1. Frequency conversion unit is used for drinking water or non-potable water piping systems with constant pressure.
2. Open the water pump when water begins flowing or the pressure begins reducing(taps open), and close the water pump when water stops flowing(taps close). According to the pressure of system, it adjusts the running speed of pump motor to keep constant pressure.
3. According to the water consumption, it can adjust the power of pump automatically to realize the energy efficiency.
4. Stop the pump automatically when it is short of water.
5. The integrated design doesn't need other electrical accessories, besides it configures LED displaying the pressure to make installation and maintenance more easier.
6. Having the buttons of on-off.
