The bladder tank is a carbon steel pressure vessel containing an elastomeric bladder between the water and foam concentrate, permitting water pressure to be transferred to the foam concentrate without the two fluids mixing together.
Bladder Tanks are positive displacement pro-portioning systems made of a tank and an in-line mixer. The tank is equipped with a bladder that is used to hold the foam concentrate and a mixer is directly piped to the bladder tank. When in operation, water flows into the mixer creating a pressure differential.
All bladder accumulators, sizes 1 gallon and larger, are fitted as standard with two-piece bladder stems with replaceable gas valve cartridge for ease of serviceability. Also, the two-piece stem will accept high pressure military gas valves and permanent mount gauge adapters.
The vertical and horizontal bladder tanks are designed and construct- ed in accordance with the latest revisions to ASME code, Section VIII for unfired pressure vessels with a working pressure of 175 psi and tested to 1.3 times this pressure.

1.625" Silver Filler Cap with Aluminum 4-Hole Bolt-On Bung. If your fuel cell was originally equipped with an aircraft-type fill cap, this kit lets you convert it to an easy-to-use screw-on cap. This is also great for fabricating any kind of tank from scratch.
Bladder accumulators are usually preferred to piston type accumulators for water service applications. Water systems tend to carry more solid contaminants and lubrication is poor. Both the piston and bladder type units require some type of preparation to resist corrosion on the wetted surfaces.
