FM 5130《Foam Extinguishing Systems》2021 has set up a section (4.26) specifically for the hydraulic motor driven proportioners, clarifying the requirements and test methods, which is more stringent than the previous requirements and makes the system m
More >>With the continuous improvement of environmental requirements, the foam concentrate also has C8 fluorocarbon surfactant development to C6 fluorocarbon surfactant, but the final development direction is completely fluoride-free foam concentrate. Fluo
More >>This is a typical balanced pressure proportioning set , the pressure of the system comes from the foam pump. Usually the outlet pressure of the foam pump is 0.1-0.2Mpa higher than the water supply pressure, and then the pressure of the foam concentra
More >>Water-turbine driven pump proportioner ,in the new FM standard ,was called hydraulic driven proportioner which composed of hydraulic motor and foam pump. The hydraulic motor and foam pump are positive displacement fluid machinery, that is, the displa
