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

INLET PRESSURE TO PUMP MOTOR
PUMP RATIO X
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 (cont)
TROUBLE-SHOOTING
• 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 inthe air line asclose as possible to the pump. This increases the service lifeof the pump by reducing
wear of the air motor’s internal parts.
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 determining the cause:
• Check air pressure at pump to insure air line is notobstructed and air
is being supplied to pump.
• If insufficientair is not the trouble, disconnect air supply to pump and
then detach Hose andGun at75367 Swivel.REMOVE SLOWLYAS
PRESSURE MAYBE BUILTUP IN PUMP.Hold rag at this point and
apply air to pump. If pump now operates, there is obstruction in material line,reel, or control handle.If, however,pump will still not operate, consult local dealer,
