Advantages

• Driven just by the water flow. No electricity is required, thus preventing additional load to the vehicle’s power supply.
• The specially designed pump allows keeping the proportioning rate at all water pressures, even if they vary.
• The selected proportioning rate is instantly and precisely at hand whenever the next job starts. Here is why: The water motor’s number of revolutions is determined directly by the current water flow rate. Whereas, an electric motor would have to adjust the number of revolutions first.
• Flushing can be skipped: After operation, the foam/wetting agent can remain in the proportioning pump and is even supposed to do so. One more reason why the set proportioning rate is available instantly and precisely when operation is started again.
• Course and length of the hose lines on-site play no role since the water pressure has no influence on the proportioning rate.
• Perfectly suited for aerial/turntable ladder trucks: The height difference between proportioner and discharge device does not matter as the specially designed proportioning pump works independently of the backpressur.
• Also suitable for alcohol-resistant and fluorine-free foam agents with a very high viscosity as we have dimensioned the proportioning pump especially for this challenge.
• Suitable for all discharge devices:
  – Jet spray nozzles with/without a foam attachment.
  – Medium, heavy and adjustable foam nozzles.
  – High-expansion foam generators.
  – Monitors.
