Description

5 inches Solar Submersible Stainless Steel Borehole Pump with Low Noise and NSK Bearing

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.led display shows various data such as power,voltage,current,speed and error code etc.
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:-15ºc~60ºc
(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)waterproof 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 10.2 years warranty.

Reliable performance with easy installation features.
