For a large area or a lot of protection sites and more dispersed situation, if the use of the sac pressure proportional mixing device, the need for a lot of quantity, not only covers a large area, and the initial foam liquid storage capacity is also a lot, in this case, the use of mechanical pump remote injection, can greatly simplify the system, and greatly shorten the water-foam conversion time. The foam can be injected hundreds of meters away. Even for non-Newtonian fluids such as anti-soluble foams or fluorine-free foams, remote injection is completely possible as long as accurate hydraulic calculations are performed.

Water driven proportioner remote injectioncan be widely used in underground garages, coating plants, dangerous goodswarehouses and other foam-water spraying systems.
