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 fi lled with lubricant to protect 
the upper packings and insure longest service life.

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) fl uid pressure (at no fl ow) - as the fl uid control is opened, the fl ow 
rate will increase as the motor cycle rate increases to keep up with the demand.

NOTICE: Thermal expansion can occur when the fl uid 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.

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.

No pressure to the motor. See motor manual.
Restricted return lines. Clean restriction.
Damaged motor. Service the motor.

Check the material supply, disconnect or shut off  the air supply 
and replenish the material, reconnect.

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.

The middle packings may be worn (see lower pump disassem-
bly). Replace the seals as necessary.

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.

Loosen the (90571) lock nut and unscrew the entire pump from 
the air motor. This will expose the (6) connector pin (see fi gure 
2).
Remove the (5) retaining ring and (6) connector pin to release 
the air motor piston rod from the lower pump piston rod.
Remove (4) spacer, (2) washer, four (3) packings, (2) washer and 
(1) wavy spring washer from the air motor cavity (see fi gure 2).

Assemble (1) wavy spring washer, (2) washer, four (3) packings, 
(2) washer and (4) spacer into cavity in the air motor.
Assemble the lower pump piston rod to the air motor piston 
rod, aligning the through holes.
Assemble the (6) connector pin through the hole, securing with 
(5) retaining ring.
Screw the lower pump assembly to the air motor.
Screw the (90571) lock nut against the air motor base and 
tighten.
