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. The
correct functioning of the magnetic coupling must
be checked regularly.
c) Check bearing lubricant level, and if the hours run
show a lubricant change is required.
d) Check that the duty condition is in the safe
operating range for the pump.
e) Check vibration, noise level and surface
temperature at the bearings to confirm
satisfactory operation.
f) 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 8,
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 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 ERPN-M pump:
ERPN-M 150-200, serial number G202222/01
1 piece impeller Pos. 425
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.
