3ESS 3" DC NSK Bearing Brushless Solar Screw Submersible Water Pump

Main Features：

●New type screw: High-lift and mass flow.

●Permanent magnet DC brushless synchronous motor:

   1)The efficiency arrives at 115%-120%

   2)Green solar energy and no electric charge

●The whole 304 stainless steel rotor shaft and pump shaft avoid the risk of shaft breakage

●Good wear resistance: stainless steel connector/ oil cylinder 

●Japanese NSK bearing: extend the working life

●Silicon carbide-impregnated graphite 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 180°C high temperature resistant copper wire, insulation class F

●Cold rolled 600 silicon steel sheet stator and rotor
●The magnet is made of 40SH NdFeb, with a temperature resistance of 150°C

●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
