WARNING
A red-handled bleed-type master air valve (11h)
and a fluid drain valve (208) are supplied. These
components help reduce the risk of serious injury,
including splashing of fluid in the eyes or on the
skin, and injury from moving parts if you are adjust-
ing 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.
DThe red-handled bleed-type master air valve
(11h) 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 pump air
filter/regulator (11a).
DThe pump air filter/regulator (11a) controls pump
speed and outlet pressure by adjusting the air
pressure to the pump. It includes an air filter with a
40 micron polypropylene element, to remove harm-
ful dirt and moisture from the compressed air
supply. Locate close to the pump, but upstream
from the bleed-type master air valve (11h).
DThe air line lubricator (11b) provides automatic
lubrication of the air motor.
DThe air relief valve (11j) opens automatically to
prevent overpressurization of the pump.
DFluid is supplied to the pump through the suction
hose (16) and tube (109). The suction tube (109)
is installed in the shaft of the agitator (102). See
Fig. 1.
DThe fluid filter (206) includes a 60 mesh (250
micron) stainless steel element to filter particles
from the fluid as it leaves the pump.
DThe fluid drain valve (208), is mounted in the
bottom of the fluid filter bowl, and is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING at left).
DThe back pressure regulator (12) controls back
pressure to the gun and maintains proper circula-
tion pressure.
DThe back-geared agitator (102) keeps the fluid in
suspension and also includes a suction tube (109)
to draw fluid from a 55 gallon drum.
DThe air-operated elevator (150) allows you to
raise the drum cover and agitator from an empty
drum, replace the drum, and lower the agitator into
the new drum.
