A fully mechanical, automatic around-the-pump foam proportioning system is available for the R600. The system is designed to suit the pump's output characteristic and is embedded in the pump.

Water metering valves are actuated in direct proportion to the water flow rate. The actuation is conveyed mechanically and used to open and close the foam proportioning valve. The current proportioning rate is visualized by means of a cam disk. A maximum of 3 proportioning rates is supported.

• Perfectly geared for the R600
• Excellent foam compound suction capacity
• Completely maintenance-free
• Fully mechanical proportioning system
• Up to 3 different proportioning rates
• Proportioning rate does not depend on pump capacity or pressure
