It is the responsibility of the employer to place this information in the hands of the operator. Keep for future reference.
SERVICE KITS
•61268 for repair of Air Motor section.
•61053 for repair of entire pump.
•65823 for repair of Base Packing.
•Use only genuine ARORreplacement parts to assure compatible
pressure rating and longest service life.
GENERAL DESCRIPTION
This model is designed for high volume delivery of low viscosity fluids
from standard containers. The model covered by this manual includes
an outlet swivel, material supply hoses and airline lubricator. Material
dispensing accessories and supply lines and fittings must be capable of
withstanding pressures developed by the pump.
•The AROR9:1 ratio basic pump assembly consists of 4-1/4” air mo-
tor and two ball lower pump end.
PUMP RATIO X
INLET PRESSURE TO PUMP MOTOR =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 bar) inlet pressure is
supplied to the motor of a 9:1 ratio pump it will develop a maximum of 1350 p.s.i.
(93 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.
AIR AND LUBE REQUIREMENTS
WARNING HAZARDOUS PRESSURE. Do not exceed maxi-
mum inlet air pressure of 150 psi (10 bar). Operating pump at
higher pressure may cause pump damage and/or personal in-
jury and/or property damage.
WARNING Refer to general information sheet for additional
safety precautions and important information.
•Excessive air pressure will shorten the life of the pump.
•For maximum operating efficiency, the following air supply specifica-
tions should be maintained to this pump.
•AIR PRESSURE - Up to 150 P.S.I. (10 Bar)
•AIR FILTRATION - 50 micron
•LUBRICATED AIR SUPPLY
•AIR INLET SIZE - 1/2” NPTF

AIR AND LUBE REQUIREMENTS (cont)
•Filtered and oiled air will allow the pump to operate more efficiently
and yield a longer life to operating parts and mechanisms.
•Lack of or an excessive amount of lubrication will affect the perfor-
mance and life of this pump. Use only recommended lubricants.
•DAILY Fill air line lubricator with a good grade of S.A.E. NO. 90W
non-detergent gear oil, adjust to 1 to 2 drops per minute.
•If pump is to be inoperative for more than a few hours at a time, dis-
connect air supply and relieve all pressure from the system.
It is recommended that an oiler be installed in the air line as close as pos-
sible to the pump. This increases the service life of the pump by reducing
wear of the air motor’s internal parts.
TROUBLE-SHOOTING
Should pump operate, but dispense little or no material, check for:
•Inadequate supply of material or possible malfunctioning of 77006
Foot Valve which would prevent material from feeding into suction
tube.
•Dirt or foreign matter in 77006 Foot Valve or other cause which may
be preventing it from closing on downstroke of piston.
If unit should fail to operate, the following procedure will be helpful in de-
termining the cause:
•Check air pressure at pump to insure air line is not obstructed and air
is being supplied to pump.
•If insufficient air is not the trouble, disconnect air supply to pumpand
then detach Hose and Gun at 75367 Swivel. REMOVESLOWLYAS
PRESSURE MAY BE BUILT UP IN PUMP. Hold rag at this point and
apply air to pump. If pump now operates, there is obstruction in ma-
terial line, reel, or control handle. If, however, pump will still not oper-
ate, consult local dealer,
