If the pump performance is within acceptable limits, or is performing sasfactorily, the
p‑seal replacement can be delayed.
If operang a preventave maintenance plan, depending upon the parcular regime, a
p‑seal change can be carried out at this me irrespecve of the pump performance.

Refer to Tip-seal kit on page 52 for ordering informaon.
A p-seal replacement should be carried out to maintain or restore the pumps
performance. The frequency for replacing the pump p‑seals is determine by the
following factors:
▪ The pump has reached a service interval. Refer to Check the pump perf
ormance
(service indicator) on page 40 and Replace the pump bearings (service indicator) on
page 40.
▪ The pump is no longer achieving the required performance.
If the pump is no longer achieving the required performance prior to a service interval
being reached, we recommend you to follow the guide lines, refer to The pump has
failed to achieve the required performance on page 43.
Note:
There may be a running
‑ in period aer ng your new p ‑ seals. The performance
