Feature:1. Using thickened barrel, hightoughness pressurereducing oil sac, which can protect the normal operation of the motor in a high water pressure environment, realize longlasting work2. Antisand floating impeller is made of engineering plastic, wearresistant and compressive, durable3. Optimized flow channel design, multistage floating rotation bring fast absorption and intake of water4. This water pump uses allbrass core wire motor, which is full of power, high efficient5. Battery solar water pump with largeflow and highlift, with a head up to 55 meters, very practicalSpecification:Item Type: DC Deep-Well PumpMaterial: Brass + engineering plasticsModel: S-4-55Head: Approx. 55meter / 180.4ft(maximum)Flow Rate: 5m/hourWorking Voltage: DC48VOuter Diameter of Interface: Approx. 25mm / 1inCable Length: Approx. 13.5meter / 44.3ft.Package List:1 x DC Water Pump1 x Interface1 x Interface Gasket1 x User ManualNote:1. Check whether the power supply voltage is consistent with the water pump before use.2. If there are debris and other debris in the water source, the pump should be placed in a bamboo basket to prevent clogging.3. The pump must be hoisted with a rope and put on the handle, and the cable must not be pulled arbitrarily.
