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% because of multi-stage impeller      2)Save energy by reducing the consumption of solar panels●Two designs for selestion: The material is made of stainless steel or copper for selection●Japanese NSK bearing: Effectively improve wear resistance and corrosion resistance●Alloy mechanical seal: Using one-piece chassis,the pump is well sealed as well as avoids water heater●Full copper core motor : Instead of aluminum cable core,the motor with copper core extends the motor’s life●Winding technology：Motor coil is made by automatic winding machine with centralized winding technology, with high mechanization and high production efficiency.●No dry burning: Intelligent water shortage and full water protection.●DC Controller:      1) Waterproof grade: IP65.      2) Ambient temperature: -15℃ to 60℃.      3) MPPT function: Maximum Power Point Tracking can .      4) Automatic charging function: When there is no sunshine, the battery can make the pump continuously working      5) Clear visual: LED displays the power, voltage, current, speed etc working condition and error code.      6) Frequency conversion function: It can automatically run with frequency conversion and user also can change the speed of pump manually.      7) Soft start: No impulse current, protect the pump motor.      8) High voltage/Low voltage/Over-current/High temperature protection.      9) Easy installation: It is also easy to install and maintain, with no complicated wiring or plumbing required.●Warranty: 2 years of trouble-free service.
