water pump pressure control for water pumps

详情

Start and stop water pump automatically according to the pressure and water storage 1. Rate voltage: ******0V, ******0V 2. Max. Current:*0A 3. Frequency: *0HZ**0HZ 4. Max. power:1.1KW 5. Joint screw: G1 6. protection Garde: IP*5 7. starting pressure to choose:1.5bar or 2.2bar The product can replace the complicated installations of automatic water pump ***** pressure gauge, pressure switch, T-valve, check valve and pressure tank). It has the features of stable performace, 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 pressed and wait, with a tap opened till the red light is off. Once released the and closed the tap, the product will keep the pump at its maximum ***** Function: The product is designed especially for all control operation of automatic water pump. If the particular breakdowns occur, suction pipe etc, the product recognizes the breakdowns and the red light failure lights 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 the restart. 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 posesses the features of reset after power failure. Its starting flow is about ****0L/h and is convenient for home application.
