This device features stable pressure, non-frequent operation, high efficiency, energy saving and low noise, which can be used to replace traditional high-positioned water tanks or water towers.
-24 hour constant and pressure and automatic activation of auxiliary pumps according to pressure signals.
-Smooth start, which eliminates water hammer and extends the service life of motors and pumps.
-Protection against under or over voltage, overcurrent, overheat, overpressure as well as no-load of water
-Optional functions available on customer’s demand, such as motors in-turn running, sleep mode, etc.
-Digital PID control, which is better than PLC logical control
-Stable operation and easy handling due to high automation and intelligence level
-100% factory tested with very low failure rate
Constant pressure water supply
-The pressure of pipe network is controlled within a certain range
-The pumps work by turns according to the present timing. The operation time for each pumps is roughly equal to prolong the service life of the device.
-Working pressure values in different time can be set to meet the demand of water supply
-The device goes into sleep mode for energy-saving during the night or the water consumption is very few
-When the pressure of water network reduces to the preset value, the device will be wake up automatically and start to operate
-In the event of an inverter failure, the controller will reset the inverter automatically. If the reset time is more that preset number, a display of inverter failure will be generated by the system. Maintenance of the inverter is necessary.
