4ELR 4" DC Brushless Solar Pump With Plastic Impeller

Main Features：

●Permanent magnet DC brushless synchronous motor:The efficiency is improved by 15%-20%.

●Environmentally friendly: As we all know,The pump is powered by solar energy,making it an eco-friendly and cost-effective solution for your water pumping needs.

●Two textures for options: Brass or stainless steel outlet/connector/ oil cylinder for option.

●Japanese NSK bearing: Elongate the running life.

●Silicon carbide-impregnated graphite mechanical seal: Ensures maximum durability and efficiency.

●Motor coil is made by 180°C high temperature resistant copper wire, insulation class F, 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: Adjust the pump's speed and flow rate.

●The magnet is made of 40SH NdFeb, with a temperature resistance of 150℃.

●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: At the time there is no sunshine, the battery can store the energy to make the pump continuously working.

    5) LED displays the power, voltage, current, speed etc working condition and error code,and so on.

    6)Suit your specific needs: It can automatically run with frequency conversion according to the solar power, and users also can change the speed of pump manually,and automatically start and stop working.

    7) Water proof and leak-proof: Double seal effect.

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

    9) High voltage/Low voltage/Over-current/High temperature protection.

10)Automatic startup and shutdown, without personnel on duty.

11)Wide open circuit voltage range.

●2 years warranty.
