11.  PFPE-prepared EM pumps

If a PFPE-prepared EM pump has been ordered, the pump will be supplied prepared for

use with the manufacturers PFPE mechanical pump oils, such as Fomblin YVAC 06/6 and

Krytox 1506.
PFPE-prepared EM pumps are suitable for pumping high concentrations of oxygen.
We recommend referring to publication P40040100 (Vacuum pump and Vacuum System

Safety) before installing and using a PFPE-prepared EM pump.

11.1  Installation

CAUTION:

Never use hydrocarbon lubricants in a PFPE-prepared pump.

Installation of a PFPE-prepared EM pump is as specified in 

Installation on page 17

, but

take note of the caution above.

11.2  Operation

WARNING:

PFPE-prepared EM pumps are suitable for pumping high concentrations of oxygen,

but We recommend that a PFPE-prepared EM pump is not used for the pumping of

hazardous materials.

Operation of a PFPE-prepared EM pump is as specified in 

Operation on page 28

, but take

note of the warning above.

11.3  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. Safety Data Sheets for PFPE oils used in the

pump are available on request: contact us or the supplier.

Fomblin oil has different properties from other pump oils, therefore:
