1. Constant speed pump water supply: Constant speed pump water supply that is, the pump motor speed is constant, by changing the valve opening and the number of pumps into operation to adapt to the changing demand of water users.

2. High water tank water supply: Raise the water level above the user's position when using the water pump to work, store the water source, and use the water source's own weight to form gravity water supply.

3.Air tank water supply: Air tank water supply is the use of water tank to store water, when the user water, through compressed air into the user pipe, with the decrease of water in the tank, the pressure will be reduced.

4. Variable frequency speed regulation and constant pressure water supply:
The pressure transmitter installed in the system compares the pressure signal of the system with the set pressure value, and then stepless adjusts the pump speed by adjusting the output of the inverter through the controller, so that the water pressure of the system is always stable in a certain range no matter how the flow rate changes.
