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 3,400 bar (50,000
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.
