Service life
Centrifuge
The service life of the centrifuge depends on several factors, e.g. the type
and frequency of use, the area of application and the performance of
service and maintenance tasks.
• The centrifuge has an expected service life of 10 years if all of the
specified maintenance intervals are observed and all of the necessary
maintenance tasks are performed without delay (see chapter 8.3 -
"Service"). Non-compliance will shorten the service life of the centrifuge
accordingly.
• The availability of spare parts can no longer be guaranteed after 10
years from the date of manufacture of the centrifuge.
Rotors and accessories
The rotors and accessories have a limited service life.
WARNING
• Perform regular checks (at least once per month) for safety reasons!
• Pay special attention to changes, such as corrosion, cracks, material
abrasion, etc.
• The rotors and accessories must be put out of service after 10 years.
Any use after this period may be permissible in individual cases after an
inspection performed by the manufacturer.
• After 50,000 cycles, the rotor must be scrapped for reasons of safety.
• If other data concerning the service life are engraved on the rotor or
bucket, these data shall apply accordingly. For example, a bucket with
the engraving "max. cycles = 10,000" has a service life of 10,000
cycles, and a rotor with the engraving "Exp. date 01/27" must be
scrapped in January 2027 at the latest (see figure below).
• If a specification concerning the maximum number of cycles
and
a
specification concerning the service life (i.e. a date) are provided, the
specification that occurs first shall apply.
