AIR INLET PRESSURE.
WARNING REFER TO GENERAL INFORMATION SHEET
FOR ADDITIONAL SAFETY PRECAUTIONS AND IMPORĆ
TANT INFORMATION.
By delivering a smooth, continuous bead of the proper size, an ARO
system helps the operator maintain both his production rate and proĆ
duce quality standards. Maintained quality standards assures that the
material benefits are realized. To further maximize operator production
time, the ARO System has a built-in lift/ram feature for quick and easy
drum changeover.
1
ARO Systems are totally enclosed, sealing the material in the system
from air and moisture, preventing premature cure-out of the material.
This allows for either continuous or intermittent use of the system and
reduces the need for daily system clean-up.
2
Built-in lift capability allows for quick drum changeover and easy lifting
of pump assembly from container.
The 23:1 ratio is an expression of the relationship between the effecĆ
tive air motor area and the effective lower pump area. When 150 PSI
(10 bar) of air pressure is supplied to the air motor, thelowerpumparea
will develop a maximum of 4,215 PSI (294 bar) of fluid pressure (at no
flow) as the fluid control is opened, the flow rate will increase as the air
motor cycle rate increases to keep up with the demand.
