PHYM tank pressure foam system

First, the product description PHYM series pressure proportioning device consists of a pressure tank, capsules, proportioner, safety valve, check valve, pressure gauge, check valve and piping components. Water supplied by the pump pressure, the foam liquid by mixing with water into a foam mixture of apparatus, since the capsule separates the foam liquid with water, foam liquid once did not run out, next time you can continue to use, and mixing accuracy and stability, reliable. Second, the principle when the pressure part of the water flowing through the proportioner pressure water (3% -6%) from the manifold into the foam concentrate tank squeeze capsules, the replacement of foam concentrate and another portion of the same amount of water (97% -94 %) were mixed in the ratio of the mixture supplied to the mixer to a foam bubble generating means for generating an air bubble out the fire.
