The grease used in factory for first filling is:

SHELL ALVANIA R2

 

Its equivalents: MOBIL

: Mobilux EP 2,

TOTAL

: Multis 2,

ELF

: ELF MULTI

6.2.2 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)Pump fitted with a stuffing box: leakage of 20 drops per minute.

d)Pump fitted with a mechanical seal: no leakage.

e)Check the level and condition of oil lubricant. On grease lubricated pumps, check running hours since last recharge of grease or complete grease change.

6.2.3 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.

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 Gland packing6.2.5.1 Pump fitted with a packed gland

A well run in and correctly adjusted packing gland requires little maintenance.

If, after some time, the leakage becomes too great, the gland should be tightened again in order to return these to a normal level.

If re-tightening is not possible, new packing must be installed

6.2.5.2 Gland packing inspection and removal

a)Remove the shield guards.

b)Slide back the gland.

c)Remove the packing rings with an extractor designed for this purpose (including the lantern ring if it exists; note its position and its direction of rotation).

d)Inspect the state of the sleeve surface; the presence of many marked grooves will indicate that it must be replaced.

e)Carefully clean the different pieces of the packing gland.

6.2.5.3 Gland packing fitting

If the packing is supplied as cord the packing must be cut so that the external diameter is lightly tightened and there is an initial gap between the sleeve and the packing ring.

For that purpose, wind the packing helically around the shaft sleeve or a chuck of the same diameter. (Take precautions to avoid damaging sleeve)
