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、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.
