1.2 Functional Description
The SL-IV Waterjet Pump meets the automotive and industrial markets needs of
low to high volume production of water jet pumps. The maximum HP water
pressure is limited by a hydraulic relief valve that is factory certified and sealed.
No HP rupture disk is required.
HP water is produced by an intensifier consisting of two HP water cylinders
mounted to a hydraulic cylinder. Ceramic plungers (2 per intensifier) attach to
the hydraulic piston and extend into each HP cylinder. With two intensifiers
mounted on one SL-IV frame, both may operate simultaneously (dual) or one
may serve as stand-by for the other (redundant). Piston travel is sensed
electronically by proximity switches which control hydraulic flow to/from the
double-acting hydraulic piston/cylinder.
Refer to Table 1-2 for HP water performance limits for various power levels of
SL-IV waterjet pumps.

The recirculation hydraulic loop for cooling and filtering oil runs continuously
whenever the motor is running.
