Air-Powered Pumps
• Reference numbers and letters in parentheses in
the text refer to numbers and letters in the illustra-
tions.
• F
IG
. 2, page 9, shows a typical installation of an
air-powered pump. It is only a guide. Contact your
Graco distributor for actual system designs.
• Be sure all accessories, including air lines and fluid
lines, are adequately sized and pressure-rated to
meet system requirements.
• Use only electrically conductive hoses. Fluid hoses
must have spring guards on both ends.
Air Line Accessories
Install the following accessories as shown in F
IG
. 2,
using adapters as necessary.
• Bleed type master air valve (J) is required in your
system to shut off the air supply to the pump. When
closed, the valve will bleed off all air in the pump. Be
sure the valve is easily accessible from the pump.
• Air regulator (H) controls pump speed and outlet
pressure by adjusting the air pressure to the pump.
Locate the regulator close to the pump, but
upstream from the bleed-type master air valve.
• Air line filter (L) removes harmful dirt and moisture
from the compressed air supply. Also, install a drain
valve at the bottom of each air line drop, to drain off
moisture.
• Air shutoff relief valve (M) isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories.
• DataTrak: see the NXT air motor manual 311238 for
DataTrak information.
Fluid Line Accessories
Install the following accessories as shown in F
IG
. 2,
using adapters as necessary.
• Install a fluid shutoff valve at each valve drop, to
isolate the valve and fluid accessories for servicing.
• Install a fluid drain valve near the pump fluid outlet,
and at each valve station. The drain valves are
required in your system to relieve fluid pressure in
the displacement pump, hose and valve. Drain
valves at the valve stations may be mounted in the
base of a fluid regulator, using an adapter.
• Fluid regulator controls fluid pressure to the valve,
and dampens pressure surges.
• Dispense valve dispenses the fluid.
• Valve swivel allows freer valve movement.
A bleed type master air valve (J) is required to help
reduce the risk of serious injury, including fluid injection
and splashing of fluid in the eyes or on the skin, and
injury from moving parts if you are adjusting or repair-
ing the pump.
The bleed valve shuts off the air to the pump and
relieves air trapped between this valve and the pump
after the air is shut off. Trapped air can cause the pump
to cycle unexpectedly. Locate the valve close to the
pump.
