To remove badly oxidized grease that refuses to
come off:
a) Support the rotor in a vertical position and
immerse the bearing in hot kerosene or a mixture
of alcohol and light mineral solvent.
b) Gently spin the bearing outer ring.
c) Dry and reflush the bearing with clean light oil.
d) It is important not to under or over grease the
bearings as this will lead to over heating and
premature failure. It is recommended that the
bearings be filled with grease using a suitable
spatula. In addition the housings should be no
more than half filled.
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 gland can be backed off 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.
6.3 Spare parts
6.3.1 Ordering of spares
Flowserve keeps records of all pumps that have been
supplied. When ordering spares the following
information should be quoted.
1) Pump serial number.
2) Pump size.
3) Part name – taken from section 8.
4) Part number – taken from section 8.
5) Number of parts required.
The pump size and serial number are shown on the
pump nameplate.
To ensure continued satisfactory operation,
replacement parts to the original design specification
should be obtained from Flowserve. Any change to
the original design specification (modification or use
of a non-standard part) will invalidate the pump’s
safety certification.
6.3.2 Storage of spares
Spares should be stored in a clean dry area away
from vibration. Inspection and re-treatment of
metallic surfaces (if necessary) with preservative is
recommended at 6 monthly intervals.
