1. General information This guideline provides information on the
recommended service intervals. The recommen-
dation is based upon good engineering practice
and on experience gained from operation even
under extreme conditions.
The recommendation is for guidance only.
2. Design/features
Danfoss APP pumps are designed for long
operation and low maintenance and life cycle
costs.
Danfoss guarantees 8,000 hours service free
operation, however max. 18 months from date of
production. After 8,000 operation hours it is
recommended to inspect the pump and replace
worn parts, if any.
If the Danfoss recommendations concerning
system-design (see our data sheet) are not
followed, the service life of the APP pumps might
be aected.
The recommended service intervals on the
dierent parts in the APP pumps appear from the
table below:
