manually.

    (7)   Automatically start and stop working.

    (8)   Water proof and leak-proof:Double seal effect.

    (9)  Soft start: No impulse current,protect the pump motor.

    (10) High voltage/Low voltage/Over-current/High temperature protection.
