Changing the Orientation of the Fluid Inlet
Fluid Pressure Relief Valve
and Outlet Ports
The pump is shipped with the fluid inlet (R) and outlet
(S) ports facing the same direction. See Fig. 4. To
change the orientation of the inlet and/or outlet port:
CAUTION
Some systems may require installation of a pres-
sure relief valve at the pump outlet to prevent
overpressurization and rupture of the pump or
hose. See Fig. 5.
1. Remove the screws and washers (106, 112, 113
and 114) holding the inlet (102) and/or outlet (103)
manifold to the covers (101).
Thermal expansion of fluid in the outlet line can
cause overpressurization. This can occur when
using long fluid lines exposed to sunlight or ambi-
ent heat, or when pumping from a cool to a warm
area (for example, from an underground tank).
2. Reverse the manifold and reattach. Install the
screws and washers and torque to 150–160 in–lb
(17–18 NSm). See Torque Sequence, page 31.

erratic pump operation.
WARNING
If the muffler (P) is installed directly to the air exhaust
port, apply PTFE thread tape or anti–seize thread
lubricant to the muffler threads before assembly.
FIRE AND EXPLOSION HAZARD
Be sure to read and follow the warnings
and precautions regarding TOXIC
FLUID HAZARD, and FIRE OR EXPLO-
SION HAZARD on page 4, before op-
erating this pump.
To provide a remote exhaust:
1. Remove the muffler (P) from the pump air exhaust
port.
Be sure the system is properly ventilated for your
type of installation. You must vent the exhaust to a
safe place, away from people, animals, food handl-
ing areas, and all sources of ignition when pumping
flammable or hazardous fluids.
2. Install an electrically conductive air exhaust hose
(T) and connect the muffler (P) to the other end of
the hose. The minimum size for the air exhaust
hose is 3/4 in. (19 mm) ID. If a hose longer than 15
ft (4.57 m) is required, use a larger diameter hose.
Avoid sharp bends or kinks in the hose. See Fig. 6.
Diaphragm failure will cause the fluid being
pumped to exhaust with the air. Place an appropri-
ate container at the end of the air exhaust line to
catch the fluid. See Fig. 6.
3. Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.

Operation
1. Be sure the pump is properly grounded. Refer to
Pressure Relief Procedure
Grounding on page 6.
WARNING
2. Check all fittings to be sure they are tight. Be sure
to use a compatible liquid thread sealant on all
male threads. Tighten the fluid inlet and outlet
fittings securely.
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious
injury from pressurized fluid, accidental spray from
the gun or splashing fluid, follow this procedure
whenever you:
3. Place the suction tube (if used) in the fluid to be
pumped.
D Are instructed to relieve pressure,
D Stop pumping,
D Check, clean or service any system equipment,
D Install or clean fluid nozzles.
NOTE: If the fluid 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 inefficient
pump operation.
1. Shut off the air to the pump.
2. Open the dispensing valve, if used.
4. Place the end of the fluid hose (L) into an appropri-
ate container.
3. Open the fluid drain valve to relieve all fluid pres-
sure, having a container ready to catch the drain-
age.
5. Close the fluid drain valve (J). See Fig. 2.
Flush the Pump Before First Use
The pump was tested with lightweight oil, which is left
in the fluid passages to protect parts. To avoid contam-
inating your fluid with oil, flush the pump with a com-
patible solvent before using the equipment. Follow the
steps under Starting and Adjusting the Pump.
6. With the pump air regulator (C) closed, open all
bleed-type master air valves (B, E).
7. If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
Starting and Adjusting the Pump
WARNING
8. Slowly open the air regulator (C) 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.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can
cause serious injury or death if splashed
in the eyes or on the skin, inhaled, or
swallowed. Do not lift a pump under pressure. If
dropped, the fluid section may rupture. Always fol-
low the Pressure Relief Procedure above before
lifting the pump.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the
air regulator. Remove the suction tube from the
solvent and place it in the fluid to be pumped.

Operation
NOTE: Leaving air pressure applied to the air motor for
Operation of Remote Piloted Pumps
extended periods when the pump is not running may
shorten the diaphragm life. Using a 3–way solenoid
valve to automatically relieve the pressure on the air
motor when the metering cycle is complete prevents
this from occurring.
1. Fig. 2 and Parts Drawings. Follow preceding steps
1 through 7 of Starting and Adjusting Pump.
2. Open air regulator (C).
Pump Shutdown
WARNING
The pump may cycle once before the external sig-
nal is applied. Injury is possible. If pump cycles,
wait until end before proceeding.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
3. Pump will operate when air pressure is alternately
applied and relieved to push type connectors (14).
At the end of the work shift, relieve the pressure.
Maintenance
Flush the pump often enough to prevent the fluid you
are pumping from drying or freezing in the pump and
damaging it. Flush with a fluid that is compatible with
the fluid you are pumping and with the wetted parts in
your system. Check with your fluid manufacturer or
supplier for recommended flushing fluids and flushing
frequency.
Lubrication
The air valve is designed to operate unlubricated.
However, if lubrication is desired, every 500 hours of
operation (or monthly) remove the hose from the pump
air inlet and add two drops of machine oil to the air
inlet.
Always flush the pump and relieve the pressure before
storing it for any length of time.
CAUTION
Tightening Threaded Connections
Do not over-lubricate the pump. Oil is exhausted
through the muffler, which could contaminate your
fluid supply or other equipment. Excessive lubrica-
tion can also cause the pump to malfunction.
Before each use, check all hoses for wear or damage,
and replace as necessary. Check to be sure all
threaded connections are tight and leak free. Check
fasteners. Tighten or retorque as necessary. Although
pump use varies, a general guideline is to retorque
fasteners every two months. See Torque Sequence,
page 31.
Flushing and Storage
WARNING
Preventive Maintenance Schedule
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 12.
Establish a preventive maintenance schedule, based
on the pump’s service history. This is especially impor-
tant for prevention of spills or leakage due to dia-
phragm failure.

Fig. 13.
shaft (24). Remove one diaphragm (401), and the
inner plate (104). See Fig. 13.
For overmolded diaphragms: Grip both dia-
phragms securely around the outer edge and
rotate counterclockwise. One diaphragm assembly
will come free and the other will remain attached to
the shaft. Remove the freed diaphragm and air
side plate.
2. Grease the length and ends of the diaphragm shaft
(24) and slide it through the housing (1).
3. Assemble the inner diaphragm plates (104), dia-
phragms (401*), PTFE diaphragms (403*, if pres-
ent), and outer diaphragm plates (105) exactly as
shown in Fig. 13. These parts must be assembled
correctly.
NOTE: PTFE models include a PTFE diaphragm (403)
in addition to the backup diaphragm (401).
5. Pull the other diaphragm assembly and the dia-
phragm shaft (24) out of the center housing (1).
Hold the shaft flats with a 19 mm open–end
wrench, and remove the outer plate (105) from the
shaft. Disassemble the remaining diaphragm
assembly.
4. Apply medium-strength (blue) LoctiteR or equiva-
lent to the threads of the fluid-side plates (105).
Hold one of the outer plates (105) with a wrench,
and torque the other outer plate to 20 to 25 ft-lb
(27 to 34 NSm) at 100 rpm maximum. Do not
over-torque.
For overmolded diaphragms: Pull the other dia-
phragm assembly and the diaphragm shaft (24)
out of the center housing (1). Hold the shaft flats
with a 19 mm open–end wrench and remove the
diaphragm and air side plate from the shaft.
5. Align the fluid covers (101) and the center housing
(1) so the arrows (A) on the covers face the same
direction as the air valve (B). Secure the covers
with the screws (107 and 108), handtight. Install
the longer screws (108) in the top and bottom
holes of the covers. See Fig. 12.
6. Inspect the diaphragm shaft (24) for wear or
scratches. If it is damaged, inspect the bearings
(19) in place. If the bearings are damaged, refer to
page 23.
6. First, torque the longer screws (108) oppositely
and evenly to 190–220 in-lb (21–25 NSm), using a
13 mm socket wrench. Then torque the shorter
screws (107). See Torque Sequence, page 31.
7. Reach into the center housing (1) with an o-ring
pick and hook the u-cup packings (402), then pull
them out of the housing. This can be done with the
bearings (19) in place.
8. Clean all parts and inspect for wear or damage.

Reassembly – Overmolded Diaphragms
5. Assemble the other diaphragm assembly to the
shaft as explained in step 2. This diaphragm will
be lifted off the air cover at this point.
WARNING
To reduce the risk of serious injury, including
amputation, do not put your fingers or hand be-
tween the air cover and the diaphragm.
6. Supply the pump with low pressure air (less than 7
psi [0.05 MPa, 0.5 bar]). The diaphragm will very
slowly pull onto the air cover. Find the pressure
that keeps the diaphragm close enough to secure
with the screws, but does not let it contact the pilot
pin.
1. Lubricate and install the shaft u–cup packings
(402*) so the lips face out of the housing (1). See
Fig. 13.
NOTE: Do not deform the diaphragm manually. The
diaphragm needs uniform pressure to deform properly
for maximum life.
2. Assemble the air side plate (104) onto the dia-
phragm (403). The wide, radiused side of the plate
must face the diaphragm. Apply medium–strength
(blue) Loctite or equivalent to the threads of the
diaphragm assembly. Screw the assembly into the
shaft (24) hand–tight.
7. Align the fluid cover (101) and the center housing
(1) so the arrow (A) faces the same direction as
the air valve. Secure the cover with two of the
longer screws (108), handtight.
NOTE: If the diaphragm contacts the pilot pin and is
forced away from the air cover, try Step 5 again. If
necessary, return to Step 3.
3. Grease the length and ends of the diaphragm shaft
(24). Insert the shaft/diaphragm assembly into one
side of the pump. Align the fluid cover (101) and
the center housing (1) so the arrow (A) faces the
same direction as the air valve. Secure the cover
with the screws (107 and 108), handtight.
8. Torque the longer screws (108) oppositely and
evenly to 190–220 in–lb (21–25 NSm), using a
13mm socket wrench. Then torque the shorter
screws (107). See Torque Sequence, page 31.
4. Torque the longer screws (108) oppositely and
