PFPE-prepared EM pumps
8.1
Introduction
If you have ordered a PFPE-prepared EM pump, the pump will be supplied prepared for use with Edwards PFPE
mechanical pump oils, such as Fomblin 06/6 and Krytox 1506.
PFPE-prepared EM pumps are suitable for pumping high concentrations of oxygen.
We recommend that you refer to Edwards publication P300-20-000 (Vacuum pump and Vacuum System Safety) before
you install and use a PFPE-prepared EM pump.
8.2
Installation
Never use hydrocarbon lubricants in a PFPE-prepared pump.
Installation of a PFPE-prepared EM pump is as specified in
8.3
Operation
PFPE-prepared EM pumps are suitable for pumping high concentrations of oxygen, but we
recommend that you do not use a PFPE-prepared EM pump for the pumping of hazardous materials.
Operation of a PFPE-prepared EM pump is as specified in
8.4
Maintenance
Obey the safety instructions given below and take note of appropriate precautions. If you do not,
you can cause injury to people.
Take additional care if you suspect that the pump or 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 when heated to 260 °C and above. The pump may have overheated if misused, malfunctioned or
if it was in a fire. Material Safety Data Sheets for PFPE oils used in the pump are available on request:
contact your supplier or Edwards.
Fomblin oil has different properties from other pump oils, therefore:
If you fill your PFPE-prepared EM pump with Fomblin oil, we recommend that you regularly check for oil
leaks, particularly around the shaft seals.
If you detect an oil leak, contact your supplier or Edwards for advice.
