Testing ow rate after adjustment
1. Observe oil drip rate in oil view meter or oil line to ensure
adequate lubrication.
2. Adjustments should be done gradually so as not to starve
the vacuum pump of oil.
Recommended lubrication
We recommend that turbine grade oil be used in all our pumps. Tur-
bineoilismorehighlyrenedthanmotoroilandismuchlesslikely
to create carbon. Turbine oil is available from your local oil distribu-
tor. Below is a list of acceptable oils.
• PenzoilPenzabell68T.O.
• ShellTurbo68
• MobilD.T.E.Heavy–Medium
• TexacoRegalR.N.O.68
Normal operation for air cooled pumps:
1. Check oilreservoirdailyandllasrequired.
2. When pump is in operation check oilertoinsureowofoil
to pump.
3. Do not operate pump faster than recommended RPM.
4. To operate suction valve on top of pump, move handle in
the appropriate direction for either vacuum or pressure;
center it for neutral.
5. We recommend checking vane wear every twelve months.
Anewvaneisnearlyushwiththerotor.Measurethe
wear and if is over 1/4” we recommend replacing vanes.
It’s good to always keep a spare set of vanes on hand for
emergencies.
