Features 1Solar Water Pump: The electricity generated by the convertible solar panel drives the water pump to work, the solar PV water pump has high efficiency, stable and reliable. 2Durable Materials: Cast iron motor barrel, with painted shell, corrosion resistant, and stainless steel filter screen can effectively prevent debris from entering the pump. 3Stable Operation: All copper motor and high accuracy bearing are used to ensure stable operation and low loss, the carbon brush has good steering effect and good conductivity. 4Excellent Parts: Brushed DC screw pump has large flow, stable power output, excellent permanent magnet, stator and extended magnet, and supports CW and CCW without burning. 5Multiple Usages: The DC submersible pump can be used for river water intake, garden irrigation, water lifting engineering, underground water intake, camping water supply, aquaculture, etc. Specification Item Type: Submersible PumpModel: ZQB 24Material: Stainless Steel, Copper, Tetrafluororubber, Cast IronRated Power: 180WRated Flow: 3 m/hRated Lift: Approx. 25 meter / 82ftOutlet Diameter: Approx. 25mm / 1inMotor Speed: 3500r/minPump Size: Approx. 78 x 380mm / 3.1 x 15in (Including Joint Size) Package List 1 x DC Screw Pump1 x 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 during 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 contact4. The lifting and release of the electric pump shall be tied to the elevator and placed by hand, without pulling 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 blocked6. After 500 hours of power on operation, remove the pump for maintenance, check the seals, clean the brush powder of the torsion converter, and replace the bearing grease and carbon brush7. 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 panel9. The water depth of the pump shall not exceed m, otherwise the water pressure is too high and the oil sealing cannot bear it, which will lead to water ingress into the motor (household electricity is strictly prohibited)
