To maintain the high vacuum pump...
For maximum performance, Robinair recommends changing vacuum
pump oil after each use.
The condition and type of oil used in any high vacuum pump are
extremely important in determining the ultimate attainable vacuum.
Robinair recommends the use of our Premium High Vacuum Pump Oil.
This oil has been specifically blended to maintain maximum viscosity at
normal running temperatures and to improve cold weather starts.
Robinair Premium High Vacuum Pump Oil is available in handy quart
containers or in convenient gallon containers. Order by part number:
13203 — Quart (shipped 12 quarts per case)
13204 — Gallon (shipped 4 gallons per case)
1. Allow the pump to run until it is warmed up.
2. Remove the OIL DRAIN cap. Drain contaminated oil into a suitable
container and dispose of it according to the regulations in your
jurisdiction. Oil can be forced from the pump by opening the inlet and
partially blocking the exhaust with a cloth while the pump is running. Do
not operate the pump for more than 20 seconds using this method.
3. When the flow of oil has stopped, tilt the pump forward to drain
residual oil.
4. Replace the OIL DRAIN cap. Remove the OIL FILL cap, and fill the
reservoir with new vacuum pump oil until the oil just shows at the
bottom of the sight glass. The approximate oil capacity of the pump
is 15 ounces.
5. Verify the inlet ports are capped, and turn ON the pump. Allow it to run
for one minute, and check the oil level. If the oil is below the sight glass
OIL LEVEL line, add oil slowly (with the pump running) until the oil
reaches the OIL LEVEL line. Replace the OIL FILL cap, making sure the
inlet is capped and the drain cap is tight.
6. a) If the oil is badly contaminated with the sludge that forms when
water is allowed to collect in the oil, you may need to remove the oil
reservoir cover and wipe it out.
