Product Concept
Many fire scenarios require foam for successful extinguishing. To produce these extinguishing agents, the foam 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 between actual proportioning of the foam agent and passing it back to the atmospheric storage tank is done by use of the ball valve (3).
