Graco G3 - Set Pump Outlet Volume; Load Pump with Grease

Setup
20 332291P
Set Pump Outlet Volume
NOTE:
• 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. Follow the Pressure Relief Procedure, page 19,
before making any adjustments to the pump
volume.
2. Use a wrench to turn the pump element counter-
clockwise to loosen. Do not remove the entire
pump element. Only back the pump element out
enough to allow a spacer to be slid on or off. (F
IG.
18).
3. If needed, remove or insert spacers to achieve the
required pump output volume. A tool may be
needed to facilitate removal.
The pump volume control is set using no spacers,
one (1) or two (2) spacers (F
IG. 18).
Do not use more than two (2) spacers to adjust the
output volume.
4. Tighten the pump element fitting. Torque fitting to
50 in. lbs. (5.6 N•m).
• The amount of dispensed volume varies depending
upon external conditions, such as lubricant
temperature and back pressure from downstream
connections.
• 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 needed to ensure the desired
lubrication 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
temperature. Consult with the machine and lube
manufacturer for details.
• The reservoir can be filled using a hand operated
pump, a pneumatic pump, or an electric transfer
pump.
• Do not overfill the reservoir.
• Do not operate the G3 pump without a reservoir
attached.

NOTICE
• Always clean the fitting (D) (F
IG. 19) with a clean
dry cloth prior to filling the reservoir. Dirt and/or
debris can damage the pump and/or the lubrica-
tion system.
• When changing greases, always use compatible
fluids or greases.
• Use care when filling the reservoir with a pneu-
matic or an electric transfer pump, to not pressur-
ize and break the reservoir.
