How to Fill Foam Concentrate to a Foam Bladder Tank

1.After starting the fire water pump and there is pressurized water in the pipeline, first open the water inlet valve and evacuation valve.

2.Adjust the pressure gauge to display the calibrated working pressure of the foam ratio mixing device and stabilize it at a certain value.

3.When the pressure water enters the storage tank and the pressure rises to the working pressure, the foam outlet valve  can be opened, the foam mixture is automatically adjusted to 6% or 3%, and the foam mixture starts to be output to the system.

4.When the liquid supply is stopped, the foam outlet valve should be closed first (to prevent the pressure water from pouring the liquid into t he foam liquid rubber bag) and then close other valves. At the same time, the pump should be terminated.

5.Method of first filling foam liquid: a. Close the water drain valve and foam discharge/filling valve; b. Open the flange cover of the foam liquid filling port, and the foam liquid can be manually filled into the capsule, or the electric liquid filling pump can be used to inject the foam liquid from the foam discharge/filling valve ; c. When the foam liquid overflows from the filling port, it can be considered that the foam liquid has been filled.

6.When testing the water, open the water inlet valve  and evacuation valve, close other valves, and pass in pressure water. When the evacuation valve sprays water, it can be closed to make the storage tank in Standing status.
