Abstract:
Device for continuously preparing constant-proportions solutions with variable flow rates, particularly suitable for preparing foam-extinguisher solutions for fire-fighting systems, comprising a motor device (21), operated by the energy supplied by the same pressure of fire-fighting water network, constituted by a volumetric screw-pump (24), which is made to work in reverse mode, and in its turn is mechanically connected with one or more volumetric pump(s) which meter the fire-fighting foam-extinguisher liquid into the network water.
