The pump automatic controller is a full electronic intelligent water pump control equipment. It starts and stops the pump according to the detected water source status, pipeline water consumption, and pipeline pressure change data. It can completely replace the traditional pressure tank, pressure switch, water shortage protection device, check valve, four-pass etc. system. The complete isolation of the live parts from the pipeline and the high tightness of the control box allow the controller to have a safety that cannot be compared with conventional systems. The integrated design allows you to save more time and materials during installation. It is suitable for the automation of home, unit supply, drainage system and garden irrigation and irrigation of greenhouse plants. Automatically maintain pressure in the pipeline. When the water valve is opened, the power of the water pump is automatically turned on, the water valve is turned off, or the water supply is automatically turned off when there is a shortage of water.
