Automatic pump controller Automatic pump controller Water pump electronic pressure controller can replace the complicated installations of automatic water pump e.g. pressure gauge, pressure switch, T-valve, check valve and pressure tank ). It has the features of stable performance, low maintenance and long lifespan. 1). Economic automatic Water pump pressure switch used in water systems. 2). It starts the electric pump automatically after a pressure decrease(taps opening) and stops it when the fluid flow interrupts at the maximum pressure level of the electric pump(taps closed). 3). Joint screw: G1" 4). Completely replaced traditional pump control system composed of pressure switch, pressure tank and check valve, etc. 5). Stop the water pump in the case of water shortage. 6). Customized setting.
