• Up to 100 or more lube points
• Use with oil or grease
• Wide range of options
• Modular design
• Option of aluminum or stainless steel injectors and manifolds
INTRODUCTION
LubriSystem™ utilized one of three (3) types of pumps: a single-
stroke air-operated pump; a multiple-stroke hand-operated
pumpr; or a continuous fl ow, electric motor pump. Fed from a
lubrican reservoir mounted above, the pump output is delivered
to oil or grease metering valves (called meters or injectors) which
distribute lubricant to bearing points. Oil or grease (NLGI #1 or
lighter) may be used with the hand-operated and air-operated
pump. Oil or NLGI #00 or ligher grease may be used with the
electic motor pump. Air-operated pumps require a solenoid-
operated air valve and controller to activate the pump. Electic
motor pumps use an electric motor (115 VAC is standard) and
a solid-state timer device to activate the pump. The injectors
are mounted in manifolds supplied by Graco. The bearing point
injectors mount at the bearing point and require no manifold.
Various accessories are available to simplify installation. An
optional pressure switch or gauge may be added at the pump
outlet port if required.
LubriSystem is referred to as a single-line, parallel system. This
means that when the solid-state timer, controller or operator
activates the pump, llubricant is forced down a single main
line to manifolds, and from there through parallel lines from
individual injectors to the lube points. If bearing point injectors
are used, no manifolds are required. Instead, the single main line
branches into parallel lines feeding the bearing point injectors. In
both cases the injectores inject lubricant to a bearing shown in
Figure 1. Once lubricant is dispensed at the lube points, system
pressure is vented by the pump. This allows the injectors to prime
themselves in preparation for the next lubrication cycle.
SYSTEM COMPONENTS
Pumps
Positive displacement, air-operated pumps are available in two
(2) pressure ratios. A manually-operated pump and an electric
motor pump are also offered. Several different types and sizes
of reservoirs allow a system to be designed precisely for your
application. Reservoirs include a fi ll stud fp reservoir refi lling.
Timer
Solid-state timer can be set to control the solenoid or motor to
initiate lube cycle at intervals of 1/2 minute to 32 hours.
Manifolds and Injectors
One manifold can distribute lubricant to as many as eight (8)
injectors. Injectors come in six (6) sizes to meet a range of lube
requirements. Bearing point injectors are fed directly from the
pump through parallel branch lines and require no manifold.
Tubing, Hardware, Fittings and Accessories
LubriSystem utilezes tough 3/16 in and 5/16 in heavywall nylon
tubing and brass fi ttings for lube points. Mounting hardware and
accessories such as reservoir low-level switches and injector
indicator assemblies are available.
FEATURES AND BENEFITS
A more effi cient method of applying lubricant, resulting in less
machine downtime, increased productivity, and a safer work
environment. In addition to these benefi ts, LubriSystem also
provides:
• Stainless steel injectors and manifolds available for corrosive
environments
• Easy system design and modifi cation
• Inexpensive components and installation
• Fast payback! In terms of savings in lube maintenance man-
hours alone, LubriSystem usually pays for itself within the
fi rst year
• Easy adjustability to meet a wide range of operating
conditions
• Quick-connect fi ll stud on pump permits complete refi ll in
minutes
• High-pressure pump can serve more points with longer
tubing runs
• Pump construction internally relieves system pressure,
requiring no extra cost in external valving
• Several reservoir sizes available to fi t a variety of
applications
• Visual indicator pin available fo system diagnostics
