Features 1The Power Supply: Can use battery or the electricity generated by the solar panel as power supply, the water pump has cast iron motor barrel and stainless steel filter screen to prevent impurities from entering the pump and damaging the motor. 2Good Performance: Copper motor with good mechanical sealing and high accuracy bearing ensures low noise and low loss, while the carbon brush enables good reversing, good conductivity, heat conduction and lubrication, low wear to the commutator. 3Fine Workmanship: Having increased the flow, the wear resistance and efficiency, the copper core brush motor has stable power output. Also has permanent magnet for the protection against burning in CW and CCW rotation. 4Better in Design: Simple structure, few components, convenient installation, use and maintenance. Stable in work and large in flow, the pressure is higher, and the corrosion resistant. Ideal for places where surface water pressure is insufficient to transfer water from one place to another. 5Wide Application: Can be used for river water intake, farmland irrigation, garden irrigation, water lifting engineering, aquaculture water intake and so on.

Package List 1 x Submersible Pump1 x Water Outlet Connector1 x Sealing Washer1 x User Manual Note 1. Before use, check whether the power supply voltage is consistent with the pump, and the voltage tolerance is +5%. 2. When adding cables for use, the wire diameter shall be sufficient and the extension wire shall be as short as possible. 3. Before use, check whether the bolt is loose, whether the power cord and the insertion cord are damaged or have poor contact. 4. The lifting and release of the electric pump shall be tied to the elevator and placed by hand, do not pull the cable. 5. If there is sand and other sundries in the water, the electric pump shall be placed in a basket or provided with protective measures to prevent the pump from being blocked. 6. After 500 hours of power on operation, remove the pump for maintenance, check the sealing, clean the brush powder of the torsion converter, and replace the bearing grease and carbon brush. 7. Before use, determine the positive and negative poles of water pump and power supply. The positive and negative poles of the water pump shall correspond to the positive and negative poles of the power supply. (Connect the positive pole and the negative pole, press the screw in the socket with a hard object to fix the screw in a positive rotation)8. Check the voltage of the solar photovoltaic panel or battery before use. The voltage of the water pump needs to match the voltage of the solar photovoltaic panel or battery. 9. The water depth of the pump shall not exceed, otherwise the water pressure is too high and the oil sealing cannot bear it, which will lead to water ingress into the motor. (Do not use household electricity)
