Main Features:

●Permanent magnet DC brushless synchronous motor:

   1)The efficiency arrives at 115%-120%

   2)Green solar energy and no electric charge

   3)Reduce the amout of solar panels so that reduce footprint

●Good wear resistance: stainless steel connector/ oil cylinder 

●Japanese NSK bearing: extend the working life.

●Alloy mechanical seal: It protects the motor because the seal is able to keep out water and other impurity 

●Winding technology: Motor coil is made by automatic winding machine and the efficiency is much improved

●New type screw: High-lift and mass flow

●Overload and burn prevention: When there is little water,the pump stop running immediately down to prevent dry burning

●DC Controller:

     1) Waterproof grade: IP65.

     2) Environment temperature: -15℃ to 60℃.

     3) MPPT function, the solar power utilization rate is higher.

     4) Runing stably:The pump normally works at the same as  charges the battery ,which there is little sunshine,the pump can also run stably.

     5) Direct view display: LED displays the power, voltage, current, speed etc working condition and error code.

     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) Easy installation: With widely used DC plug,the pump is easy to install

     8) Water proof and leak-proof: Double seal security

     9) Soft start: No impulse current, protect the pump motor.

     10) Multi-party protection: High voltage/Low voltage/Over-current/High temperature protection.

●2 years warranty: We have professional after-sales service and ultra long term.
