Wholesale 3EPC 3 Inch DC Brushless Solar Submersible Deep Well Pump Supplier, OEM/ODM Company

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
●Silicon carbide-impregnated graphite 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 180 ℃ high temperature copper core,insulation class F, extends the motor's life
●Winding technology：Motor coil is made by automatic winding machine with centralized winding technology, with 180℃ high temperature resistant copper wire, insulation class F
●No dry burning: Intelligent water shortage and full water protection

●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: 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

10)Wide open circuit voltage range

11)Automatic startup and shutdown, without personnel on duty

●Warranty: 2 years of trouble-free service.
