3EPC 3" DC Brushless Solar Submersible Deep Well Pump

Main Features：

• Permanent magnet DC brushless synchronous motor:

   (1)The efficiency is improved by 15%-20%

   (2)Save energy

   (3)Reduce the consumption of solar panels

• Brass or stainless steel outlet/connector/ oil cylinder for option.
• Japanese NSK bearing: prolong the working life.
• Alloy mechanical seal: Longer working life and high reliability.
• Motor coil is made by automatic winding machine with centralized winding technology, motor efficiency is much improved.
• The pump parts are processed by high-precision and fully automatic machines, strictly controlling the dimension precision and smoothness.
• Intelligent water shortage and full water protection.
• DC Controller:

   (1) Waterproof grade: IP65.

   (2) Ambient temperature: -15℃ to 60℃.

   (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 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) Automatically start and stop working.

   (8) Water proof 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.

• 2 years warranty.
