Graco 332291C Manual De Usuario

NOTE: 

•

Before making any adjustments to pump volume, 
Relieve Pressure following procedure on page 18.

•

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. 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

. 13). 

Do not use more than 2 spacers to adjust output vol-
ume. 

•

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).

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

. 15).

•

Do not operate G3 without reservoir attached.

• Always clean fitting (D) with a clean dry cloth 

prior to filling reservoir. Dirt and/or debris can 
damage pump and/or lubrication system.

• Care must be used when filling the reservoir 

using a pneumatic or electric transfer pump to 
not pressurize and break the reservoir.
