Goulds Pumps 3410 - IOM - Manual (Page 36)

INITIAL INSPECTION AFTER
STARTING
Packed Box
With pump running at rated speed, stuffing box gland can
be adjusted. Draw gland nuts up evenly and only 1/6 of a
turn at a time, allowing sufficient time between adjustments
for packing to adjust itself and effect on leakage to be
observed. If any sign of heating is evident, shut down the
pump and allow the box to cool. Several starts may be
necessary before box runs cool. Do not back off the gland
nuts on a hot box as this will usually result in leaking
between the outer edge of the packing and the stuffing box
bore. Remember that it takes newly-installed packing some
time to run in and that during this period, frequent attention
and careful adjustments are necessary.
Mechanical Seal
The mechanical seal was adjusted at the factory. If the seal
leaks slightly when the pump is first started, a few hours
run-in will allow the seal to adjust itself.
$
CAUTION
Never run seal dry. Make sure flush cooling lines, if
any, are operating properly.
SHUTDOWN
1. Slowly close discharge valve.
2. Shut down and lock driver to prevent accidental
rotation.
s
! WARNING
When handling hazardous and/or toxic fluids, proper
personal protective equipment should be worn. If
pump is being drained, precautions must be taken to
prevent physical injury. Pumpage must be handled
and disposed of in conformance with applicable
environmental regulations.
FINAL ALIGNMENT
!
Alignment procedures must be followed to prevent
unintended contact of rotating parts. Follow
coupling manufacturer's coupling installation and
operation procedures.
1. Run the unit under actual operating conditions for a
sufficient length of time to bring the pump and driver
and associated system up to operating temperature.
2. Remove coupling guard.
3. Check alignment while unit is still hot per alignment
procedure in the Installation Section.
4. Reinstall coupling guard.
