Installation
ASSEMBLE THE PUMP
Assemble the displacement pump (105) to the air
motor (101) as instructed on pages 12–13.
SYSTEM ACCESSORIES
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. 112730.
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. 224774.
Air and Fluid Hoses
Be sure all air hoses (H) and fluid hoses (N and P) are
properly sized and pressure-rated for your system.
Use only electrically conductive hoses. Fluid hoses
must have spring guards on both ends. Use a whip
hose (P) and a swivel (R) between the main fluid hose
(N) and the gun (S) to allow freer gun movement.
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. Fig. 2 illustrates a cart-mounted system.
Pump dimensions and the mounting hole layout are
shown on page 23.
If you are using a floor stand, refer to its separate
manual for installation and operation instructions.
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
at left). Be sure the bleed valve is easi-
ly accessible from the pump, and is located
down-
stream
from the air regulator. Order Part No.
112730.
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 1 in. npt air inlet. It
mounts to the pump support bracket, and provides
ports for connecting lines to air-powered accesso-
ries.
D
An
air line filter (J)
removes harmful dirt and
moisture from the compressed air supply.
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. It includes a
fluid
drain valve (M),
which is required in your system
to 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 19 liter (5 gallon) pail.
