6.2 Maintenance schedule
NOTE Not all components or sub-
assemblies of a pumping unit are
necessarily supplied by Flowserve
or part of this delivery.
These user instructions apply only
to the components or sub-
assemblies supplied by Flowserve
in this delivery, see Chapter 12.1
"Scope of delivery".
Flowserve submersible pumps are custom de-
signed to operate for extended periods with a
minimum of regular maintenance, the frequency
and scope of maintenance depending primarily on
the conditions of service to which the pump is sub-
ject. Periodic dismantling for inspection is not nec-
essary unless excessive wear is indicated or a
pump malfunction is suspected.
To determine when major maintenance is required,
periodic testing of the pumping unit (as described
in Chapter 6.7 "Periodic testing", Page 52) is
strongly recommended. This will establish a base-
line of performance data indicative on pump condi-
tion that will permit scheduling of major mainte-
nance tasks well ahead of the time they become
necessary and will prove very beneficial to the pro-
longed lift and satisfactory operation of the pump-
ing unit.
Interval Part Maintenance
All parts Inspect all piping connections for evidence of leakage, loosening or
other damage and repair if necessary. Before each installation and after
each uninstallation

due to vibration, and tighten if necessary.
