GENERAL DESCRIPTION
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 as-
sures 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 and easy lifting of the
pump assembly from the container.
ARO systems are totally enclosed, sealing the material in the sys-
tem from air and moisture, preventing premature cure-out of the
material. This allows for either continuous or intermittent use of the
system and allows the need for daily system clean-up.
