2.4 Storage
Store the pump in a clean, 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.
Electric Motors (Pump Driver) should not be stored
in damp places without special protection (Refer to
Motor manufacturers instructions).
The pump may be stored as above for up to 6
months.
2.4.1 Long term storage
During extended periods of storage prior to
installation, precautions must be taken to protect
the pump from deterioration. The various parts of
the pump are protected prior to shipment by
applying varying grades of preservative to the
parts. However, during shipment and handling the
preservatives are subjected to conditions that can
cause their removal. Also, during extended
periods of time the preservatives may deteriorate.
The listed procedures (2.4.1.1 to 2.4.1.5) should
be followed to prevent deterioration of the pump
during the extended storage period. These
procedures may also be supplemented by the
experience of the person(s) performing the tasks.
2.4.1.1 Inspection upon arrival
When the pump is received it should be inspected
for damage or other signs of rough handling. If any
damage is found it should be reported to the
carrier immediately. Inspect the preservative
coating on various parts. If necessary, renew
preservative in areas where it has been rubbed or
scraped.
Inspect all painted surfaces. If necessary, touch up
the areas where paint has been chipped or
scraped.
Inspect all covers over pump openings and piping
connections. If covers or seals for the covers are
damaged or loose, they are to be removed, and a
visual inspection made of the accessible interior
areas for accumulation of foreign materials or
water. If necessary, clean and preserve the interior
parts as noted above to restore the parts to the "as
shipped" condition. Install or replace covers and
fasten securely.
2.4.1.2 Storage
If at all possible, the pump and its
component parts should be stored indoors where
they will be protected from the elements. In no
case should any pump element be subjected to
extended periods of submergence or wetting prior
to start up. If it is not possible to store the pump
and its components indoors, precautions must be
taken to protect them from the elements.
Regardless of whether storage is indoors or
outside, the storage area should be vibration free.
All boxes marked for indoor storage should be
stored indoors. When stored outdoors the pump
and its components should be protected from dirt,
dust, rain, snow, or other unfavourable conditions
by heavy plastic sheets, canvas, waterproof burlap
or other suitable coverings.
All equipment must be placed upon skids or blocks
to prevent contact with the ground and surface
contaminants. Equipment must be adequately
supported to prevent distortion and bending.
The pump shaft should be rotated, in the direction
of rotation, at least 1 and 1/4 turns each week
during the storage period and any other periods of
standby.
When selecting a storage area the following
should be taken into consideration.
a) The deterioration of the equipment will be
proportionate to the class of storage provided.
b) The expenses involved in restoring the
equipment at time of installation will be
proportionate to the class of storage provided.
2.4.1.3 Inspection and maintenance
The stored equipment has to be placed on a
periodic inspection schedule by the purchaser.
The responsibility for setting up an inspection
schedule rests with the purchaser and will be
dependent upon the class of storage provided. It
would be expected initially, inspection would occur
weekly, then depending upon the inspection
reports being favorable or unfavorable, inspection
would continue weekly, monthly, or quarterly, as
may be determined.
Each inspection should consist of a general
surface inspection to assure that:
a) Pump supports are firmly in place.
b) Pump covers over openings are firmly in
place.
c) Pump coverings, plastic or tarps are firmly in
place. Any holes or tears must be repaired to
prevent entrance of dirt or water.
d) Pump covers are periodically removed from
openings and interior accessible areas
inspected. If surface rusting has occurred,
clean or coat with preservative.
e) If rusting occurs on exterior surfaces clean and
repaint or coat with preservative.
f) Check individually wrapped parts for signs of
deterioration. If necessary, renew preservative
and wrapping.
