4EPC 4" DC Brushless Solar Pump With Plastic Impeller

Main Features：

●Permanent magnet DC brushless synchronous motor:
    1)The efficiency is improved by 15%-20%
    2)Reduce the consumption of solar panels to save energy
●The whole 304 stainless steel rotor shaft avoids the risk of shaft breakage
●Two options: Brass or stainless steel outlet/connector/ oil cylinder for option so that you can make better choose
●Japanese NSK bearing makes longer working life
●Silicon carbide-impregnated graphite mechanical seal: Longer working life and high reliability
●Double bearng: Double bearing structure at the bottom of rotor can withstand greater axial pressure 
●Intelligent water shortage and full water protection.
●Adopt 180°C high temperature resistant copper wire, the class of insulation levels up to Class F
●With solar energy,the innovative pump can live in remote areas where electricity is not available.

●DC Controller:

    1) Waterproof grade: IP65.

    2) Round 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

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

    6) Frequency conversion function:  It can adjust the speed for operation according to the sunlight power, and can also manually adjust the speed for operation according to the actual demand.

   7) Water proof and leak-proof: The motor is bulit to last.

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

   9) It has multi-protections such as high voltage/low voltage/over-current/high temperature protection.

●2 years warranty.
