pump performance curve to determine exact
requirements particularly if flow has changed.
If in doubt please consult your nearest Flowserve
office for advice and details of the minimum
allowable margin for your application.

Flow must not fall outside the minimum and
maximum continuous safe flow shown on the pump
performance curve and or data sheet.
6 MAINTENANCE
6.1 General
It is the plant operator's responsibility to
ensure that all maintenance, inspection and
assembly work is carried out by authorized and
qualified personnel who have adequately
familiarized themselves with the subject matter by
studying this manual in detail. (See also section
1.6.2.)
Any work on the machine must be performed when
it is at a standstill. It is imperative that the
procedure for shutting down the machine is
followed
On completion of work all guards and safety
devices must be re-installed and made operative
again.
Before restarting the machine, the relevant
instructions listed in Section 5, Commissioning,
start-up, operation and shut down must be
observed.
Oil and grease leaks may make the ground
slippery. Machine maintenance must always
begin and finish by cleaning the ground and the
exterior of the machine.
If platforms, stairs and guard rails are required for
maintenance, they must be placed for easy access
to areas where maintenance and inspection are to
be carried out. The positioning of these
accessories must not limit access or hinder the
lifting of the part to be serviced.
When air or compressed inert gas is used in the
maintenance process, the operator and anyone in
the vicinity must be careful and have the
appropriate protection.
Do not spray air or compressed inert gas on skin.
Do not direct an air or gas jet towards other people.
Never use air or compressed inert gas to clean
clothes.
Before working on the pump, take measures to
prevent an uncontrolled start. Put a warning tag 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 tag
on the fuse box or main switch with the words:
"Machine under repair: do not connect".
Never clean equipment with flammable solvents or
carbon tetrachloride. Protect yourself against toxic
fumes when using cleaning agents.
When operating with CHARGABLE LIQUIDS
with conductivities of <10-8 S/m, inert gases (e.g.
nitrogen) must be used to flush the pump. Before
removal of the pump it is recommended to wait one
hour to allow static peak charges to be eliminated.
ALWAYS make certain that no
toxic or flammable fumes / vapors remain in the
pump casing [1100] or surrounding area.
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) If the pump is long coupled, bearing isolators
and mechanical seals must be adjusted
correctly to prevent leakage. Any fluid leakage
from the pump is unusual.
c) Check for any leaks from gaskets and seals (if
present). Pump is designed to be leak-free, any
leak is abnormal. If a mechanical seal is
present, the correct functioning of the shaft
seal must be checked regularly.
d) If the pump is long coupled, check bearing
lubricant level, and if the hours run shows 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 to confirm satisfactory operation.
g) Check dirt and dust is removed from areas
around close clearances, bearing housings (if
present) and motors.
