Oerlikon Leybold Vacuum
Pump Oils
If you want good performance and long service from your Leybold
or any other vacuum pump, it is essential to use the recommended
oil and to ensure that the oil is clean. Change the oil as soon
as there is any sign of degradation. Protecting your pump
with the proper inlet filter and/or filtering system keeps the oil
clean for longer periods and extends the life of the oil and the
pump.

Which Leybold vacuum pump oils do Vacuum Products Canada
and Oerlikon Leybold recommend?
 | HE-100 hydrocarbon oil is standard oil
for Leybold
Sogevac pumps SV100 and smaller. HE-100 has excellent
resistance to auto oxidation and good water separating
characteristics. It has rust oxidation inhibitors and is similar to
HE-700 except that it has lower viscosity better for smaller pumps. French

| HE-125 hydrocarbon oil is recommended for Leybold
Sogevac pumps in food processing and food packaging
applications. HE-125 FG (food grade) oil is recommended for use in
food processing and food packaging applications where pump oil may come in
contact with edible products. It is rated H-1 by the US Department of
Agriculture which authorizes its use under the Federal Meat and Poultry
Inspection Program. All components of HE-125FG are also approved for
incidental food contact by the Food and Drug Administration under CFR21,
Section 178.3570. Contamination of food with this oil must not exceed
10 ppm. HE-125FG contains an effective anti-oxidant that inhibits
rust, sludge and varnish formation. French
MSDS |
| HE-150 hydrocarbon oil for Leybold
E and DK, RAV and Ruvac standard applications. HE-150 has
excellent water separating characteristics which prevent emulsion
formation. It is more viscous than most of our other vacuum
oils. French MSDS |
| HE-175 hydrocarbon oil for Leybold
Trivac A standard applications. HE-175 is a durable oil with
good lubrication qualities and low vapour pressure to prevent backstreaming.
It is effective at normal operating temperature where cleanliness of the
system is important. French MSDS |
| HE-200 hydrocarbon oil for Leybold Ruvac, Leybold Trivac B,
BCS,
and E standard applications,
Trivac A, E and DK corrosive applications. HE-200 is
more corrosive resistant than HE-175; it withstands acids, alkalies and
other corrosives better than standard vacuum pump oils. French
MSDS |
| HE-270 synthetic hydrocarbon
oil for Leybold Sogevac pumps SV100 and smaller in high temperature
applications. HE-270 is used for high temperature
applications. It has an oxidation inhibitor and is well suited for use
in Sogevac pumps that pump organic solvent vapour. |
| HE-300 |
| HE-400 hydrocarbon oil for Trivac B/BCS
standard applications and Trivac A, Ruvac, E and DK corrosive
applications. HE-400 is a clear colourless oil that lasts longer than
HE-200 in corrosive applications. Aromatics, unsaturated hydrocarbons
and emulsifying agents have been significantly removed from HE-400 making it
suitable for use with most reactive or corrosive process gases.
Aromatics and unsaturated bonds are preferential sites for chemical
reactions resulting in premature oxidation and sludge formation. French
MSDS |
| HE-500 synthetic diester fluid for Leybold
Turbovac standard and corrosive applications. HE-500 has
very low viscosity and low volatility. It has corrosion and oxidation
inhibitors and is more stable than a mineral oil. The high speed
bearings in a turbomolecular pump require a low viscosity oil. |
| HE-600 diester hydrocarbon oil for Leybold Trivac,
Sogevac, Ruvac,
E and DK high temperature applications. HE-600 is a diester
hydrocarbon oil with corrosion and oxidation inhibitors, low volatility, and
good water separating characteristics. It can withstand high
temperatures much better than standard hydrocarbon oil. the maximum
oil-sump temperature of a pump using HE-600 is about 300°F; consult the
factory if your pump will exceed 300°F. HE-600 should be used in
applications where standard hydrocarbon oil quickly cracks and forms sludge
as the result of high temperature. HE-600 is unsuitable for pumping
mineral acids because the ester decomposes. HE-600 is miscible and
compatible with mineral oils. However, when switching from mineral oil
to HE-600, flush and refill the pump to ensure that residual mineral does
not degrade the oil's thermal resistance. |
| HE-700 hydrocarbon oil, standard oil for Leybold
Sogevac SV40 and larger. HE-700 has excellent resistance to
auto oxidation and good water separating characteristics. It has rust
and oxidation inhibitors. HE-700 is similar to HE-100 except that it
has higher viscosity which is better for the larger pumps. French

Corrosive and Oxygen Applications
PFPE (perfluopolyether) oils are recommended for pumping extremely
reactive gases. PFPE oils must be used if the process gas could react with
hydrocarbon vacuum oil to create a fire or explosion hazard. Because of
their high molecular weight and their relative chemical inertness, PFPE oils are
also suitable for processes requiring an ultra-clean vacuum.
All PFPE oils that we sell are compatible with each other. The PFPE
oils that we recommend are guaranteed to meet their specified vapour
pressure. However, the pump's ultimate pressure is about one decade higher
when using PFPE than it is for the same pump using hydrocarbon vacuum oil.
Another disadvantange of PFPE is that it doesn't conduct heat as well as
hydrocarbon oil, resulting in higher pump operating temperatures.
When using this fluid we recommend a CFS chemical filtering system to keep
your oil clean and extend its useful life. PFPE
doesn't keep contaminants suspended as well as mineral oil; an oil filtering
system removes most contaminant deposits before they cause damage to the pump.
Use an activated alumina element to protect PFPE from Lewis Acids.
PFPE has outstanding
resistance to oxygen. nitrogen oxides, ozone, alkalies, acid vapors, fluorine
and other halogens. However, PFPE can decompose and produce volatiles in
the presence of Lewis acids such as
BCl3 and AlCl3 at temperatures exceeding 212°F. You will
notice a slow steady decrease in the PFPE level in your pump if PFPE is reacting
with contaminants.
When PFPE decomposes, toxic
gases are formed. Don't use open flame in rooms where PFPE is being used since
PFPE could decompose in the heat of the flame.
If contaminants accumulate in
the pump, run the pump with the inlet closed, the gas ballast valve open, a
clean oil filter, and inert gas purging on the oil case. If the PFPE isn't
contaminated with hazardous media, you can also try draining the PFPE, allowing
it to sit for at least 24 hours while the heavy contaminants settle out, and
then decanting the light contaminants. However, some contaminants won't separate
and must be removed by a reclamation vendor.
PFPE is NOT compatible with
hydrocarbon oils, solvents, or greases! When converting from hydrocarbon oil to
PFPE or vice-versa, the pump must be completely disassembled and degreased.
Then, new seals, vanes, and filter elements must be installed. The following
problems occur if any residual hydrocarbons remain in a PFPE pump:
|
Residual hydrocarbons
could have a dangerous reaction with the process gas |
|
PFPE and hydrocarbon oil
emulsify causing poor lubrication |
|
Residual hydrocarbons
react with process gas to form contaminants that damage the
seals |
|
If the shaft seal retains
some hydrocarbon oil on its surface, this oil acts as a lubricant
allowing the PFPE to leak past the seal. |
When working on a pump that
uses PFPE oil, ensure that its inner parts don't come into contact with
hydrocarbons or moisture. Use clean gloves and ensure that the room, tools and
working surfaces are clean and dry. Don't use hydrocarbon solvents, acetone,
alcohol, or any other solvents that could have a dangerous reaction
with highly reactive process gases. If grease is needed, use a PFPE grease.
Don't eat, drink or smoke while working on
the pump.
Because PFPE doesn't protect
the degreased metal surfaced against corrosion, exposure
to water vapor and corrosive gases should be kept to a minimum. We recommend
running PFPE pumps continuously. If you must shut down the pump, seal the inlet
line and run the pump with inert gas ballasting for at least 12 hours. After
switching off the pump, change the PFPE oil and any oil filters, and flush the
pump with dry inert gas at the inlet, oil case, and gas ballast valve for 30
minutes to remove any water vapor and residual contaminants. Then, seal the
inlet and exhaust while the pump is warm to prevent water vapor from entering
during shutdown. The used PFPE can be sent to a reclamation vendor for reuse.
| HE-1600 PFPE fluid is recommended for
use in Trivac A, E and B/BCS vane pumps, Sogevac vane pumps and Ruvac roots
pumps. |
| HE-2700 is recommended for use in E and DK pumps and can also be used in
Ruvac roots pumps. |
| HE-1200 is used only in the TMP450 corrosive-series turbomolecular
pump. Its viscosity is similar to HE-500 which is the standard
hydrocarbon oil. The standard TMP450 must be modified by Leybold
before it can use HE-1200 PFPE oil. |
