4) Check hold down bolt positions on the graph or
otherwise determine the amount of shims to be
added or subtracted for the vertical correction,
and the movement required for the horizontal
correction, if either exceeds maximums. If
maximums are exceeded in this hot alignment:
a) Allow units to cool down
b) Complete steps 18a through 18e, 19 and 20
under Cold Alignment (section 4.8.3).
c) Repeat Hot Alignment (section 4.8.4)
procedure until TIR is within specifications.
5) Dowel driver feet that are nearest coupling, and
pump feet that are nearest coupling if pump is
equipped with aligning pin and key.

Protection systems
The following protection systems are
recommended particularly if the pump is installed in
a potentially explosive area or is handling a
hazardous liquid. If in doubt consult Flowserve.
If there is any possibility of the system allowing the
pump to run against a closed valve or below
minimum continuous safe flow, a protection device
should be installed to ensure the temperature of the
liquid does not rise to an unsafe level.
If there are any circumstances in which the system
can allow the pump to run dry, or start up empty, a
power monitor should be fitted to stop the pump or
prevent it from being started. This is particularly
relevant if the pump is handling a flammable liquid.

COMMISSIONING STARTUP,
OPERATION AND SHUTDOWN
5.1
Precommissioning procedure
Before being put on line (i.e., started), the pump, the
driver, and any auxiliary systems require an external
inspection for operational readiness. Both the lube
oil and seal flushing systems require flushing. A new
pump or an old pump that has been preserved by
the plant requires depreservation before liquid is
introduced for the first time. And a pump that pumps
a liquid at a temperature above 121°C (250°F) must
undergo a warm-up prior to operation to prevent
thermal distortion and the consequent rubbing or
breaking of parts. The following paragraphs are
given in the sequence recommended for start-up.
5.1.1 Readying and servicing driver
Before operating the driver, gear, or any other
auxiliary equipment, perform the operational
readiness and servicing checks that are
recommended in their manufacturer's operating and
maintenance instructions (see Section 10 or your
plant's data file for information).
5.1.2 Readying and servicing pump and
auxiliary systems
Before starting the pump or an auxiliary system,
perform the readying and servicing tasks in the
given sequence for the pump and any auxiliary
systems installed.
5.1.2.1 Initial steps in preparing brand-new or
factory-overhauled pump and auxiliary
systems for operation
Proceed as follows:
1) Comply with requirements under section 2.4.3
2) Flush lube oil system piping and seal flushing
piping as required in section 5.2.4.
3) Make certain that lube oil system piping and seal
flushing piping are connected, secured, and
ready for operation.
4) Check all auxiliary components such as
indicators, filters, heat exchangers, control
panels, terminal boxes and housings, motors,
auxiliary pumps, and valves for damage,
installation, cleanliness, and security.
5) Ensure:
That seal units are installed, and
That bearings are assembled.
5.1.2.2 Initial steps in preparing for operation of
old pump that has been off-line for
extended period
Make certain:
1) That the pump is depreserved in accordance
with procedures which that assure removal of
any preservative compound which is
incompatible with, or will impede, pumpage (or
flow).
2) That any rust and corrosion will not affect
function of internal assembly, bearings, and
seals.
3) That seal flushing piping is free of rust, corrosion,
and preservative compound.
4) That lube oil piping and reservoir are free of
sludge, foreign materials such as metal particles
and welding beads, moisture, and other
contaminant.
5) That lube oil reservoir is thoroughly cleaned with
solvent such as kerosene or naphtha and wiped
dry with clean lint free rags.
5.1.2.3 Following fabrication and rework of
piping
Flush applicable system as required in section 4.6.3
and section 5.2.4 whenever piping is reworked, a
