A fully mechanical automatic around-the-pump foam proportioning system is available for the N / NH series pumps. The unique feature about it: the system is fully embedded in the pump.

• Very easy operation
• Integrated with control system
• Excellent foam compound suction capacity
• Completely maintenance-free
• Fully mechanical proportioning system
• Up to 4 different proportioning rates for a single pump:
  three for normal and high-pressure operations
  an additional rate for high-pressure-only operations
• Supported proportioning rates of 0.5%, 1%, 3% and 6% can be freely combined
• Proportioning rate does not depend on pump capacity or pressure

The HP-FIXMIX around-the-pump foam proportioning system is available for foam generation, using the high-pressure pump. The high-pressure proportioning system can be used in a stand-alone setup or in combination with the normal-pressure proportioning system.

An NH pump can support up to seven different operating states
