2ESS Series DC Brushless Stainless Steel Screw Pump for Agricutural

Main Features：

●Advanced screw design: Elevated lift and optimized flow.

●Permanent magnet DC brushless synchronous motor:

   1)Attains an efficiency level of 115%-120%.

   2)Utilizes eco-friendly solar energy and eliminates electric charging.

●Entire rotor shaft and pump shaft crafted from 304 stainless steel mitigate the 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 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 offer professional after-sales service and extended warranty period.
