Installation
(AIR-POWERED PUMPS)
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.
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.
Air and Fluid Hoses
Be sure all air hoses (H) and fluid hoses (N) are prop-
erly sized and pressure-rated for your system. Use
only electrically conductive hoses. Fluid hoses must
have spring guards on both ends.
Mounting Accessories
WARNING
For Model 222940 Premier Pump, do not lift the
pump by the lift ring when the total weight exceeds
550 lb (250 kg).
Mount the pump (A) to suit the type of installation
planned. Fig. 3 on page 8 illustrates a ram-mounted
pump in a multi-gun header system. Pump dimensions
and the mounting hole layout are shown on pages 36
and 37.
If you are mounting the pump on a ram, refer to the
separate ram manual for installation and operation
instructions.
Air Line Accessories
Install the following accessories in the order shown in
Fig. 3, using adapters as necessary:
An air line lubricator (D) provides automatic air
motor lubrication.
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
easily accessible from the pump, and is located
downstream from the air regulator.
An air regulator (F) 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.
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.
An air manifold (G) has a swivel air inlet. It
mounts to a ram, and has ports for connecting lines
to air accessories, such as the
ram air regulator
(T).
An air line filter (J) removes harmful dirt and
moisture from the compressed air supply.
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 positions shown
in Fig. 3, using adapters as necessary:
Install a fluid shutoff valve (P) at each gun drop,
to isolate the gun and fluid accessories for servic-
ing.
Install a fluid drain valve (M) near the pump fluid
outlet, and at each gun station. The drain valves
are required in your system to relieve fluid pressure
in the displacement pump, hose and gun (see the
WARNING at left). Drain valves at the gun stations
may be mounted in the base of a fluid regulator
(L), using an adapter.
A fluid regulator (L) controls fluid pressure to the
gun/valve, and dampens pressure surges.
A gun or valve (S) dispenses the fluid. The gun
shown in Fig. 3 is a high pressure dispensing gun
for highly viscous fluids.
A gun swivel (R) allows freer gun movement.
