5.2 Oil specifications
It is strongly recommended to use genuine Edwards Lubricants. They are the result of years of field
experience and research. See section Preventive maintenance schedule for the advised replacement
intervals and consult your Spare Parts list for part number information.
CAUTION
Avoid mixing lubricants of different brands or types as they may not be compatible and the oil mix may
have inferior properties.
Vacuum vanes fluid plus 100
Vacuum vanes fluid plus 100 is a specially developed lubricant that can be used in the gearbox of the claw
pump. It’s specific composition keeps the vacuum pump in excellent condition.
5.3 Storage
If the pump is to be stored for a short time then it is advisable to take some precautions. Always isolate
the pump from the suction inlet and exhaust outlet. Make sure it is clean and dry from process or
condensation within the element. In order to keep rubber parts and lip seals efficient and properly
working, we recommend to operate the pump for at least 30 minutes every 6 months with the intake
closed.
Ideally the pump should be covered to protect from mechanical damage and kept clean, dry and isolated.
Long-term storage needs a little more consideration. It is best to ask for further advice from Edwards
especially when a restart / decommissioning is required.
If the pump is going to be stored without running from time to time, protective measures must be taken.
Consult Edwards.
5.4 Disposal of used material
Used lubricants or any other used material (for example, cleaning rags, machine parts, and so on) must be
disposed of in an environmentally friendly and safe manner, and in line with the local recommendations
and environmental legislation.
