How: Solar water pump dc brushless fountain pumpProduct Description:Solar brushless water pump uses high-sensitivity and low-power hall elements, combined with efficient and intelligent electronic circuits. In addition, the impeller cavity adopts a hydrodynamic volute design to reduce the resistance of water flow, and the overall efficiency is 20% higher than that of traditional solar water pumps. It also solves the shortcomings of current brushless solar water pumps, which are difficult to start, have low efficiency, and poor stability. The water pump can be combined with nozzles of different shapes to spray different types of water. Solar Panel Specifications:Rated Voltage: 7V Rated Power: 1.2W Material: Polysilicon, PET LaminatedSpecification:Working Voltage: DC 7V Working Current: Max Head 150Ma: 100cm Max Flow: 180L/h Pump Life: gt; 20000 hours pump noise: lt; 45dBColor: BlackInner Box Size: 14*14*5cmApproximate Weight: 265cmProduct Performance:Spray Height: 30-60cm. When connecting different nozzles, the spray height will be different. When the solar panel receives enough sunlight, the water pump will start within 3 seconds. Instructions:1. Assemble the product according to the diagram.2. Place the solar panel in a suitable location to ensure that it is not blocked by other objects. When the solar panel receives enough light, the water pump works normally.3. When you put the water pump into the water, there is air in the water that can affect the spray effect. It is recommended to connect the nozzle after the pump sprays water normally. Precautions:1. This product is a direct solar water pump without extra batteries. The height of the spray depends entirely on the intensity of the sun. When the sunlight is dim, the water pump will not work continuously, but will automatically start repeatedly until the sunlight reaches a certain intensity, the water pump will return to the continuous working state. When using, please place the product in the sun without protection. Shading will affect the normal operation of the pump.2. The water pump must be completely submerged in water and must not be dehydrated for a long time. When the pump is submerged in water, because there is air in the pump, it is recommended to insert the nozzle after pressing the pump normally.3 Keep the water source clean and clean the water pump regularly to prevent foreign objects from being sucked into the water pump, causing the water pump to not work normally.
