protection, containing detergent dispersants, with excellent flow characteristics at low temperature. It has a
viscosity of 430 SSU at 100 Deg. F. (38 Deg. C), and 82 SSU at 210 Deg. F. (99 Deg. C), w ith a vapor
pressure of 0.0001 mm Hg. at 145 Deg. F. (63 Deg. C)
If the pump is to be operated at vacuum levels that cause the oil temperature to exceed 160 Deg. F. (71 Deg. C)
for extended periods of time, a heavier grade oil should be used. Stokes V-Lube (Label G) is available for oil
temperatures up to 200 Deg. F. (94 Deg. C).
Special operating conditions may require the use of special oils. Consult Stokes Vacuum for specific
recommendations w hen other than regular petroleum oils are being used.
