Many fire scenarios require foam or wetting agent for successful extinguishing. To produce these extinguishing agents, the foam/wetting agent must be admixed to the water flow at high precision.
This is what makes the FireDos product concept outstanding: The specially designed water motors and proportioning pumps work flow-proportionally, allowing precise proportioning across a wide range of water flow rates and pressures.
- The water motor (1) is driven by the extinguishing water flow which passes through it.
- In turn, the water motor drives the proportioning pump (2). This pump pulls in the foam agent and delivers it into the extinguishing water pipework.
- Switching the ball valve (3) between suction of the foam agent and flushing mode.
