Installation
8 3A1334P
Stationary Mounting Layout
Plan the layout for easy operator access to the pump air
controls, sufficient room to change drums and a secure
platform.
Pump Mounting
1. Install bung adapter (K) into bung mount/bracket/or
drum cover.
2. Install pump (B) into bung adapter (K).
Installing Outlet Hose (F
IG
. 3)
1. Connect the swivel adapter (aa) to the pump fluid
outlet. Tighten securely and torque as recom-
mended below:
• For NPT models: 1 to 1-1/2 turns past hand
tight.
• For BSPT models: 1-1/2 to 2 turns past hand
tight.
2. Connect fluid hose (A) to the swivel adapter (aa).
3. Connect a suitable dispensing valve or extra hose to
the 6-ft hose.
Air Line and Accessories
NOTE: Install the air line accessories in the order shown
in the Typical Installation on page 6.
• Use thread sealant on all male threads
except
swivel connections.
• Install a pump runaway valve (D) to shut off the air
to the pump if the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can
be seriously damaged.
• Install the air regulator (G) to control pump speed
and pressure.
For NPT models order Graco Part No. 24H420 or for
BSP models order Graco Part No. 24H419.
• Install a bleed-type master air valve (F) upstream
from the pump air regulator (G) but within easy
reach of the pump.
For NPT models order Graco Part No. 110223 or for
BSP models order Graco Part No. 125272.
• On the main air supply line from the compressor,
install an air line filter (H) to remove harmful dirt and
contaminants from the compressor air supply.
Follow Plate - Grease Models Only
For grease models only a follow plate is required for
pumping fluid from the drum. See page 11 for follow
plate installation instructions.
The maximum working pressure of each pump in
your system may not be the same. To reduce the risk
of over-pressurizing any part of your system, which
may result in component rupture, fire or explosion
and cause serious bodily injury, be sure you know
the maximum working pressure rating of each pump
and its connected components.
• Never exceed the maximum working pressure of
the lowest rated component connected to a partic-
ular pump.
• Be sure you know the maximum working pressure
of each component.
• Do not exceed the maximum pump cycle rate.
• Regulate air pressure to prevent over pressuriza-
tion at fluid section of the pump.
• Regulate air pressure to the pump so that no fluid
line component or accessory is over pressurized.

NOTICE
Do not hang the air accessories directly on the air
inlet. Mount them on brackets. Always use a flexible
hose between all connections. The air inlet is not
strong enough to support accessories and may cause
one or more to break.
