Control Wiring:
Wiring for remote control of the pump must be in accordance with national and
local electrical codes. The SL-IV+ Waterjet Pump has a 24vdc electrical control
system and has a connector port for remote operation wiring on the pump
control enclosure.
2.6 Service Connections
Cooling Water IN/OUT:
Supply plumbing must be properly sized to handle the necessary flow and
pressure. Piping must meet national and local piping codes.
If municipal or well water is used for cooling, insure that the supply will flow a
minimum of 3 gallons per minute at a minimum of 30 PSIG under maximum
usage conditions.
If a facility-wide chilled water (active or evaporative tower) system is used for
cooling, insure that there is a minimum of 30 PSIG pressure differential
between the facility supply and the return (discharge) plumbing. Installation of
an in-line pressure boosting pump may be necessary to provide adequate
cooling flow.
Cutting Water IN:
Supply piping must be properly sized to handle the necessary flow and
pressure, and must be capable of providing a minimum of 30 psi at maximum
flow demand to insure adequate supply to the intensifier. Piping must meet
national and local piping codes.
Prior to operation, insure that the cutting water meets minimum standards
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
