6.2.1 Routine Inspection (daily/weekly)
The following checks should be
made and the appropriate action taken to remedy any
deviations.
a) Check operating behavior; ensure noise, vibration
and bearing temperatures are normal.
b) Check that there are no abnormal fluid or
lubricant leaks (static and dynamic seals) and
that any sealant systems (if fitted) are full and
operating normally.
c) Check that shaft seal leaks are within acceptable
limits.
d) Check the level and condition of lubrication oil.
On grease lubricated pumps, check running
hours since last recharge of grease or complete
grease change.
e) Check any auxiliary supplies eg. heating/cooling
(if fitted) are operating correctly.
f) Refer to the manuals of any associated
equipment if routine checks needed.
6.2.2 Periodic Inspection (every 6 Month)
a)
Check foundation bolts for
security of attachment and corrosion.
b) Check pump operation hours to determine if
bearing lubricant shall be changed.
c) The coupling should be checked for correct
alignment and worn driving elements.
Refer to the manuals of any associated
equipment for periodic checks needed.
6.3 Spare parts
6.3.1 Ordering of spares
When ordering spare parts we need the following
information:
1. pump type and pump size
2. serial number of the pump
3. number of the required spare parts
4. reference number and name of the part as listed
in the part list or in the sectional drawing
Example: for HWMA2 pump:
HWMA2, serial number G202222/01
1 piece impeller Pos. 2200
The serial number of each pump is indicated on the
name plate. If the material should be changed from
the original delivered one, additionally indicate the
exact material specification. If ordered impellers shall
have smaller or larger outer diameter, indicate also
with your order. Without a special remark the spare
impellers will be delivered with the diameter of the
original impellers.
If you need the wear rings oversized or undersized,
please indicate, otherwise the wear rings will be
delivered with standard size.
To ensure continuous 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 parts) 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 retreatment of metallic
surfaces (if necessary) with preservative is
recommended at a 6 monthly interval.
