1.3 DESCRIPTION
1.3.1 All Tri-Lube Pump Packages consist of the following
components:
A reservoir for holding the lubricant. Reservoirs are a.
cylindrical in shape and are made from transparent
plastic or metal depending on the specific model.
Each reservoir is equipped with a low level switch
activated by the follower assembly and a rotating
paddle to assist priming of the pump.
A pump element is available with either a fixed or b.
adjustable output. All pump elements are equipped
with an adjustable relief valve that relieves to
atmosphere. A second or third pump element can be
added in the field to supply additional output volume
or additional lube points where required.
A gearmotor (12 or 24 VDC) or a motor and gear c.
reducer (115 or 230 VAC, 1 ph, or 230/460 VAC, 3
ph) which drives the pump.
A pump body which houses the pump drive d.
eccentric and to which all other components are
attached.
1.4 OPERATION
1.4.1 Figure 1-1 shows the general relationship of the pump
element and the drive eccentric. The following steps
outline the operating sequence:
Grease in the reservoir keeps the pump body full a.
during normal operation and maintains a head
pressure to accomplish two objectives.
Provide constant lubrication to the moving •
pump components.
Supply lubricant to the piston chamber in the •
pump cylinder.
A rotating cam (Item 1) forces the pump piston b.
(Item 2) forward displacing lubricant from the pump
cylinder, past an internal discharge check valve and
out of the pump outlet.
As the cam (Item 1) continues to rotate, the pull-c.
back ring (Item 3) pulls the pump piston (Item
2) back to the prime position allowing grease to
re-prime the piston chamber for the next stroke.
Also attached to the eccentric shaft is a paddle (not
shown) with an angled surface that forces grease
into the pump chamber as it rotates and also aids
in dispersing any small air pockets that might be
present in the grease.

2.1 MOUNTING THE PUMP
2.1.1 The pump should be mounted in a vertical position with
the reservoir at the top and in a protected location, but
where it is accessible for filling and routine maintenance.
DC Motor, Front View
DC Motor, Side View
2.1.2 The pump is mounted using two 5/16” or two 8 mm
bolts (furnished by user) that pass through the mounting
feet on the pump body. The mounting bolt length will
depend on the thickness of the mounting surface
and whether the holes are to be tapped for the bolts or
locked in place with nuts and washers. Mounting
dimensions are shown in Figure 2-1
2.2 WIRING THE PUMP
2.2.1 Electrical connections are shown in Figure 2-2
2.2.2 Wiring to the AC motors should be 16 AWG stranded
wire with insulation rated for 300 V max and 105ºC.
2.2.3 The DC pump motors and all low level switches may be
wired with 18 AWG stranded wire cable.

2.3 FILLING THE RESERVOIR
2.3.1 The reservoir should be filled with clean air
free grease of the type recommended by the machine
builder and having an NLGI grade number consistent with
the ambient operating temperature of the equipment
(grease must be pumpable at the lowest anticipated
operating temperature).
CAUTION
Do not fill the reservoir with grease heavier than
NLGI #2. For temperatures below -5OF (-20OC), use
NLGI #1 or lighter grease.
2.3.2 Filling is accomplished by connecting a suitable transfer
pump to the fill fitting in the front of the pump housing
(See Figure 2-3). Before connecting the transfer pump,
make sure that both the lube fitting and the coupler are
clean and that the hose and transfer pump are full of
clean grease that is free of air.
2.3.4 For subsequent re-filling, unless the reservoir
has been allowed to run dry or air was pumped
into the reservoir, it will not be necessary to
remove the yellow plug or fill above the vent hole.
2.4 PURGING THE PUMP AND SYSTEM
OF AIR
2.4.1 Operate the pump with the main line
disconnected until grease free of air is seen at
the pump outlet.
2.4.2 Fill and purge system lines and divider valves
following the procedures outlined in Trabon
Bulletin L30103.
2.4.3 Once all lines and dividers have been purged free
of air, reconnect pump to mainline.

2.3.3 For the initial filling, or if the reservoir has been allowed
to run dry, removing one of the pump position yellow
plugs from the pump body will facilitate expelling air
from the body and reservoir. Slowly start to fill the
reservoir until grease free of air flows from the open
pump position. At this point, stop the transfer pump and
re-install the yellow plug. After the plug is installed, fill
slowly until the follower seal is slightly above the vent
hole in the reservoir tube. This will allow air remaining
below the follower to escape. When grease free of air is
seen at the vent, stop filling.

2.5 ADDING PUMP ELEMENTS
CAUTION
To avoid personal injury or severe internal damage to
the drive-train, or pump element, these procedures
must be followed carefully.
2.5.1 Disconnect power to the pump motor.
2.5.2 Remove sealing plug 1 (figure 2-4a).
2.5.3 Pull out pump piston 2 until it extends approximately
1-1/8” (29 mm) from end of cylinder to end of mushroom
head.
2.5.4 Insert element into housing at approximately a 15 degree
angle as shown in figure 2-4b.
NOTE: If pump is full of grease, it will be necessary
to clear a path through the grease using a clean
screwdriver.
2.5.5 Rotate element down (figure 2-4c) engaging mushroom
head between cam 3 and retracting ring 4.
2.5.6 Tighten element 18-22 fl-lbs (25-30 N-m). Do not over
torque as housing threads will be stripped.
2.6 PUMP ADJUSTMENTS
2.6.1 Adjusting the Relief Valve. Each pumping element
incorporates an adjustable relief valve to protect the
system against overpressure. The relief setting can be
adjusted by loosening the locking nut (1) (See Figure
2-5) and turning the cap clockwise to increase the relief
pressure, and counterclockwise to decrease the relief
pressure, as required by the system application.
CAUTION
Do not adjust above 2900 psi (200 bar) for DC pumps
or 5075 psi (350 bar) for AC pumps as pump or motor
damage may result.
2.6.2 Pump Output Adjustment. The nominal delivery
rate of the pumping element can be adjusted by
loosening the locking nut (1) (See Figure 2-6) and
rotating the adjustment screw (2)clockwise to reduce
delivery, or counterclockwise to increase delivery
of the lubricant. The output adjustment table describes
the equivalent outputs that can be obtained by varying
the distance “A” of the adjustment screw. (See Table 1)
2.5.7 Fill reservoir with clean grease (See Section 2-3) and run
pump for 1 minute to check for grease output. If none is
seen, it could indicate that the element was not properly
installed.

5.1 PUMP DOES NOT PRODUCE FLOW
5.1.1 Make sure that reservoir contains an adequate
supply of air free grease that is pumpable at the
operating temperature being encountered.
If reservoir is empty, refill following the instructions a.
in section 2.3 and purge pump free of air.
If grease is too heavy for the temperature conditions, b.
empty reservoir and refill with grease of the correct
NLGI grade number (refer to section 2.3).
If grease contains air pockets and pump is air c.
bound, empty reservoir and refill with grease that is
free of air (refer to section 2.3).
5.1.2 On adjustable pumps, make sure the output adjustment
is not set to minimum (refer to section 2.6.2).
5.1.3 Make sure that power of correct voltage is being supplied
to motor and that motor is operating.
If power is not present, check fuses and wiring and a.
correct any problems found (refer to section 2-2).
If power is present and motor does not operate, a.
remove pump element (Refer to section 2-5) and
check for motor operation.
5.2 LOW LEVEL SWITCH DOES NOT SIGNAL
LOW LEVEL
5.2.1 Make sure that level switch is properly wired (see figure
3-1) and correct any problems found.
5.2.2 Make sure that the follower tracks the drop in grease
level to the bottom of the reservoir.
If follower appears stuck in reservoir at mid travel, a.
there is most likely a pocket of air between the
bottom of the follower and the top of the grease
column. Purge air pocket by filling reservoir until
follower is just above vent hole in reservoir side
wall and grease free of air is seen at vent (refer to
section 2.3).
If follower tracks fall of grease level and switch does a.
not signal, replace Level/Switch/Cover/Follower
assembly (refer to section 3.1).
5-1
If motor still does not operate, replace motor (refer a.
to section 3-4 and 3-5).
If motor operates, check for bent or binding a.
components (pump piston and cylinder, cam and
retract ring or gear reducer). Replace any damaged
components (refer to sections 3.3, 3.4 and 3.5).
