Setting Pump Outlet Volume
NOTE:
•
Before making any adjustments to pump volume,
Relieve Pressure
following procedure on page 21.
•
Only use Graco supplied spacers to control output
volume.
1.
Use a wrench to turn pump element counter-clock-
wise to loosen. Do not remove entire pump element.
Only back pump element out enough to allow
spacer to be slid on or off.
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) spac-
ers, 1 or 2 spacers (F
IG
. 20).
Do not use more than 2 spacers to adjust output vol-
ume.
NOTE:
•
The amount of dispensed volume can vary depend-
ing on external conditions such as lubricant tem-
perature and back pressure from downstream
connections.
•
Use of these volume adjustment in conjunction with
setting the ON time of the pump will allow for control
of the output volume.
•
Use these volume adjustments as a starting point
and adjust as necessary to ensure desired lubrica-
tion dispense.
3.
Tighten pump element fitting. Torque fitting to 50 in.
lbs (5.6 N•m).
Loading Grease
To ensure optimal performance from the G3:
•
Only use NLGI #000 - #2 greases appropriate for
your application, automatic dispensing, and the
equipment’s operating temperature. Consult with
machine and lube manufacturer for details.
•
The reservoir can be filled using a hand operated
pump, pneumatic pump or electric transfer pump.
•
Do not overfill (F
IG
. 23).
•
Do not operate G3 without reservoir attached.
