10. PFPE-prepared RV pumps

10.1 Summary

If a PFPE-prepared RV pump has been ordered, the pump will be supplied prepared for
use with recommended PFPE mechanical pump oils, such as Fomblin YVAC 06/6 and
Krytox 1506.
PFPE-prepared RV pumps are suitable for pumping high concentrations of oxygen.
Refer to publication P40040100 (Vacuum pump and Vacuum System Safety) before
installing and using a PFPE-prepared RV pump.

10.2 Installation

CAUTION:
Never use hydrocarbon lubricants in a PFPE-prepared pump.
When filling the RV pump with oil (as described in
suitable manufacturers PFPE oil must be used. Do not use a hydrocarbon oil.

10.3 Operation

WARNING:
PFPE-prepared RV pumps are suitable for pumping high concentrations of oxygen, but
we recommend that PFPE-prepared RV pumps are not used for the pumping of
hazardous materials.
Operation of a PFPE-prepared RV pump is as specified in
note of the warning above.

10.4 Maintenance

WARNING:
Obey the safety instructions given below and take note of appropriate precautions.
Failure to do so can cause injury to people.
▪ Take additional care if it is suspected that the pump (and hence the PFPE oil) has
overheated.
▪ Do not touch or inhale the thermal breakdown products of PFPE oil which may be
present if the pump has been heated to 260 °C and above. PFPE oils are safe in
normal use but can decompose into very dangerous substances if they are heated
to 260 °C and above. The pump may have overheated if it was misused, if it
malfunctioned, or if it was in a fire. Material Safety Data Sheets for PFPE oils used
in the pump are available on request: contact us or the supplier.
