f) Check dirt and dust is removed from areas around
close clearances, bearing housings and motors.
g) Check coupling alignment and re-align if necessary.
Our specialist service personnel can help with
preventative maintenance records and provide
condition monitoring for temperature and vibration to
identify the onset of potential problems.
If any problems are found the following sequence of
actions should take place:
a) Refer to section 7, Faults; causes and remedies,
for fault diagnosis.
b) Ensure equipment complies with the
recommendations in this manual.
c) Contact Flowserve if the problem persists.
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 behaviour. 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 oil lubricant.
e) Check any auxiliary supplies eg heating/cooling
(if fitted) are functioning correctly.
Refer to the manuals of any associated
equipment for routine checks needed.
6.2.2 Periodic inspection (six monthly)
a) Check foundation bolts for
security of attachment and corrosion.
b) Check pump running records for hourly usage to
determine if bearing lubricant requires changing.
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.
6.2.3 Annual
inspection
a) Alignment check
b) Replacement of mechanical seal
c) Inspection of diffuser and impeller wearing rings
d) Inspection of shaft, impeller and diffuser
e) Inspection of casing barrel and discharge head
f) Inspection of balancing drum and ring
g) Inspection of stuffing box and suction head
6.2.4 Two
year inspection
a) Replacement of bearing
b) Inspection of bearing bracket and bearing
housing
6.2.5 Re-lubrication
Lubricant and bearing temperature analysis can be
useful in optimizing lubricant change intervals. In
general however, the following is recommended.
Normal oil change intervals are 4 000 operating hours
or at least every six months. For pumps on hot
service or in severely damp or corrosive atmosphere,
the oil will require changing more frequently.
Lubricant and bearing temperature analysis can be
useful in optimizing lubricant change intervals.
The lubricating oil should be a high quality mineral oil
having foam inhibitors. Synthetic oils may also be
used if checks show that the rubber oil seals will not be
adversely affected. Refer to Section 5.2 Pump
lubricants for oil specification.
The bearing temperature may be allowed to rise to
50 ºC (90 ºF) above ambient, but should not exceed
82 ºC (180 ºF) (API 610 limit). A continuously rising
temperature, or an abrupt rise, indicates a fault.
Pumps that handle high temperature liquids may
require their bearings to be cooled to prevent bearing
temperatures exceeding their limits.
6.2.6 Mechanical
seals
When leakage becomes unacceptable the seal [4200]
will need replacement.
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 – taken from section 8.
4) Part number – taken from section 8.
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
