Rev.20170601 V1.0E HPC INSTALLATION & OPERATION MANUAL 5
SYSTEM PRECAUTIONS:
Safety Valve:
HPC Systems generate pressure by positive displacement. A Bypass Pressure Regulating Valve is
provided as a safety valve and to control the maximum system pressure and to prevent over pressurization.
Incorrectly adjusting the regulator setting may void warranty and could result in personal injury or damage to the
pump or your machine tool.
Do not remove Pressure Regulating Valve from system.
The Manufacturer does not assume any liability or responsibility for the misuse of a customer's high-pressure
system.
Pump Lubrication:
Change oil after first 50-100 hours of operation and every 500 hours thereafter. Fill crankcase
with approximately 25 liters (845 oz) with approved oil. Refer to the Preventative Maintenance section for a list of
approved oils.
DO NOT RUN PUMP WITHOUT OIL IN THE CRANKCASE.
Inlet Pressure:
A positive head pressure must be maintained to avoid problems associated with cavitation. In so
doing, a dedicated supply pump is required to feed coolant to the HPC inlet. The supply pump's pressure capability
should be determined prior to its installation. The HPC filter vessels have a pressure rating of 4.1 Bars(60psi)
maximum. For supply pumps that provide excessive inlet pressure, regulating 4.1 Bar(60psi) maximum is required.
The accumulation of fine particulate in the active filter will create a pressure drop in the coolant supply through
the filter.
Filtration:
High capacity filter bag elements rated at 100, 50, 25, 10 or 5-micron are available from our factory.
Coolant Viscosity:
The standard HPC may be used to pump coolants or oils of viscosity down to 125
SUS(cST:26).
Considerations before Installation
A. Before Installing the HPC Unit, verify that your entire coolant delivery system(hoses, valves fittings,
coolant couplings ) is capable of supporting your desired operating pressure.
B. For best results, replace contaminated coolant and clean out machine reservoir to remove accumulated chips
and debris.
C. Your HPC Unit uses both tapered pipe (PT/NPT) fittings and 37°JIC hydraulic fittings. The JIC fittings
are designed to seal against pressure and vacuum leaks without the use of any pipe sealant compound.
For threaded PT/NPT connections, use curing pipe thread sealant(such as Loctite #565) or PTFE liquid/tape.
If tape is used, do not wrap beyond the last thread to avoid tape from being lodged within the system.
D.

Section Ⅲ - Installation Guidelines
LOCATING THE PUMPING SYSTEM
・
The HPC Unit should be located to minimize the required hose lengths between the HPC and your
machine.
Verify HPC interface cable length is adequate to reach machine tool.
・
Position the pump assembly to provide adequate work space and allow room for checking the oil level,
changing oil, inspecting pressure gauges, and servicing filters.
・
If possible, install a completely submerged baffle plate in the coolant tank to separate the supply pump inlet
point from the coolant returning to the tank. This helps reduce aeration and turbulence in the coolant supply to
the HPC.
