electrical pressure switch pressure control for water pump start and close water pump automatically according ot the pressure and water storage it is wholly electric and intelligentized OPTIONALS: 1.Color. 2.G1'' plastic pipe joint for a quick connection to water pump. 3.Power cable length can choose according to customers' needs. Certification: iso9001; 3C(CHINA); UL(AMERICAN); TUV(GERMANY); CE(EUROPE); ROHSTECHNICAL DATA:1) Rated voltage: 220-240V or 110-120V 2) Max. current: 10A 3) Frequency: 50-60Hz 4) Max. power: 1.1kW 5) Joint screw: 1" 6) Protection grade: IP65 7) Starting pressure: 1.5 bar or 2.2 bar DESCRIPTIONS: The product 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 life etc,. It will indicate the pump has started when the green light Power on lights up after connecting the power. When the yellow light Pump on lights up, it indicates the pump has been started. The pump continues to operate for a few minutes enabling the system to fill in the pipes and to reach the required pressure. If this lapse is insufficient, the red light Failure will light up. In this event, keep the Restart button pressed and wait, with a tap opened till the red light is off. Once released the button and closed the tap, the product will keep the pump at its maximum pressure. High quality PCB NOVEL DESIGN Function: The product is designed especially for all control operation of automatic water pump. If the particular breakdowns occur, such as water failure, obstruction of the suction pipe etc, the product recognizes the breakdowns and the red lightFailurelights up, at the same a stop signal is sent to the pump to prevent damages caused by its working in the absence of water. Rectification of the failures that have caused the blockage, allows the system to be restarted by pressing theRestartbutton. The controller can ensure a constant pressure for the water supplying system and thus reduce the water hammer effect inside pipeline during water delivering. The controller also possesses the features of reset after power failure. Its starting flow is about 36-60L/h and is convenient for home application.
