0.4 Hp Solar Water Pumps

Listing ID #671990

We are offering 0.4 hp solar water pumps.
Product desciption
patented new design solar dc system by this year.
The whole system include:
1 poly-crystalline solar panel
1 charge controller
1 dc pump
full set of liquid level monitors.
We also provide design works for the solar pump system by free.
Technological innovation:
a. 25% increase on efficiency by applying dc pm motor of brushless and sensorless, in comparison with traditional ac motor.
B. Great improvement on safety and reliability of motor through application of stator and rotor casting resin sealed technology to ensure motor's insulation resistance above 300mã�â© .
C. To easier installation and higher environment protection by using water lubricated bearing instead of traditional oil lubricated bearing.
D. Multiple liquid level monitors prevent the pump system from the following conditions: when the water level above the sink, or the water level too low that pump unable to pump water.
