Hydraulic system
The primary motor runs the primary hydraulic pump, which pressurizes fluid from the hydraulic fluid tank. The
pressurized hydraulic fluid passes through the primary hydraulic manifold, which contains a shift valve that
delivers hydraulic fluid to alternating sides of the intensifier.
Low-pressure supply water enters the high-pressure cylinder in the intensifier, where the piston compresses the
water to make high-pressure water for piercing or cutting.
Hydraulic fluid from the hydraulic center section in the intensifier returns to the hydraulic fluid tank through the
primary hydraulic manifold.
The cooling loop keeps the hydraulic fluid at its optimum temperature. A gear pump moves hydraulic fluid from the
hydraulic fluid tank and sends it through a heat exchanger, where heat transfers through fins to cooling water or to
an optional fan. The hydraulic fluid passes through a hydraulic filter and then returns to the hydraulic fluid tank.
Hydraulic fluid tank
A filler-breather cap keeps the contents of the tank free of airborne contaminants and permits access to the tank
for adding hydraulic fluid. A temperature sensor and a level sensor monitor the hydraulic fluid. A sight gauge
permits observation of the hydraulic fluid level and quality. Suction strainers prevent contaminants from entering
the primary pump and the gear pump.
