Bladder Tank Foam Proportioning System
Foam Bladder Tanks offer a reliable and simpler method of foam proportioning. The Bladder Tank system includes a pressure-rated tank with an internal elastomeric rubber bladder.
Upon system actuation, incoming water applies pressure to the rubber bladder, which supplies pressurized foam concentrate to the foam proportioning device (ratio controller).
The foam ratio controller meters the foam concentrate into the fire water line, creating a foam solution.
The solution is then piped to the discharge devices protecting the hazard area. Bladder tanks are available in horizontal and vertical mounting with a completely pre-piped option.
Fujian Haijing Fire Fighting Equipment Co., Ltd. is one of the leading manufacturers and suppliers of bladder tank foam proportioning system in China, also supports customized service. Please feel free to wholesale cheap bladder tank foam proportioning system from our factory.

What routine test is unique to bladder-tank proportioning?
An annual "draw-down test": open the test valve on the proportioner, collect foam solution for 30 s, and use a refractometer or conductivity meter to confirm the design percentage (e.g., 3 % or 6 %) is within ±10 %.

Q&A
Q: How does a Bladder Tank Foam Proportioning System work?
A: The foaming agent is stored in a tank separate from the water, and the two become mixed within the piping system before discharge. At the end of the piping is a nozzle or sprinkler. When the water mixes in with the foaming agent, then a foam-water mixture occurs and is discharged onto the fire.
Q: Should a bladder tank be full of water?
A: Yes, a bladder tank is supposed to have both water and air in it, with the air contained in the bladder and the water filling the rest of the tank. The air inside the bladder is compressed and expands as water is pumped into the tank, creating a steady pressure and flow for your system. If a bladder tank is full of water and feels light, or if you hear frequent "snaps" from the pump, it may be waterlogged, indicating a ruptured bladder.
Q: How do you know what size bladder tank you need for your well?
A: Find your pump's flow rate (GPM)
The pump flow rate, measured in gallons per minute (GPM), indicates how much water your well pump can deliver. This is critical for determining the tank size, as a tank that's too small for your pump will cause frequent cycling, leading to premature pump failure.
