Information for transport of the vacuum pump without packaging
2 eye bolts are included in the shipment, which are firmly bolted to the vacuum pump ex-factory.
1. Unpack the vacuum pump.
2. Attach suitable lifting tools to both eye bolts.
3. Pay attention to the correct use and fastening of the lifting equipment.
4. Lift the vacuum pump out of the transport packaging vertically.
5. If necessary, remove the eye bolts after transport and installation.
– Keep the eye bolts for future use.
4.2 Storing the vacuum pump
The roots pumps do not have
any corrosion protection
on the inside. If you intend to store the roots
pump for longer periods, we recommend that you use a special corrosion protection agreed with us.
Procedure
1. Close both connection flanges.
2. Check that the other openings are sealed safely, e.g. sealing gas and measurement connections.
3. Store the roots pump only in dry, dust-free rooms, within the specified ambient conditions:
– In rooms with humid or aggressive atmospheres, seal the roots pump airtight in a plastic bag,
together with a drying agent.
– After a storage period of 2 years, Pfeiffer Vacuum recommends changing the lubricant.
The best corrosion protection for the roots pump is achieved by evacuating and then filling the suction
chamber with nitrogen.
