Operating principles

The intensifier pump consists of a hydraulic system, a
high-pressure water delivery system, and a control
system. Details of the control, hydraulic oil and high-
pressure water systems can be found in the intensifier
pump manual.

The water is pressurized by using the fluid pressure in-
tensification principle. Hydraulic oil pressure acting on
the piston results in a force on the plunger, which pres-
surizes the water in the small chamber. Force equilib-
rium is achieved when the water pressure equals the
hydraulic oil pressure times the effective area of the pis-
ton divided by the area of the plunger, assuming no fric-
tion losses. The ratio of the effective piston area to
plunger area is defined as the pressure intensification
ratio.
