Frequency inverter

Function: 

1. Frequency controller is used for drinking water or non-potable water piping systems with constant pressure.

2. Open the water pump while the pressure decreasing in the pipes, and it keep constant pressure by adjusting the running speed of pump motor. Close the pump while there is no flow.

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 water shortage.

5. No need other component, integral design and pressure display LED make the unit easily to be installed and maintain.

6. Buttons for start/stop, pressure increase and decrease.

7. Control the second water pump of single phase and no-frequency inverter, form the two pumps unit to promote the flow of water system.

8. Add a button of switchover mode for one pump/ two pumps

OPTIONALS:  

1. Color of product appearance 

2. Power cable or motor cable can be equipped according to customers' requirement. 

3. R1''Plastic Quick Connector

One frequency inverter control one pump
