1.4W-16CM IntroduceFeatures:1.The solar brushless water pump adopts high-sensitivity and low-power Hall elements, coupled with efficient and intelligent electronic circuit drive, and adopts the volute design in fluid mechanics for the impeller cavity to reduce the resistance of water flow, so that the overall performance is better than the traditional structure The efficiency of the solar water pump is increased by 20 percent . It also solves the shortcomings of the current brushless solar water pumps that are difficult to start, low efficiency and poor stability.2.This water pump can be connected with various nozzles of different shapes to spray different water types.3.Water spray height: 30-60cm, the height of water spray will be different if different nozzles are connected. When the solar panel receives sufficient sunlight, the water pump will start within 3 seconds.4.Create a relaxing environment in your garden. Add fun and joy to your yard or garden.5.Great for pond, bird bath, fish tank, small pond, garden decoration, aquarium, fountains, spout and hydroponic systems and water circulation for oxygen, etc.Specification:Material: ABSColour: blackSize: 16 cmSolar panel specifications:Material: monocrystalline silicon, epoxy resin boardRated voltage: 7VRated power: 1.4WPump specifications:Working voltage: DC 7VWorking current: 160MAThe highest head: 100CMMaximum flow: 180L or HPump life:> 20000 hoursPump noise:
