Recommended Lubrication; Normal Operation For Air Cooled Pumps - NVE MEC 5000 Owner's Manual & Operating Instructions

Testing flow 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 refined 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 fill as required.
2. When pump is in operation check oiler to insure flow 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 flush 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.
