1、Overall Structure: DC screw pump can convert the electricity generated by solar panel to drive the pump work, beautiful appearance, cast iron motor barrel, high accuracy shell painting, stainless steel material filter, effectively stop the debris into the pump and damage the motor. 2、Tetrafluoroelastomer Mechanical Sealing: DC screw pump is with good sealing performance, low loss, carbon brushes with good commutation performance, good conductivity and heat conduction as well as lubrication performance. 3、All Red Copper Core Brush Motor: DC screw pump has good wear resistance and high efficiency. All red copper core brush motor, stable power output, quieter operation. Permanent magnets, extended magnets, forward and reverse rotation without burning the machine. 4、High Pressure: DC screw pump is easy to install, use and maintain. Stable performance, high flowing, high pressure, strong anti corrosion ability. 5、Working Process: DC screw pump is ideal for domestic and utility applications where surface water pressure is insufficient to transfer water from one place to another. 6、Wide Usage: DC screw pump can be used for farm irrigation, garden irrigation, water lifting projects, water extraction for farming, water extraction from wells, homes, villages, farms, agricultural irrigation gardens, etc.
