APP pumps - APP 1.5-3.5
12.1 Warranty
Danfoss APP pumps are designed for long
operation, low maintenance and reduced
lifecycle costs.
Provided that the pump has been running
according to the Danfoss specifications, Danfoss
guarantees 8,000 hours service-free operation,
however, max. 18 months from date of produc-
tion.
If Danfoss recommendations concerning
system-design are not followed, it will strongly
influence the life of the APP pumps.
12.2 Maintenance
After 8,000 hours of operation it is strongly
recommended to inspect the pump and
change any worn parts, e.g. pistons and shaft
seal. This is done in order to prevent a potential
breakdown of the pump.
If the parts are not replaced, more frequent
inspection is recommended according to our
guidelines.
Standstill
The APP pumps are made of Duplex/Super
Duplex materials with excellent corrosion
properties. It is, however, always recommended
to flush the pump with freshwater when the
system is shut down.
