SECTION 7
HIGH PRESSURE WATER
7 High Pressure Water
The high pressure (HP) water system takes the relatively low pressure water
inlet to up to maximum pressure in excess of 4,137 bar (60,000 psi) supplying
orifice diameters appropriate to the waterjet pump’s operating power (See
Specifications, Section 11).
7.1 Components
The HP water components include the hydraulic intensifier, HP attenuator(s),
HP dump valve, HP pressure indicator (optional), and HP piping.
Maintenance on the intensifier is discussed in detail in this section. In
addition to HP components and assemblies, the hydraulic cylinder features
of the intensifier are discussed in this section. See Section 12 for part number
information on specific components.
