Wholesale 4EPC 4 Inch DC Brushless Solar Pump With Plastic Impeller Supplier, OEM/ODM Company

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 bearing: 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
