This solar brushless water pump uses Hall elements with high sensitivity and low power consumption, cooperates with efficient and intelligent electronic circuit drive, and adopts a volute design in the fluid mechanics for the impeller cavity to reduce the resistance of water flow, so that the overall performance is better than that of the traditional structure. The efficiency of the solar water pump is increased by 20%. It also solves the shortcomings of the current brushless solar water pump is difficult to start, low efficiency and poor stability. The water pump can be connected with nozzles of various shapes to spray different water types.
