SKD-66 standard type
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.
SKD-66BP standard type
1. It has all the function of SKD-66
2. It can control two water pump at the same time. If the main pump is not enough, it can start the second pump at the same time to meet the users' need.
Main pump: 220v three phase,1.5KW; Second pump: 220V single phase, 1.5KW
Application
two frequency inverter control two water pump
