5 Maintenance
5.1 Leybold Service
Whenever you send us in equipment, indicate whether the equipment is con-
taminated or is free of substances which could pose a health hazard. If it is
contaminated, specify exactly which substances are involved. You must use
the form we have prepared for this purpose.
This form is available from
www.leybold.com -> Downloads -> Download Documents.
Attach the form to each pump.
This statement detailing the type of contamination is required to satisfy legal
requirements and for the protection of our employees.
We must return to the sender any equipment which is not accompanied by a
contamination statement.
5.2 Maintenance Intervals
See the table for the recommended maintenance intervals for the pumps. We
recommend a service contract with Leybold.
We recommend to inspect the pump system and all components after
approximately 6 months under the process conditions. The inspection of the
components shall let corrosion attacks become apparent at an early stage
and indicate possible deposits of process dust. Depending on the findings,
changed maintenance and replacement intervals can become necessary for
specific components.
