If a check shows a bad running of the
motor pump unit, the user must:
a) Refer to the "fault finding chart" chapter
7 of this leaflet to apply the recommended
solutions.
b) Ensure that your equipment corresponds to
the arrangements of this leaflet.
c) Contact Flowserve after-sales Department if
the problem persists.
6.2.4 Mechanical seals
The current maintenance is limited to seal control.
It is necessary to detect any small leakage which
announces the beginning of the deterioration of
friction faces or secondary seal elements (rings,
bellows, synthetic membranes).
It is advisable to stop the pump as soon as
possible. Have an approved seal vendor replace or
repair the seal.
6.2.5 Internal coating
If the pump has an internal coating, this coating
must be inspected periodically. Any wear or cracks
of the coating found must be immediately repaired.
Failure to do this may lead to accelerated wear of
the coating during operation and corrosion of the
exposed base metal, depending on the material
and pumped liquid.
Special attention must be paid to the coating
edges. Any loss of coating material is considered
to be normal wear and tear on the pump and is not
considered as warranty.
Flowserve has applied the coatings according to
the supplier's instructions but will not be held
responsible for coating wear or cracks that may
develop over time.
6.3 Spare parts
6.3.1 Ordering of spares
Flowserve keeps records of all pumps that have
been supplied. When ordering spares the following
information should be quoted:
1) Pump serial number.
2) Pump size.
3) Part name
4) Part number
5) Number of parts required.
The pump size and serial number are shown on
the pump nameplate.
To ensure continued satisfactory operation,
replacement parts to the original design
specification should be obtained from Flowserve.
Any change to the original design specification
(modification or use of a non-standard part) will
invalidate the pump’s safety certification.
6.3.2 Storage of spares
Spares should be stored in a clean dry area away
from vibration. Inspection and re-treatment of
metallic surfaces (if necessary) with preservative is
recommended at 6 monthly intervals.
6.4 Recommended spares and
consumable items
We advise you to stock the components indicated
by
* on the "Parts List".
6.4.1 Gaskets
Change all the gaskets after each dismantling.
6.4.2 Mechanical seal
Change the mechanical seal when it leaks or if it is
damaged (broken, jagged friction face) after
dismantling or reassembly.
6.5 Disassembly
Refer to section 1.6, Safety, and section 6
Maintenance, before dismantling the pump.
Before dismantling the pump for
overhaul, ensure genuine Flowserve replacement
parts are available. Refer to sectional drawings for
part numbers and identification.
