When making adjustments do so
one turn of the screw at a time and test

starve the vacuum pump of oil.
Recommended lubrication
We recommend that turbine grade oil be used in all our pumps.
Turbine oil is more highly refined than motor oil and is much less
likely to create carbon. Turbine oil is available from your local oil
distributor. Below is a list of acceptable oils.
•
Penzoil Penzabell 68 T.O.
•
Shell Turbo 68
•
Mobil D.T.E. Heavy – Medium
Recommended Lubricant
• We recommend that turbine oil be used in our pumps. Turbine
oil is much more resistant to breakdown due to heat than nor-
mal motor oil, thereby avoiding the problems associated with
motor oil such as lacquering and excessive wear.
• Acceptable oils include:
1. *NVE ISO 68 Oil
2. Penzoil Penzabell 68 T.O.
3. Shell Turbo 68
4. Mobil D.T.E. Heavy - Medium
5. Texaco Regal R & O 68
* NVE ISO 68 Oil is our recommended pump oil for the
Challenger series vacuum pumps. Challenger Vacuum Pump Oil is
sold by the case, six 1 gallon containers of oil per case.
