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.

1.4.2 Safety Procedures
Safety procedures must be observed while working on the pump, or any high
pressure part of the installation. Service should only be performed by
qualified personnel.
•The high pressure water, 4,136 bar (60,000 psi) in waterjet cutting systems
should not be a cause for concern. Users must have due respect for these
pressures and use proper SAFETY PROCEDURES and SAFE WORK HABITS.
•Everyone associated with the waterjet cutting system must realize that the
force of the waterjet cutting stream can penetrate many dense or strong
materials.
•Keep all untrained people away from the waterjet cutting area. Use barriers
or partitions if needed.
•Safety glasses must be worn at all times in the waterjet cutting area.
•All EMERGENCY STOP buttons must be checked periodically. The normal
operating position is pulled out.
•To check: turn on power and activate the EMERGENCY STOP buttons by
pushing them in to see if the power goes off. Each device should be checked
on a specified schedule. Each time the device is checked, it must function or
be replaced before operating the system.
•Apply High Purity Goop (P/N 10084440) to all threaded high pressure
connections. All tubing, fittings and bolted connections should be torqued to
recommended values. Do NOT attempt to tighten or loosen a HP water fitting
when the circuit is pressurized, see High Pressure (HP) Piping Safety.
•All high pressure leaks must be repaired immediately.
•Inspect all equipment on a scheduled basis.
•Before performing any maintenance on the unit, MECHANICALLY LOCK
THE MAIN CONTROL POWER OFF, and assure the high pressure has been
bled off.
•If steam or fog is noticed inside the clear top cover, this indicates a high
pressure leak. Turn off intensifier and bleed pressure before lifting the cover.
•Pressing the emergency stop button turns off the control power to the
intensifier, stops the intensifier pump, and bleeds high pressure water
through the dump valve. Depressurization of the high pressure system can
be heard when the dump valve opens as a loud hissing that fades quickly as
the pressure drops.

SECTION 1
INTRODUCTION
Page 1-10 49831878
Never do any work on the unit without making sure the
electrical panel disconnect is locked out with a padlock in
the OFF position.
Never work on any high pressure component, or loosen any
high pressure fittings without first bleeding the system and
assuring there is no high pressure water present.
Make sure the safety devices are operational. To panic stop
the pump and bleed the high pressure, the EMERGENCY
STOP buttons must be pushed in. The system pressure
dump valves must be open.
Do not attempt to touch or be exposed to high pressure
water. The high pressure water will penetrate all parts of
human body without exception.
The liquid stream or material ejected by these extreme
pressures can injure or kill.
Do not operate the intensifier with any of the covers opened
or removed.

1.4.3 High Pressure (HP) Piping Safety
High pressure piping must be installed without torsional or bending stresses.
Proper supports and guides must be provided. 9/16” outside diameter HP
tubing and fittings are recommended between the pump and the cutting
station. This large tubing size will reduce vibration, strain and motion between
the pump piping and the cutting area. The larger piping diameter also reduces
pressure drop, and pressure pulsation.
Do not try to repair a leak in a HP water fitting when it is
pressurized. Always shut off the power and bleed the HP
water before doing maintenance on HP components. Weep
holes are provided to release HP water if leakage occurs at a
sealing surface. If a fitting is loosened with HP water
present, a jet of HP water will exit the nearest weep hole
with possible hazardous results.
Use extreme caution when handling high pressure
equipment. Possible failure from fatigue cracking or over-
pressurization can result in a hazardous high pressure
leak, or component failure.
A flexible ¼” HP tube (whip) is frequently used on the
cutting system to allow cutting nozzle movement. Supports
and guides for the whip must be used, anti-vibration
fittings and proper support must be provided to prevent
failures from external loads (non-water related stresses).
When tightening or loosening HP connections, always use a
supporting wrench to avoid bending forces or stress on the
connection. Do not exceed recommended torque values
High pressure piping and fittings designed to 4,100 bar
(60,000 psi) must always be used. Failure to do so may lead
to catastrophic component failure, which can cause
equipment damage, injury or even death.

listed in Section 11 “Specifications”. Operation without proper water quality
will shorten the life of certain intensifier parts and void their warranty.
Use only plastic or copper plumbing from the cutting water source to the SL-IV
PLUS pump cutting water supply filter.
Thoroughly purge the cutting water supply plumbing prior to connecting to the
SL-IV+ pump to avoid construction residue contaminating the pump.
HP Water OUT:
Properly rated, sized, and supported high pressure (HP) piping must be used to
transport the high-pressure water from the SL-IV+ pump to the point of use.
If new HP discharge piping is installed, all burrs that might come loose under
high pressure must be carefully removed, and the tubing sections purged with
compressed air prior to assembly. Further, it is strongly recommended that the
HP piping be purged under high pressure operating conditions, using a large,
cheap orifice. Contamination from the HP piping will be released when the
tubing expands under pressure. If the HP piping is not purged, expect to have
early HP valve and orifice failures.
All stainless steel parts should have High Purity Goop (P/N 10084440) applied
to the threads and contact surfaces prior to assembly. Do NOT USE ANY
OTHER ANTI-SEIZE COMPOUND. Failure to use High Purity Goop will result
