For a large area or a lot of protectionsites and more dispersed situation, if the use of the sac pressure proportionalmixing 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, theuse of mechanical pump remote injection, can greatly simplify the system, andgreatly shorten the water-foam conversion time. The foam can be injectedhundreds of meters away. Even for non-Newtonian fluids such as anti-solublefoams or fluorine-free foams, remote injection is completely possible as longas 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.
