2.4 Storage
Store the pump in a clean and dry
location away from vibration. Leave piping
connection covers in place to keep dirt and other
foreign material out of pump casing. Turn pump at
intervals to prevent brinelling of the bearings and the
seal faces (if fitted) from sticking.
2.4.1 Inspection before storage
a) Inspect the preservative coating/painted surfaces
on the various parts. Touch up the areas, If
necessary.
b) Inspect all covers over pump openings and piping
connections. If found damaged, remove the
covers and inspect interiors of the opening for any
deposits of foreign materials or water.
c) If necessary, clean and preserve the interior parts
as noted above to restore the parts to the "as
shipped" condition. Replace covers and fasten
securely.
2.4.2 Short term storage (less than 6 months)
When it is necessary to store a pump for a short
period of time, place it in a dry location and protect it
thoroughly from moisture.
When protective flanges are bolted to the suction and
discharge nozzles at the factory, they should not be
removed. Protect the bearings and the shaft against
moisture, dirt, or other foreign matter. To prevent
rusting in or seizing, lubricate the unit; see section
5.2, Pump Lubricants . Rotate the pump shaft a
minimum of 5 revolutions every two weeks to keep
the bearings coated with lubricant and to minimize
the effects of brinelling.
Oil lubricated anti-friction bearings are
factory lubricated to prevent rusting for a short period
of time only. Immediately upon receiving equipment,
fill the oil reservoir to the proper level with the proper
lubricant.
2.4.3 Long term storage (6 months and over)
More thorough precautions are required, if
the pump is scheduled to be stored for an extended
period of time. Contact Flowserve before long-term
storage is attempted for specific storage
requirements and warranty information.
The following is a general procedure and could vary
depending on the pump design or specific
application.
The storage area must be clean & dry
location not subject to rapid changes in the
temperature, light or humidity, and relatively free of
ground transmitted vibration due to heavy
construction and/or machinery.
A temperature range of 5 to 50 o C (40 to 120 o F) with
humidity control is recommended.
a) Drain fluid from the pump, rotate the pump rotor
once in the proper direction and blow the liquid
end dry with air.
b) Coat the interior surfaces of the liquid end with
rust inhibitor by brushing, spraying or fogging.
Rotate the pump shaft one turn in the proper
direction while coating.
c) Remove the packing and seal cage from the
stuffing box to prevent corrosion due to
condensation. Coat the interior machined
surfaces of stuffing box with a rust inhibitor. This
step may be omitted if the pumps are stored prior
to initial use.
d) For grease lubricated bearing frames, fill the
cavity between the bearing covers and bearings
with a good grade of NGLI No. 2 lithium base
grease to prevent contamination of the bearings.
Ensure that the bearings are thoroughly packed
with grease. Lubrication quality and quantity
must be checked every six months and replaced
or replenished as necessary. For oil lubricated
bearing frames, upon receipt of the equipment fill
the bearing frame with a good quality R&O oil
capable of providing rust protection to the parts.
Check the oil bi-monthly for signs of water. See
section 5.2, Pump Lubricants.
e) Coat all threaded openings with rust inhibitor and
plug. Coat machined surfaces of exposed
flanges with rust inhibitor and then cover with
fiber board or wood flange covers. Desiccant
bags should be secured to the covers prior to
putting them in place and must not contact metal
surfaces.
f) Coat exposed, unpainted, and machined
surfaces with a rust inhibitor.
g) Cover openings in the stuffing box head between
the casing and bearing frame with plastic, taped
in place, to prevent entrance of contaminants into
the stuffing box and line bearing area.
h) Cover the entire pump with a clear plastic sheet
for protection from dust, dirt moisture, etc. and to
allow for visual inspection. The cover should be
open near the top to allow for ventilation.
