information.

SAFETY W ARNINGS
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the equipment or accessories, such as overpres -
surizing, modifying parts, using incompatible chemicals and flu -
ids,
or using worn or damaged parts, can cause them to rupture
and result in serious bodily injury , including eye injury , fire, ex -
plosion
or property damage.
NEVER alter or modify any part of this equipment; doing so
could
cause it to malfunction.
CHECK all equipment regularly and repair or replace worn or
damaged
parts immediately .
Take precautions to avoid a toxic fluid spill. See USING HAZ-
ARDOUS FLUIDS
, below .
System Pressure
This pump develops 100 psi (7 bar) MAXIMUM FLUID WORK -
ING
PRESSURE at 100 psi (7 bar) maximum incoming air pres -
sure. Never exceed these maximum pressures, or the maxi-
mum working pressure of the lowest rated component in your
system.
Fluid Compatibility
BE SURE all fluids and solvents used are chemically compat-
ible with the “Wetted Parts” and “Non–wetted Parts” (refer to
TECHNICAL
DA TA on pages 31–35). Always read the fluid and
solvent manufacturer ’s literature before using them in this
pump.
Diaphragm failure will cause non–wetted parts to be exposed
to fluid. This fluid will be exhausted with the air through the
muffler. When pumping acids, flammable or hazardous fluids,
you must vent
the exhaust to a safe place, away from people,
animals, or food handling areas. Place a container at the end of
the air exhaust line to catch the fluid. See Fig 4 on page 5.
To pump acids, always use a polypropylene pump. T ake pre-
cautions
to avoid acid or acid fumes from contacting the pump
housing exterior. The acetal non–wetted parts and stainless
steel parts will be damaged by exposure to acid spills and
fumes.
NEVER use an acetal pump to pump acids.
Pressure Relief Procedure
To reduce the risk of serious bodily injury, including splashing
fluid
or solvent in the eyes or on the skin, always shut of f the air
to the pump, open the dispensing valve, if used, and open the
drain valve, to relieve all system pressure before checking, ad -
justing,
cleaning, moving, or repairing any part of the system.
USING HAZARDOUS FLUIDS
Improper handling of hazardous fluids or inhaling toxic vapors
can cause extremely serious bodily injury, even death, due to
splashing
in the eyes, ingestion, or bodily contamination. Know
what fluid you are pumping and its specific hazards. Store haz -
ardous
fluid in an appropriate, approved container . Dispose of
it according to all Local, State and Federal guidelines for haz-
ardous
fluids. Observe all the following precautions when han -
dling
known or potentially hazardous fluids.
1. Always wear appropriate clothing and equipment, such as
eye protection and breathing apparatus, to protect your-
self.
2. Pipe
and dispose of the exhaust air safely . If the diaphragm
fails, the fluid is exhausted along with the air . See Fig 4 on
page 5.
3. Secure the fluid outlet hose tightly into the receiving con-
tainer
to prevent it from coming loose and improperly drain -
ing
the fluid.
4. Never move or lift a pump under pressure. If dropped, the
fluid section may rupture. Always follow the Pressure Re -
lief
Procedure above before moving or lifting the pump.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the fluid flowing through the pump
and hose. If the equipment is not properly grounded, sparking
may occur, and the system may become hazardous. Sparks
can
ignite fumes from solvents and the fluid being pumped, dust
particles and other flammable substances, whether you are
pumping
indoors or outdoors, and cause a fire or explosion, se -
rious
bodily injury , and property damage.
If you experience any static sparking or even a slight shock
while using this equipment, ST OP DISPENSING IMMEDI-
ATELY.
Do not use the system again until the cause of the prob -
lem
is identified and corrected.
Grounding
To reduce the risk of static sparking, ground the pump and all
other
equipment used or located in the pumping area. CHECK
your local electrical code for detailed grounding instructions for
your area and type of equipment. GROUND ALL OF THIS
EQUIPMENT.
1. Pump : by connecting a ground wire and clamp (see Fig 1).
2. Air and Fluid hoses : use only grounded hoses with a maxi -
mum of 500 ft. (150 m)
combined hose length to ensure
grounding continuity .
3.
Air compressor : according to manufacturer ’s recommen-
dations.
4.
All solvent pails used when flushing , according to local
code. Use only metal pails, which are conductive. Do not
place
the pail on a non–conductive surface, such as paper
or cardboard, which interrupts the grounding continuity .
5.
Fluid supply container: according to local code.

pump damage.
CAUTION
4. Reference numbers in parentheses refer to the parts
drawings and lists on pages 19–27.
Grounding
WARNING
This pump must be grounded. The steps for
grounding
may dif fer from the way you ground other
pumps. Read and carefully follow the text of FIRE
OR
EXPLOSION HAZARD on page 3 before oper -
ating
the pump.
Air Exhaust Ventilation
Be sure to read and follow the warnings and precau -
tions regarding USING HAZARDOUS FLUIDS,
and FIRE OR EXPLOSION HAZARD on page 3,
before
operating this pump.
Be sure the system is properly ventilated for your
type
of installation. Y ou must vent the exhaust to a
safe place, away from people, animals or food han -
dling
areas when pumping flammable or hazardous
fluids.
The
minimum size for the air exhaust hose is 3/8 in.
(9.5 mm) ID x 15 ft (4.57 m). If a longer hose is re -
quired, use a larger diameter hose. A void sharp
bends
or kinks in the hose.
If the diaphragm ruptures, the fluid being pumped
will
be exhausted with the air . Place a container at
the end of the air exhaust line to catch fluid in case
the diaphragm ruptures. See Fig 4 on page 5.
WARNING
Mountings
The pump exhaust air may contain contaminants.
Ventilate
to a remote area if the contaminants could
affect your fluid supply . See AIR EXHAUST VENTI -
LATION,
to the left, and Fig 4 on page 5.
CAUTION
1. The direction of the ports in the inlet and outlet mani -
folds (2) can be changed to suit your installation
needs.
A dual manifold is also available (refer to the
Typical Installations on page 6 for suggested appli-
cations). T o reposition or change manifolds, see
page
10.
2. Be sure the mounting can support the weight of the
pump,
hoses, and accessories, as well as the stress
caused during operation.
3. To mount the pump on a 55 gallon bung drum, use
Bung Kit 221–094 (see page 28). Screw the bung
adapter,
part no. 183–553, into the drum bung hole.
Screw the suction tube, part no. 183–549, into the
pump inlet manifold. Lower the pump and suction
tube through the bung adapter and into the drum.
Slide
the feet on one side of the pump securely under
the drum rim. Refer to Fig 3.
4. For all other mountings, be sure the pump is secured
with screws and nuts.
To reduce the risk of serious injury , splashing in the
eyes or on the skin, and toxic fluid spills, NEVER
move
or lift a pump under pressure. If dropped, the
fluid section may rupture. Always follow the Pres-
sure
Relief Procedure W arning on page 3 before
moving or lifting the pump.
WARNING
When Pumping High Density or Abrasive
Fluids
High density fluids prevent the lightweight and
Buna–N check valve balls from seating properly , which
reduces pump performance significantly . Conversion Kit
224–217 includes stainless steel balls for such applica-
tions
(see page 30). Refer to page 13 to change the balls.
For improved ball resistance to highly abrasive fluids
such
as those containing frit or porcelain glaze, order Ce -
ramic
Ball Kit 224–644 (see page 30).
PTFE

INSTALLATION
Air Line
A bleed–type master air valve (B) is required in your
system to relieve air trapped between this valve and
the pump after the air regulator is closed. See Fig 2.
Trapped air can cause the pump to cycle unexpect -
edly, which could result in serious bodily injury , in-
cluding splashing in the eyes, injury from moving
parts,
or contamination from hazardous fluids.
A fluid drain valve is also required. Install a drain
valve (G) close to the pump’s fluid outlet to relieve
pressure
in the hose if the hose becomes plugged.
See Fig 2. The drain valve reduces the risk of seri -
ous bodily injury , including splashing in the eyes or
on the skin, or contamination from hazardous fluids.
WARNING
1. Install the air line accessories as shown in Fig 2.
Mount these accessories on the wall or on a bracket.
Be sure the air line supplying the accessories is
grounded.
a. The
pump speed can be controlled in one of two
ways. To control it on the air side, install an air
regulator
(D). T o control pump speed on the fluid
side, install a fluid regulator (H) near the outlet.
b. Locate one bleed–type master air valve (B)
downstream
from the air regulator and use to re -
lieve
trapped air . See the WARNING , above. Lo -
cate the other master air valve upstream from all
air line accessories and use it to isolate them
during
cleaning and repair .
c. The air line filter (C) removes harmful dirt and
moisture
from the compressed air supply .
2. Install a flexible air hose between the accessories
and
the 1/4 npt(f) pump air inlet. Use a minimum 1/4”
(6.3 mm) ID air hose. Screw the air line fitting into the
air inlet and torque to 100 in–lb (1 1 N.m) maximum.
See Fig 9.
3. Do not restrict the exhaust port. Excessive exhaust
restriction
can cause erratic pump operation.
Fluid Line
1. Use grounded fluid hoses. The pump fluid outlet is
3/4
npt(f). Screw the fluid fitting into the pump outlet
and torque to 15 ft–lb (20 N.m) maximum. See Fig
9.
2. Install
a fluid regulator (H) at the pump outlet to con -
trol
pump speed, if desired. See Air Line , Step 1.a.,
for another method of controlling pump speed.
3. Install a fluid drain valve (G) near the fluid outlet. See
the WARNING to the left, and Fig 2.

INSTALLATION
Changing Manifolds
The inlet and outlet manifolds can be rotated to three po -
sitions to best suit your installation needs. The pump is
shipped with the inlet facing down and the outlet facing
the
muf fler.
T O CHANGE THE POSITION (See Fig 10)
1. Remove the four nuts (37) and bolts (36) from each
end of the manifold (2).
2. Turn the manifold to the desired position, and rein-
stall the bolts and nuts. T orque to 20–25 in–lb
(2.3–2.8 N.m).
NOTE: If the manifold is dif ficult to rotate, loosen the
nuts
(15) holding the v–clamps (6). Retighten af -
ter
turning the manifold.
T O CHANGE T O A DUAL MANIFOLD (See Fig 1 1)
1. If you are changing just one manifold, remove the
four nuts (37) and bolts (36) from each end of that
manifold (2). Then remove the four nuts (37) and
bolts (36) from one side of the other manifold. Re-
move
the nut (15), bolt (14) and v–clamp (6) from the
same side of the pump. Pull of f one cover (1). Re-
move
the manifold.
2. T o change both manifolds, follow Step 1, except re -
move
the nuts and bolts from both ends of both mani -
folds.
3. Install
the dual manifold, with the ports facing the de -
sired direction. Reassemble the pump. T orque the
bolts
(36) to 20–25 in–lb (2.3–2.8 N.m).

OPERATION
Flushing the Pump Before First Use
The pump was tested in water . If the solution could con -
taminate the fluid you are pumping, flush it thoroughly
with a compatible solvent. Follow the procedure in Start-
ing and Adjusting the Pump.
Starting and Adjusting the Pump
To reduce the risk of serious injury , splashing in the
eyes or on the skin, and toxic fluid spills, NEVER
move
or lift a pump under pressure. If dropped, the
fluid section may rupture. Always follow the Pres-
sure Relief Procedure Warning on page 12 be-
fore
moving or lifting the pump.
WARNING
NOTE: For Model 223–747 only , refer also to the oper -
ating instructions in Manual 308–035 for addi-
tional information regarding lube evacuation
systems.
1. Be sure the pump is properly grounded. Read and
follow
FIRE OR EXPLOSION HAZARD , on page 3.
2. Check all fittings to be sure they are tight. Be sure to
use a compatible liquid thread sealant on all male
threads.
T orque the fluid inlet and outlet fittings to 15
ft–lb (20 N.m) maximum, and the air inlet fitting to 100
in–lb (11 N.m) maximum. Do not overtighten the
fittings into the pump.
3. Place the suction tube (if used) in the fluid to be
pumped.
NOTE: If the inlet pressure to the pump is more than
25% of the outlet working pressure, the ball
check
valves will not close fast enough, resulting
in inef ficient pump operation.
4. Place the end of the outlet hose into an appropriate
container.
5.
Close the fluid drain valve.
6. With the air regulator closed, open all bleed–type
master
air valves.
7. If the outlet hose has a dispensing device, hold it
open
while continuing with the following steps.
8. Slowly open the air regulator (D) until the pump starts
to cycle. Allow the pump to cycle slowly until all air is
pushed out of the lines and the pump is primed.
If you are flushing , run the pump long enough to thor -
oughly
clean the pump and hoses. Close the air regu -
lator.
Remove the suction hose from the solvent and
place it in the fluid to be pumped.
If you are shutting down the pump , remove the suc -
tion hose from the fluid container and run the pump
until the fluid is forced out of the system. Then shut
off
the air supply immediately .
If you are going to use the pump , start the pump
again.
Place the suction hose in the supply container .
MAINTENANCE
NOTE: This information applies to all models, including
Model 223–747.
Lubrication
After every 500 hours of operation, or monthly , remove
the
hose from the pump air inlet and add two drops of ma -
chine
oil to the air inlet.
Do not over–lubricate the pump. Excess oil is ex-
hausted
through the muf fler , which could contami -
nate
your fluid supply or other equipment.
CAUTION
Flushing and Storage
Flush the pump often enough to prevent the fluid you are
pumping from drying or freezing in the pump and damag -
ing it. Always flush the pump before storing it for any
length
of time. Use a compatible solvent.
Tightening Threaded Connections
Before each use, check all hoses for wear or damage and
replace as necessary. Be sure all threaded connections
are tight and leak–free, but do not overtighten.
At least every six months, check and tighten all threaded
connections, including manifold screws, clamps, plugs,
and
valve screws. Do not overtighten.
Tightening the Clamps
When tightening the clamps (6), be sure to tighten the
bolts
(14) and nuts (15) on both sides of the pump. On the
side with the grounding strip (45), you must loosen the
nuts
above the grounding strip first. T orque the nuts un -
derneath
the strip to 6–10 ft–lb (8–14 N.m), then retorque
the nuts above the grounding strip. See Fig 1 1.
