True 18 GPM @ 4000 PSI with 5/8" Hose = 20% More Cutting & Flushing Water Power at the Nozzle, 32% More Nozzle Horsepower @ Max PSI! (See Chart Below!)
Sources & Resulting Chart: Using StoneAge & Gates Pressure/Flow Calculators
Best in Class of 18 GPM Jetters! Both GPM & PSI! (Adjustable to use virtually any nozzle!)
  • MAX GPM! Out performs all 15-18 GPM jetters at the nozzle with less than 66 HP gas or less than 63 HP diesel! Most only carry about 15 GPM, even when rated up to 18 GPM, (Why? Less GPM = Less Power Needed, 1/2" hose PSI loss is extremely high over 15 GPM)
  • MAX PSI! 76 HP to hold 4000 PSI @ the pump for a true 18 GPM flow = Maximum GPM & PSI achieved at the nozzle - (Overcomes GPM/PSI loss through the hose the best possible way!)
  • 5/8" ID Hose! Field repairable, with 1/2" NPT ends, delivers more nozzle PSI power over standard 1/2" ID hose @ 18 GPM - where it counts! (Gain 612 PSI @ 300', 1020 PSI @ 500', Accesses the true potential of 18 GPM!)
  • Tuned Nozzles: System Tuned for Max GPM / PSI, (Make your cutting / flushing nozzles perform better than ever!)
