Before working on the pump, take measures to

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) Gland packings must be adjusted correctly to

give visible leakage and concentric alignment of

the gland follower to prevent excessive

temperature of the packing or follower.

c) Check for any leaks from gaskets and seals.

The correct functioning of the shaft seal must be

checked regularly.

d) Check bearing lubricant level, and if the hours

run show a lubricant change is required.

e) Check that the duty condition is in the safe

operating range for the pump.

f) Check vibration, noise level and surface

temperature at the bearings to confirm

satisfactory operation.

g) Check dirt and dust is removed from areas

around close clearances, bearing housings and

motors.

h) 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. 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 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

Re-lubrication

Lubricant and bearing temperature analysis can be

useful in optimizing lubricant change intervals. In

general however, the following is recommended.


6.2.3.1 Oil lubrication

Maintaining the correct oil level is very

important.

If the pump is supplied with a constant level oiler the

oil level will be automatically maintained and as long

as oil is visible in the glass bottle there is no need to

refill. If however a sight glass has been fitted then

regular checks should be made to ensure the level is

maintained at the centre of the glass window.

Refer to section 5.1.1 for methods of oil fill, section

5.2.1 for oil grade recommendations and 5.2.3 for the

schedule and temperature limits.
