GENERAL DESCRIPTION
WARNING
DO NOT EXCEED MAXIMUM OPERATING
PRESSURE OF 6,549 P.S.I. (451.7 BAR) AT 150 P.S.I. (10.3
BAR) AIR INLET PRESSURE.
WARNING
REFER TO GENERAL INFORMATION MANUAL
INCLUDED FOR OPERATING AND SAFETY PRECAU-
TIONS AND OTHER IMPORTANT INFORMATION.
By delivering a smooth, continuous bead of the proper size,
an ARO system helps the operator maintain both production
rate and produce high quality standards. Maintained quality
standards assures that the material bene ts are realized. To
further maximize operator production time, the ARO sys-
tem has a built-in lift / ram feature for quick and easy drum
changeover and easy lifting of the pump assembly from the
container.
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 in-
termittent use of the system and reduces the need for daily
system clean-up.
The 43.6:1 ratio is an expression of the relationship between
the effective air motor area and the effective lower pump
area. When 150 p.s.i. (10.3 bar) of air pressure is supplied to
the air motor, the lower pump area will develop a maximum
of 6,549 p.s.i. (451.7 bar) of uid pressure (at no ow). As the
uid control is opened, the ow rate will increase as the air
motor cycle rate increases to keep up with the demand.
