Refer to the manuals of any associated
equipment for periodic checks needed.
6.1.3 Mechanical seals
No adjustment is possible. When leakage reaches an
unacceptable level the seal will need replacement.
6.1.4 Gland packing
The stuffing box split gland can be completely
removed for re-packing or to enable the addition of

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.
