The NH series pumps combine all the benefits of the N series pump with those of a four-stage high-pressure centrifugal pump on a single pump shaft.

• No additional drive required for high-pressure pump
  The normal and high-pressure pumps share a pump shaft
• Maintenance-free
  Thanks to complete integration of the high-pressure stage in the normal-pressure pump
• Thrust load compensation
  Counter-rotating design of normal and high-pressure impellers
• No additional seals required despite high-pressure pump
• HP can be engaged/disengaged at any speed thanks to switchover valve
  It is not the HP pump itself, but the water supply that is switched over
• Noise reduction thanks to speed reduction
  Possible due to a four-stage high-pressure unit
