Zhejiang Dingfeng Electric Co., Ltd. is specialized in producing solar water pumps for more than 25 years. Water pumps are sold to more than 80 countries and regions around the world.
Ethiopia is a country with agriculture and animal husbandry as its main economic source. DIFFUL solar pumps have a large sales market there.
An Ethiopian customer purchased a solar submersible pump model 3DSC4-50-48-400 for agricultural irrigation.
3-inch DC brushless solar submersible pump with S/S impeller
Max. Flow: 4m³/h
Max. Head: 50m see details>>
DIFFUL Solar submersible pump 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 S/S outlet/connector/ oil cylinder.
4. Japanese NSK bearing, the working life will be 3 to 5 times prolonged.
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.
