System Accessories (continued)

WARNING

A bleed-type master air valve (E) and a fluid drain
valve (M) are required in your system. These
accessories 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 repairing the pump.

The bleed-type master air valve 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.
Order Part No. 107141.

The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Order Part No. 235992.

Air Line Accessories

Install the following accessories in the locations shown
in Fig. 2, using adapters as necessary:

D

An

 

air line lubricator (D)

 provides automatic air

motor lubrication.

D

A

 

bleed-type master air valve (E)

 is required in

your system to relieve air trapped between it and
the air motor when the valve is closed (see the

WARNING

 above). Be sure the bleed valve is eas-

ily accessible from the pump, and is located

downstream

 from the air regulator.

D

An

 

air regulator (F)

 controls pump speed and out-

let 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.

D

A

 

pump runaway valve (C

) senses when the

pump is running too fast and automatically shuts
off the air to the motor. A pump which runs too fast
can be seriously damaged.

D

An air manifold (G)

 has a 3/4 npsm(f) swivel air

inlet. It mounts to the pump support bracket, and
provides ports for connecting lines to air-powered
accessories.

D

An

 

air line filter (J)

 removes harmful dirt and

moisture from the compressed air supply. Also,
install a 

drain valve (W)

 at the bottom of each air

line drop, to drain off moisture.

D

A second

 

bleed-type air valve (K)

 isolates the air

line accessories for servicing. Locate upstream
from all other air line accessories.

Fluid Line Accessories

Install the following accessories in the locations shown
in Fig. 2, using adapters as necessary:

D

A fluid filter (L) 

with a 60 mesh (250 micron)

stainless steel element, to filter particles from the
fluid as it leaves the pump.

D

A fluid drain valve (M),

 which is required in your

system, helps relieve fluid pressure in the hose
and gun (see the 

WARNING

 at left).

D

A gun (S)

 dispenses the fluid. The gun shown in

Fig. 2 is an airless spray gun for light to medium
viscosity fluids.

D

A gun swivel (R)

 allows freer gun movement.

D

A suction kit (T)

 allows the pump to draw fluid

from a supply container.

CAUTION

To prevent intake valve damage, always apply 

PTFE

tape to the female threads of the intake valve before
connecting a suction hose or fitting to the intake.
