Refer to section 5.1.1 for methods of oil fill, section
5.2.1 for oil grade recommendations and 5.2.4 for the
schedule and temperature limits.
6.2.4 Mechanical seals
No adjustment is possible. When leakage reaches an
unacceptable level the seal will need replacement.
6.2.5 Gland packing
The stuffing box split gland can be completely
removed for re-packing or to enable the addition of
extra rings of packing.
The stuffing box is normally supplied with a lantern
ring to enable a clean or pressurised flush to the
centre of the packing. If not required, this can be
replaced by an extra 2 rings of packing.
There must always be a small leakage, normally a
minimum of 120 drops per minute to atmosphere to
lubricate and cool the packing is required.
