Four new solar submersible pumps have the following features:
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 outlet/connector/ oil cylinder.
5.Japanese NSK bearing, the working life will be 3 to 5 times prolonged.
6.Double bearing motor base can work under more axial pressure.
7.Alloy mechanical seal: Longer working life and high reliability.
8.Motor coil is made by automatic winding machine with centralized winding technology, motor efficiency is much improved.
9.Intelligent water shortage protection: The pump stops working automatically when there is no water in the well, and automatically start working 30 minutes later.
