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 aected.
The recommended service intervals on the
dierent parts in the APP pumps appear from the
table below:

The pistons are the heart of the pump regarding
service.
If the pistons break down, the pump will suer a
breakdown.
In case of doubt - the pistons must be replaced.
The pictures below is ment as a guideline for
evaluating the wear of the sliding surface.
Cavitation of the piston shoes.
New inspection is required in 3,000-4,000 hours.
Cavitation of the piston shoes.
All pistons must be replaced within the next
500-1,000 hours.
Cavitation of the piston shoes.
All pistons must be replaced within the next
100-200 hours.
Cavitation of the piston shoes.
All pistons must be replaced immediately.
