7V 1.4W Garden Solar Floating Fountain Brushless Water Pump Garden floating fountain is a solar-powered decorative fountain. It is made up of highly efficient solar panel and brushless pump, start-up fast, efficient and stable. Placing the pump in the water without external battery or electric outlet. Add fun and joy to your yard or garden with this amazing solar powered fountain pump kit. As you can see, the solar power fountain can be used in garden, yard, park, and every where have a pond. Not only can decorate the place, exposure the garden, yard, park to the mist, looks like breaking into the fog forest, add a mystery, attract people's eyes. The most important is it can add oxygen to cultivate the fish in the pond, increase the survival rate of fish. How to Use: 1. Assemble the product according to the sketch map. 2. Put it on the water and make sure that the solar panel is not sheltered from the sun. Then it will work normally as soon as the sunshine is enough. 3. There is some air in the pump at the moment that it is put in the water. You'd better not connect the spray head to the pump until it sprays normally. Feature: Start automatically in 3 seconds when sun exposure Purify the air and increase the humidity Start-up fast, efficient and strong stability Built-in DC brushless motor with longer service life and lower consumption Specification: Color: black Solar panel power: 1.4W Power of pump: 1.12W Pump power consumption: 7V 160MA Diameter of solar panel: approx 16cm / 6.3" Diameter of pump: 6mm Spray height: 30-50cm (different sprayer, different height) Maximum flow: 180 L/H Woking life: more than 10000 hours Package Include: 1 x Solar Water Pump 4 x Nozzles 1 x Nozzle Base 1 x Connection Head 1 x Outlet 1 x English User Manual Note: 1. The pump is driven directly by the sunlight, so it will work continuously only when the sunlight is enough. As the power of the solar panel is depended on the sunlight, the pump is also affected by weather, seasons, places, etc. 2. Don't make the pump work without water for a long time, or its lifespan will be shortened. 3. Clean the pump regularly. If it's duty, it will stop working. 4. Be careful when using it. And don't let children play with it.

When we deal with any mechanical engineering system, it needs great consumption of electricity and in the era of energy crisis, effective use of energy sources is must. Country like China and India are the biggest users of energy sources and mechanical equipment like pump has very wide range of applications in industry as well as domestically. In order to save energy one of the most preferred ways is to improve performance of the device for the same energy consumption. In this work focus is on the impeller of the mixed flow type submersible pump. In order to improve the efficiency of the pump need to work at the design level and find the parameters that affects the design and performance of the pump. Here the design of impeller of the mixed flow type submersible pump with the best efficiency point is compared with the existing impeller layout and it is found that the inlet and exit angle of blade and reducing number of blade have significant improvement on the performance of the pump. This improved design impeller will be checked by CFD analysis with existing impeller with same boundary condition.
