The automatic controller for water pump is an intelligent pump control device installed on the pipeline. It can start and stop the pump according to the varied data such as water resource condition and pipeline pressure it detected. It can completely replace the traditional system constructed by pressure tank, pressure switch, water shortage protection devices, check valve and four-way valves. The complete isolation between live parts and pipeline as well as high leak-proof control box enables the controller to possess an incomparable security against traditional system. The particular patented check valve device can prevent the possible surging in the system. Pressure gauge shows system pressure variation and its inlet and outlet are assembled in 90°right angle. The starting flow is 80-160L/h and can satisfy any need for home and garden sprinkling irrigation application. Technical parameters
