Installation  
Grounding  
Proper grounding is an essential part of maintaining a  
safe system.  
To ground the pump, loosen the grounding lug locknut  
(W) and washer (X). Insert one end of a 12 ga (1.5  
mm@) minimum ground wire (Y) into the slot in lug (Z),  
and tighten the locknut securely. Connect the other  
end of the wire to a true earth ground. To order a  
ground wire and clamp, order Part No. 222011.  
To reduce the risk of static sparking, ground the pump.  
Check your local electrical code for detailed grounding  
instructions for your area and type of equipment.

Scoop the material to the center of the drum to  
make the surface concave. Place the plate on the  
material. Guide the pump foot valve through the  
plate.  
WARNING  
Mount the pump securely so that it cannot move  
around during operation. Failure to do so could  
result in personal injury or equipment damage.  
3. Mount the pump to the drum cover or other  
suitable mounting device.  
1. Plan the mounting layout for easy operator access  
to the pump air controls, sufficient room to change  
drums and a secure mounting platform.  
4. For ease in changing drums, install a pump  
elevator.

and pressure (see WARNING at left).  
5. Install an air line filter (E) to remove harmful dirt  
and contaminants from your compressed air  
supply.  
WARNING  
Three accessories are required in your system: an  
air shut-off valve/air bleed device, fluid drain valve,  
and ground wire. These accessories help reduce  
the risk of serious bodily injury, including fluid  
injection, splashing in the eyes or on the skin,  
injury from moving parts if you are adjusting or  
repairing the pump, and explosion from static  
sparking.  
6. Install a second bleed-type master air valve (J)  
upstream from all other accessories, to isolate the  
accessories for servicing.  
D The air bleed device relieves air trapped  
between it and the air motor after the air supply  
is shut off. Trapped air can cause the air motor  
to cycle unexpectedly, causing serious injury if  
you are adjusting or repairing the pump. Use a  
bleed-type master air valve (J). Install them  
near the pump air inlet within easy reach from  
the pump.  
D The fluid drain valve (K) assists in relieving fluid  
pressure in the displacement pump, hoses, and  
dispensing valve. Triggering the valve to relieve  
pressure may not be sufficient.

CAUTION  
Do not hang the air accessories directly on the air  
inlet. The fittings are not strong enough to support  
the accessories and may cause one or more to  
break. Provide a bracket on which to mount the  
accessories.  
NOTE: Install the air line accessories in the order  
shown in Fig. 2.  
1. Install a pump runaway valve (G) to shut off the air  
to the pump if the pump accelerates beyond the  
pre-adjusted setting. A pump that runs too fast  
can be seriously damaged.  
2. Install an air line lubricator (F) for automatic air  
motor lubrication.  
3. Install a bleed-type master air valve (J) to relieve  
air trapped between the valve and the motor (see  
WARNING at left). Order Part No. 107142.

same. To reduce the risk of  
WARNING  
INJECTION HAZARD  
The equipment stays pressurized until  
pressure is manually relieved. To  
reduce the risk of serious injury from  
overpressurizing any component in the system, be  
sure you know the maximum working pressure of  
each component. Never exceed the maximum  
working pressure of the lowest rated component in  
the system. Overpressurizing any component can  
result in rupture, fire, explosion, property damage,  
and serious injury.

fluid, follow this procedure whenever you  
D Are instructed to relieve pressure  
D Stop dispensing  
D Check, clean or service any system equipment  
D Install or clean dispensing devices  
The pump has a rated ratio of 50:1. However, it is  
capable of reaching stall pressures equal to 60  
times the air input pressure. Calculate the fluid  
output pressure using the air regulator reading.  
Multiply the air pressure shown on the regulator  
gauge by 60. For example:  
1. Close the pump air regulator and the bleed-type  
master air valve (required in your system).  
2. Hold a metal part of the dispensing valve firmly to  
a grounded metal waste container and trigger the  
valve to relieve the fluid pressure.  
140 psi air x 60 = 8400 psi fluid output  
0.97 MPa air x 60 = 58.2 MPa fluid output  
9.7 bar air x 60 = 582 bar fluid output  
Startup  
1. If there are multiple pumps on the air line, close  
the air regulators and bleed-type master air valves  
to all but one pump. If there is only one pump,  
close its air regulator and bleed-type master air  
valve.  
Regulate air to the pump so that no air line or fluid  
line component or accessory is overpressurized.  
6. Never allow the pump to run dry of the material  
being pumped.  
2. Open the master air valve from the compressor.  
3. Open the dispensing valve into a grounded metal  
waste container, making firm metal-to-metal  
CAUTION  
contact between the container and valve. Open  
the bleed-type master air valve and open the pump  
air regulator slowly, just until the pump is running.  
When the pump is primed and all air has been  
pushed out of the lines, close the dispense valve.  
A dry pump will quickly accelerate to a high speed,  
possibly damaging itself. If your pump accelerates  
quickly, or is running too fast, stop it immediately and  
check the material supply. If the supply container is  
empty and air has been pumped into the lines, prime  
the pump and lines with material, or flush it and leave  
it filled with a compatible solvent. Be sure to elimi-  
nate all air from the material lines.  
4. If you have more than one pump, repeat this  
procedure for each pump.  
NOTE: When the pump is primed, and with sufficient  
air supplied, the pump starts when the dispensing  
valve is opened and shuts off when it is closed.  
NOTE: A pump runaway valve (G) can be installed on  
the air line to automatically shut off the pump if it starts  
to run too fast.  
5. Set the air pressure to each pump at the lowest  
pressure needed to get the desired results.  
7. Read and follow the instructions supplied with  
each component in your system.  
8. To shut off the system, always follow the Pressure  
Relief Procedure at the left.

straight up off of the piston. Never tilt the cylinder  
while you are removing it.  
D Two accessory tools should be ordered. Use  
Padded Pliers, 207579, to grip the trip rod without  
damaging its surface. Use Gauge, 171818, to  
ensure the proper clearance between the poppets  
and seat of the transfer valve.  
Disassembly  
WARNING  
To reduce the risk of pinching or amputating your  
fingers, always keep fingers clear of the toggle  
assemblies (L). See Fig. 5.  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 7.  
9. Use a screwdriver to push down on the trip rod  
yoke (22), and snap the toggles down. Remove  
the lockwires (31) from the adjusting nuts (30) of  
the transfer valves. Screw the top nuts off. Screw  
the stems (1a) out of the grommets (12) and  
bottom nuts. Take the valve poppets (1b) off the  
stems and squeeze them firmly to check for  
cracks. See Fig. 5.  
1. Flush the pump.  
2. Relieve the pressure before you proceed.  
3. Disconnect the hoses, remove the pump from its  
mounting, and clamp the air motor base (5) in a  
vise.  
10. Grip the toggle rockers (26) with a pliers.  
Compress the springs (27), and swing the toggle  
assembly (L) up and away from the piston lugs  
(M), and remove the parts. Check to see that the  
valve actuator (13) is supported by the spring clips  
(14), but slides easily into them. See Fig. 5.  
4. Use a strap wrench or pipe wrench on the  
extension tube (64) to screw it out of the base (5).  
See Fig. 4.  
5. Pull the extension rod (57) down as far as it will go,  
exposing the displacement rod (8).  
11. Remove the trip rod yoke (22), actuator (13), and  
trip rod (11). Check the exhaust valve poppets  
(16) for cracks.  
6. Use a hammer and punch to remove the roll pin  
(74) from the displacement rod (8), and unscrew  
the extension rod (57) out of the displacement rod.  
NOTE: To remove cracked exhaust valve poppets  
(16), stretch them out, and cut them with a sharp knife.  
CAUTION  
In step 7, do not damage the plated surface of the  
trip rod (11). A damaged trip rod could cause  
erratic air motor operation. Use the special  
padded pliers, 207579, to grasp the rod.  
12. Remove one of the air motor plates (18 or 20).  
Pull the piston (2) up out of the base (5). Remove  
the throat packing nut (38) and throat seal (6).  
7. Manually push on the displacement rod (8) to  
move the air motor piston (2) up as far as it will go.  
Unscrew the cylinder cap nut (29a or 29b). Pull  
the nut up. Grip the trip rod (11) with padded  
pliers, and screw the nut off the rod. See Fig. 4.

Reassembly  
1. Clean all the parts carefully in a compatible  
solvent, and inspect for wear or damage. Use all  
the repair kit parts during reassembly, and replace  
other parts as necessary.  
7. Install the transfer valve grommets (12), and  
reassemble the valve mechanism. Before you  
install the lockwires (31) in the adjusting nuts (30),  
use the special gauge, 171818, to adjust the  
transfer valve so there is 0.145 in. (3.7 mm)  
clearance between the poppets (1b) and the seat  
when it is open. See Fig. 5. Snap the toggles (25)  
to the up position.  
2. Check the polished surfaces of the piston (2),  
displacement rod (8), and cylinder (17) wall for  
scratches or wear. A scored rod causes  
premature throat seal wear and leaking.  
8. Reassemble the air motor, and assemble to the  
displacement pump. Torque the extension tube  
(64) to to base (5) at 45 to 55 ft-lb (61 to 75 N-m).  
Before you install the air motor plate, tighten the  
throat packing nut (38) snugly; do not overtighten  
it.  
3. Lubricate all parts with a light, water-resistant  
grease.  
4. Install the new throat seal (6), lips facing down.  
Screw the packing nut (38) into the base (5).  
5. Slide the displacement rod (8) down through the  
throat, and lower the piston (2) into the base (5).  
Be sure the o-rings (9, 10, and 24) are in place.  
See Fig. 4.  
9. Before you remount the pump, connect an air  
hose, and run the pump slowly, at about 40 psi  
(276 kPa, 2.8 bar), to see that it operates  
smoothly.  
6. Pull the exhaust valve poppets (16) into the valve  
actuator (13), and clip off the top part shown with  
dotted lines in Fig. 5.  
10. Reconnect the ground wire before regular  
operation of the pump.
