DCHF DC Brushless SOLAR POWER SURFACE CENTRIFUGAL PUMPS:Solar ground centrifugal pump. The impeller is made of brass. Its main features are low power, low voltage and large water output. High efficiency and continuous working capacity make these pumps very suitable for flood and spray irrigation, horticulture, agriculture, water intake from lakes, rivers and wells, or any industrial application requiring high flow and low head characteristics. The pump should be installed in a closed environment or at least away from bad weather. The pump requires fewer solar panels and batteries, which also reduces the installation cost of the pump.
