FOAMJET xxxM – Balance Pressure digital direct injection foam proportioning system is used to maintain selected constant foam-water proportion regardless of water flow fluctuations. The system accurately delivers foam concentrate from 0.1 % to 8 % through electric metering valve directly into the water discharge stream. Differencial pressure relief valve always maintains the foam pressure about 1-2 bars above the water pressure and returns the excess of the foam into the foam tank. The system uses high quality industrial components. Foam pump can be driven by PTO or hydraulic motor.
