2.4 Storage
Store the pump in a clean, dry
location away from vibration. Leave flange covers in
place to keep dirt and other foreign material out of
pump casing.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.
2.4.1 Short term storage and packaging
Normal packaging is designed to protect the pump
and parts during shipment and for dry, indoor
storage for up to six months or less. The following is
an overview of our normal packaging:
• All loose unmounted items are packaged in a
water proof plastic bag or box.
• Inner surfaces of the bearing housing, shaft (area
through bearing housing) and bearings are coated
with Cortec VCI-329 rust inhibitor, or equal.
• Regreaseable bearings in the pump are packed
with Keystone 81-EP-2 lithium-based grease for
the thrust bearing (and the line shaft bearings
when grease lubrication is used).
• The internal surfaces of ferrous casings, covers,
flange faces, and the impeller surface are
sprayed with Cortec VCI-389, or equal
• Exposed shafts are taped with Polywrap
• Flange covers are secured to both the suction
and discharge flanges
• In some cases with assemblies ordered with
external piping, components may be
disassembled for shipment
• The pump must be stored in a covered, dry
location
• Every three months the pump shaft should be
rotated several revolutions to prevent brinelling
of the thrust bearing and sticking of the seal
faces (if fitted).
2.4.2 Long term storage and packaging
Long term storage is defined as more than six
months, but less than 12 months. The procedure
Flowserve follows for long term storage of pumps is
given below. These procedures are in addition to
the short term procedure.
• Each assembly is hermetically (heat) sealed
from the atmosphere by means of tack wrap
sheeting and rubber bushings (mounting holes)
• Desiccant bags are placed inside the tack
wrapped packaging
• A solid wood box is used to cover the assembly
This packaging will provide protection for up to
twelve months from humidity, salt laden air, dust etc.
After unpacking, protection will be the responsibility of
the user. Addition of oil to the bearing housing will
remove the inhibitor. If units are to be idle for extended
periods after addition of lubricants, inhibitor oils and
greases should be used.
2.5 Recycling and end of product life
At the end of the service life of the product or its
parts, the relevant materials and parts should be
recycled or disposed of using an environmentally
acceptable method and in accordance with local
regulations. If the product contains substances that
are harmful to the environment, these should be
removed and disposed of in accordance with current
local regulations. This also includes the liquids
and/or gases that may be used in the "seal system"
or other utilities.
Make sure that hazardous substances are
disposed of safely and that the correct personal
protective equipment is used. The safety
specifications must be in accordance with the current
local regulations at all times.
