1. Inlet flanges: connecting to the air and water pipes of the device separately.
2. Outlet flanges: connecting to piping to be filled
3. Relief valve: stabilizing pressure and preventing overload to ensure constant export pressure.
4. Pressure gauge: indicating the change in outlet pressure.
5. Metering pumps: pressurizing and delivering isolation fluid.
6. Filter: filtering impurities from storage tanks
7. Base frame: fixing and supporting
8. Glass tube level meter: displaying the height of the isolated liquid level in the tank.
9. Liquid storage tanks: storage of isolation fluids
2.2 Operating Principle
Buffer/Barrier Fluid System is mainly composed of isolated fluid storage tank, level gauge, filter,
metering pump and various valves, etc. The device is pressurized by metering pump to deliver the
isolated fluid in the storage tank to the process device, to achieve antifreeze and cleaning effect and
ensure the continuous and stable operation of the process device.
2.3 Packaging
Please take the packaging waste to a special recycling facility.
2.4 Lifting for transport
Please use qualified lifting equipment and lifting straps, and pay attention to safety.
2.5 Storage
Storage temperature -20℃~40℃; storage humidity≤20%.

1. After the installation of the equipment, the first thing is to check the equipment thoroughly and
carefully. The liquid storage tank and pipeline should be purged and cleaned to prevent debris from
entering the pipeline system.
2. When filling the isolation fluid, connect the No. 10 isolation fluid tank with quick-change
couplings as shown in Figure 4. Close valve 2 and slowly open valve 1. Slowly press the antifreeze
solution into the reservoir with compressed air and close valve 1 when the demand is reached.
3. Close valve 4 and open valve 3. Fill the tank proportionally with fresh water and open valve 2. Stir
the solution with compressed air, and close valve 3.

4. Once the above is completed, the outlet pressure adjustment can be made. First, close the valve 5,
and open the valve 7, start the metering pump. After the metering pump runs normally, adjust the
pressure regulator 6 until it is adjusted to the required pressure. At this point you can open the
valve 5 on the system for filling.
5. During the summer months, valves 3 and 5 can be closed and valve 4 opened to directly fill the
system with fresh water, depending on the conditions.
7 Disassembly
7.1 Warnings
Before disassembly, attention should be paid to hazardous process conditions, such as excessive
pressure in the piping.
7.2 Waste removal
Please follow the existing guidelines for waste disposal in your region.
