1.19 Long term storage
General
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 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.
1.20 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.
1.21 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 11/4 turns each week during
the storage period and any other periods of stand by.
When selecting a storage area the following should be taken into
consideration.
1.
The deterioration of the equipment will be proportionate to the class of storage provided.
2.
The expenses involved in restoring the equipment at time of installation will be proportionate
to the class of storage provided.
