9. Service
Danfoss PAHT G pumps are designed for long
periods of service-free operation to ensure low
maintenance and life cycle costs. Provided that
the pump is installed and operated according to
Danfoss specifications, Danfoss PAHT G pumps
typically run up to 8,000 hours. However, the
service schedule for your Danfoss PAHT G pump
may vary according to the application and other
factors.
The life of a pump may be greatly shortened if
Danfoss recommendations concerning system
design and operation are not followed.
In our experience, poor filtration is the number
one cause of pump damage.
Other factors that affect pump performance and
lifetime include:
• running the pump at speeds outside
specifications
• supplying the pump with water at tempera-
tures higher than recommended
• running the pump at inlet pressures
outside specifications
• running the pump at outlet pressures
outside the specifications.
We recommend that you inspect your pump
after 8,000 hours of operation even if it is running
without any noticeable problems. Replace any
worn parts if necessary, including pistons and
shaft seals, to keep your pump running efficiently
and to prevent breakdown. If worn parts are not
replaced, then our guidelines recommend more
frequent inspection.
