2. Remove the (5) retaining ring and (6) connector pin to release  
the air motor piston rod from the lower pump piston rod.  
GENERAL DESCRIPTION  
3. Remove (4) spacer, (2) washer, four (3) packings, (2) washer and  
(1) wavy spring washer from the air motor cavity (see figure 2).  
The two-ball pump design provides for easy priming of the lower  
foot valve. The double acting feature is standard in all ARO indus-  
trial pumps. Material is delivered to the pump discharge outlet on  
both the up and down stroke.  
The motor is connected to the lower pump end by a spacer tube  
and solvent cup. This allows for lubrication of the upper packing  
gland and to prevent air motor contamination because of normal  
wear and eventual leakage through the material packing gland. Be  
sure the solvent cup is adequately filled with lubricant to protect  
the upper packings and insure longest service life.

Maximum Pump  
Fluid Pressure  
Pump ratio is an expression of the relationship between the pump motor area  
and the lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure  
is supplied to the motor of a 4:1 ratio pump, it will develop a maximum of 600  
p.s.i. (41.4 bar) fluid pressure (at no flow) - as the fluid control is opened, the flow  
rate will increase as the motor cycle rate increases to keep up with the demand.  
Figure 2  
Refer to general information sheet for additional  
WARNING  
safety precautions and important information.  
NOTICE: Thermal expansion can occur when the fluid in the mate-  
rial lines is exposed to elevated temperatures. Example: Material  
lines located in a non-insulated roof area can warm due to sunlight.  
Install a pressure relief valve in the pumping system.  
Replacement warning label (pn 92325) is available upon re-  
quest.

TROUBLE SHOOTING  
Retaining Ring  
Connector Pin  
Pump problems can occur in either the air motor section or the  
lower pump end section. Use these basic guidelines to help deter-  
mine which section is affected. Be sure to eliminate any possible  
non-pump problems before suspecting pump malfunction.  
REASSEMBLY  
1. Assemble (1) wavy spring washer, (2) washer, four (3) packings,  
(2) washer and (4) spacer into cavity in the air motor.  
2. Assemble the lower pump piston rod to the air motor piston  
rod, aligning the through holes.  
3. Assemble the (6) connector pin through the hole, securing with  
(5) retaining ring.  
4. Screw the lower pump assembly to the air motor.  
5. Screw the (90571) lock nut against the air motor base and  
tighten.  
Pump will not cycle.  
No pressure to the motor. See motor manual.  
Restricted return lines. Clean restriction.  
Damaged motor. Service the motor.

No material at the outlet (pump continually cycles).  
Check the material supply, disconnect or shut off the air supply  
and replenish the material, reconnect.

TOP VIEW  
Material on one stroke only (fast downstroke).  
The lower check may not be seating in the foot valve (see lower  
pump disassembly). Remove the check from the foot valve,  
clean and inspect the valve seat area. If check or foot valve are  
damaged, replace.

Material leakage out of the solvent cup or material appears on  
the pump plunger rod.  
Tighten the solvent cup until the leakage discontinues. If this  
procedure does not aid in stopping the leakage problem, the  
upper packings may be worn (see lower pump disassembly).  
Replace the seals as necessary.

DISASSEMBLY  
NOTE: All threads are right hand.  
1. Loosen the (90571) lock nut and unscrew the entire pump from  
the air motor. This will expose the (6) connector pin (see figure 2).
