prevent an uncontrolled start. Put a warning board
on the starting device with the words:
"Machine under repair: do not start".
With electric drive equipment, lock the main switch
open and withdraw any fuses. Put a warning board
on the fuse box or main switch with the words:
"Machine under repair: do not connect".
Never clean equipment with inflammable solvents
or carbon tetrachloride. Protect yourself against
toxic fumes when using cleaning agents.
6.2 Maintenance schedule
It is recommended that a maintenance plan
and schedule is adopted, in line with these User
Instructions, to include the following:
a) Any auxiliary systems installed must be
monitored, if necessary, to ensure they function
correctly.
b) Check for any leaks from gaskets and seals.
c) Check bearing lubricant level, and if the hours
run show a lubricant change is required.
d) Check vibration, noise level and surface
temperature at the bearings to confirm
satisfactory operation.
e) Check dirt and dust is removed from areas
around close clearances, bearing housings and
motors.
f) 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 the level and condition of oil lubricant.
c) 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) 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
Re-lubrication
Lubricant and bearing temperature analysis can be
useful in optimizing lubricant change intervals. In
general however, the following is recommended.
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 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.
