Description：

The 4ESS Series DC NSK Bearing Screw Solar Deep Well Water Pump is an innovative solution designed to provide reliable and efficient water extraction from deep wells using renewable solar energy. Engineered with precision and durability in mind, this pump is the epitome of modern technology and sustainability, perfect for both residential and commercial applications.

Main Features：

●Sophisticated screw design: Enhanced lift and optimized flow.

●Permanent magnet DC brushless synchronous motor:

1)Graciously achieves an efficiency level of 115%-120%.

2)Embraces eco-friendly solar energy and avoids electric charging.

●Entire rotor shaft and pump shaft crafted from 304 stainless steel mitigate the potential risk of shaft damage.

●Superior wear resistance: Stainless steel connector/oil cylinder.

●Japanese NSK bearing: Extends the operational lifespan.

●Graphite mechanical seal impregnated with silicon carbide: This safeguard operates by diligently preventing water and other impurities from infiltrating the motor.

●Winding technology: Motor coil constructed from 180°C high temperature resistant copper wire, insulation class F.

●Cold rolled 600 silicon steel sheet stator and rotor.

●The magnet is fabricated from 40SH NdFeb, with a temperature resistance of 150°C.

●DC Controller:

1) Waterproof rating: IP65.

2) Ambient temperature range: -15℃ to 60℃.

3) MPPT function, enhancing the solar power utilization rate.

4) Stable operation: The pump operates seamlessly even when charging the battery in low sunlight conditions.

5) Direct view display: LED indicators display the power, voltage, current, speed, etc., operating status and error code.

6) Frequency conversion functionality: Automatically adjusts to the solar power through frequency conversion, and users can also manually modify the pump speed.

7) User-friendly installation: Equipped with a widely utilized DC plug, the pump is effortless to install.

8) Waterproof and leak-proof: Double seal security.

9) Soft start: Prevents impulse current, protecting the pump motor.

10) Multi-party protection: High voltage/Low voltage/Over-current/High temperature protection.

●2 years warranty: We extend our professional after-sales service and extended warranty period.
