Component Identification
Every Lube Master pump package includes a pump
assembly and a reservoir.
Reservoir - Oil or Grease
• Container for holding oil or grease.
• Grease models include a follower plate.
• The reservoir mounts directly to the Lube Master
pump.
Oil Reservoir
• The oil reservoir has a fill cap (30) and screen (31),
located on top (FIG. 2).
Grease Reservoir
• The grease reservoir requires an external air-free
supply source connected to the fill stud (13).
Pump Assembly
• The pump assembly can be driven by an electric
motor or by a rotating or oscillating machine motion.
• The pump assembly must always be installed with
the reservoir (11) in a vertical position to ensure
proper operation.
• Always use lock washers with mounting bolts and
make certain that the bolts are properly torqued.
Motor and Drive Options
Gear Reducer
Gear reducers have either a 10:1 or 60:1 reduction or an
oscillating clutch drive that can be activated by a
machine motion.
Low-Level Switch (Optional)
A Low-level switch provides a signal when the lubricant
level in the reservoir is low.
FIG. 2: Oil Reservoir
FIG. 3: Grease Reservoir

To avoid injury from any rotating parts, all of the
exposed drive shafts must be guarded.
NOTICE
Gear reducer units are shipped without lubricant.
Before operating, always check lubricant level and fill
per manufacturers instructions. Operation without lubri-
cant will damage the gear reducer. A table of sug-
gested lubricants is provided on page 23.

Installation
83A2781B
Installation
The reference letters and numbers used in the following
sections, refer to FIG. 1.
Components are completely assembled when the Lube
Master pump package is received from the factory.
Reassembly instructions for these components are pro-
vided in Maintenance and Repair, beginning on page
16.
Grounding
Install a 12 gauge (1.5 mm) minimum ground wire
between the Lube Master pump package and a true
earth ground.
Pressure Relief Valve
Pressure Relief Valve
• The pressure relief valve must be rated for no more
than the working pressure of any component
installed in the system.
• Install a pressure relief valve close to every pump
assembly outlet and before any auxiliary fitting.
Choose an Installation Location
• Select a location that will adequately support
the weight of the pump package and lubricant,
as well as all plumbing and electrical connec-
tions.
• Refer to the mounting hole layouts provided in
Dimensions, beginning on page 34. No other
installation configuration should be used.
• Use only the designated mounting holes and
provided configurations.
• Use fasteners that are strong enough to support
the weight of the pump package and lubricant
when securing the pump package to the mount-
ing surface.
Pump Package Installation
Procedure
1. Secure the pump package with user supplied
attaching hardware to the installation location. All
fasteners should be tightened to the proper torque.
2. Install all guards and mechanical linkages or con-
nections.
3. Connect the power source to the pump package
drive.
4. Fill with lubricant. See Fill the Reservoir, beginning
on page 9.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
To prevent over-pressurization, which can result in
serious injury from splashing fluids due to equipment
rupture, a pressure relief valve must be installed
close to every pump assembly outlet to alleviate
unintended pressure rises in the system and protect
the pump assembly from damage.
AUTOMATIC SYSTEM ACTIVATION HAZARD
If the system is equipped with an automatic timer that
activates the pump lubrication system, unexpected
activation of the system could occur. This could result
in serious injury, including skin injection and amputa-
tion from moving parts.
Before installation or removal of the pump package
from the system, disconnect power and relieve pres-
sure.

Setup
3A2781B 9
Setup
Fill the Reservoir
Material Cleanliness
The lubricant used to fill the system must be clean. If
there is doubt about cleanliness, the lubricant should be
filtered before using in the system. System life and con-
sistent operation will both be improved by using clean
lubricant.
After filtering the lubricant, protect the lubricant supply
from debris.
On all pump packages, the lube piston diameter is very
close to the diameter of the chamber in the pump body.
Contaminants in the lubricant could cause scoring,
resulting in erratic pump operation and costly parts
replacement.
Temperature Effects
Flow characteristics of the lubricant may change due to
drastic temperature changes. Choose a lubricant that
flows properly at all temperatures expected in the sys-
tem environment.
Overhead Supply Adapter Assemblies Only
The recommended inlet pressure is 15 psi (0.103 MPa,
1.03 bar) or less.
Fill Oil Reservoir Model
The reservoir on oil models has a fill cap (30) and filter
screen (31).
1. Clean the area around the fill cup to avoid contami-
nation during filling.
2. Open the fill cap (30) and slowly pour oil into the
reservoir (11) through the filter screen (31).
NOTE: The filter screen (31) removes any large par-
ticles present in the oil.
3. When filling is complete, close the fill cap (30) and
clean up any spillage.

Fill Grease Reservoir Model
• Filling the grease reservoir requires an external,
air-free supply source connected to the fill stud (13).
• Avoid introducing air into the system, by keeping
enough grease in the supply source to fill the reser-
voir without being disconnected.
• Operate the supply source at a steady speed to
allow air-free filling of the reservoir. Filling the
reservoir too fast may result in air pockets.
• Visually check the level of grease.
- For reservoirs with plastic cylinders, the grease
level can be viewed through the cylinder.
1. Remove the fill cap (12)
2. Connect the grease supply source to the fill stud
(13).
3. Loosen the drain plug (E), located on the opposite
side of the base from the fill stud (13) (FIG. 6).
4. Begin to slowly fill the reservoir, allowing for air
trapped under the follower to exhaust out the open
drain plug.
5. After grease that is free of air flows from the drain,
tighten the plug (E) and continue to fill the reservoir
until follower is at the vent hole in reservoir tube
(any remaining air and small amount of grease will
exit drain).
6. When filling is complete, turn off the supply source
and disconnect it from the fill stud (13). Replace the
cover (12).
NOTE: Integrating a check valve inside of the fill
stud prevents lubricant from being forced back out.
7. Loosen the pump assembly outlet fitting.
8. Operate the pump until lubricant that is free of air
flows from the outlet port.
9. Tighten the mainline connection at the pump. The
pump is now free of air.
NOTE: If the pump will not take a prime, inject sev-
eral ounces of heavy oil through the fill stud. The
pump primes on the oil pulling the grease behind it.
If this method is used, all injected oil should be dis-
charged at the loosened system mainline connec-
tion, in addition to any air.
OVER PRESSURIZATION HAZARD
Over pressurization can result in serious injury from
splashing fluids due to equipment rupture. Fill slowly
to avoid over pressurizing the reservoir.
