The elimination of lubricating oil within the mechanics of the pumps removes the requirement for piston sealing  which in turn reduces the requirement for servicing of seals in the high cyclic loaded components.  Potential contamination of the lubricating fluid and hence pump failure is removed but even more important for the fire industry the  potential of the lubricating oil to contaminate and enter the pumped fluid is totally removed.  The 9 piston design combined with direct 4 pole motor operation produces a very smooth output flow and removes the requirement  for output accumulation or pulsation damping. Pressure ripple-free performance against a fixed orifice make the product ideal for fire  fighting applications. System component fatigue is rare due to the smooth low noise performance of the advanced technology. Light weight and compact design reduces powerpack size and the all 316L Stainless steel construction ensures exceptional corrosion  resistance and unsurpassed life expectancy even in harsh environments.
