INTRODUCTION
The ULVAC-PKS Series pumps are suitable for industrial use in medium or high
vacuum pumping systems.
The PKS Series are self-contained rotary, oil sealed piston type units, and are
designed for the best possible stability and small floor space, and have well proven
reliability. We recommend that you use "ULVOIL-R-7" rotary pump oil specified
by ULVAC for best results. However, any good quality mechanical vacuum pump
oil is suitable with the PKS Series, although we do suggest that you consult with a
vacuum specialist first.
