Drawing 37 full load amps at 460 Vac or 74 full load amps at 230 Vac, 30 hp Model iP60-30 produces 0.6 gpm of ultra-high pressure water at continuous operating pressure of 55,000 psi. Tie-rod design eliminates threads on high pressure cylinders, end caps, and hydraulic cylinders, while matched metal components prevent galling of hydraulic components. Pump includes hydraulic accumulator which provides smooth hydraulic pressure, minimizes spikes, and prolongs pump life.
