Setting Pump Outlet Volume
NOTE:
• Before making adjustments to the pump volume,
follow Pressure Relief Procedure , page 12.
• Only use Graco supplied spacers to control output
volume.
• It may be necessary to repeat this outlet volume
setup procedure after the pump is operating to
re-adjust the volume of dispensed fluids.
1. Using a wrench, turn the pump element
counter-clockwise to loosen. Do not remove the
entire pump element, only back the pump element
out enough to allow the spacer to be added or
removed (F
IG
. 9).
2. If needed, remove or insert spacers to achieve
required pump output volume. A tool may be
needed to facilitate removal.
Pump volume control is set using either no (0)
spacers, one (1) spacer, or two (2) spacers (F
IG
. 9).
Do not use more than two (2) spacers to adjust out -
put volume.
3. Tighten the pump element fitting. Torque fitting to
50 in-lb (5.6 N•m).
• The amount of dispensed volume varies depending
upon external conditions such as lubricant tem -
perature and back pressure from downstream con -
nections.
• Use of these volume adjustments in conjunction
with setting the ON time of the pump allows for
control of the output volume.
• Use these volume adjustments as a starting point
and adjust, as necessary, to ensure desired lubrica -
tion dispense.
Load Pump with Grease
To ensure optimal performance from the G3 pump:
• Only use NLGI #000 - #2 greases appropriate for
the application, automatic dispensing, and the tem -
perature. Consult with machine and lube manufac -
turer for details.
• The reservoir can be filled using a hand operated
pump, pneumatic pump or electric transfer pump.
• Do not overfill.
• Do not operate the G3 pump without reservoir
attached.
1. Connect the fill hose to the inlet fitting.
2. For higher viscosity fluids, start pump to rotate stir -
ring paddle during fill to prevent air pockets from
forming. Do not exceed 30 minutes run time.
For models using an external controller, start pump
operation per your controller specifications.
3. For the initial run, fill the pump with grease. After all
of the air under the follower plate flows out through
the nylon line, remove the nylon line along the
transparent reservoir.
NOTE : Pull the nylon line as shown in F
IG
. 10 to avoid
pulling the vent port off of the pump.

NOTICE
• Always clean inlet fitting with a clean dry cloth
prior to filling reservoir. Dirt and debris can
damage pump and lubrication system.
• Care must be used when filling the reservoir
using a pneumatic or electric transfer pump to
not pressurize and break the reservoir.
