Description: The solar brushless pump adopts the hall element with high sensitivity and low power consumption, and is driven by the efficient and intelligent electronic circuit, and adopts the volute design in fluid mechanics for the impeller cavity to reduce the resistance of water flow, so as to improve the comprehensive performance by 20% compared with the traditional solar water pump.Also solved the current brushless solar water pump is difficult to start, low efficiency, poor stability.The pump can be connected with various different shapes of sprinkler head, spraying different water types. Solar panel specifications:Rated voltage: 7VRated power: 1.4W Material: monocrystalline silicon, rubber plateWater pump specifications:Working voltage: DC 7VWorking current: 160MAMaximum lift: 100CMMaximum flow: 190L/Hpump life: > 20,000 hourspump noise: < 45DB Product performance:Water spraying height: 30-60cm, connected with different sprinkler head, the height of water spraying will be different.When the solar panel receives enough sunlight, the pump will be switched on in three seconds. Usage:Assemble the product according to the schematic diagram.Place the solar panels in a suitable place to ensure that they are not obscured by other objects.When the solar panel receives sufficient light, the pump is working normally.When the pump is just put into the water, there is air in it, which may affect the effect of spraying water.After the water pump is normal, connect the sprinkler head.
