SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE

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 performing the tasks.

1.7.1 PREPARATION FOR STORAGE

Inspect the preservative coating on the various parts. If necessary, renew the preservative in areas
where it has been rubbed or scraped off. Internal parts of the pump are protected with a petroleum-
based rust preventative. External surfaces of parts that are required to be kept free of paint are coated
with a petroleum-based rust preventative.

Inspect all painted surfaces. If necessary, touch-up areas where paint has been chipped or scraped.
External surfaces are usually painted with a paint that combines a primer with a finish coat. See the
contract specification for any non-standard paint requirements, or contact your nearest Flowserve
office.

Inspect all covers over pump openings and piping connections. If the covers or seals for the covers
are loose or damaged, remove them and visually inspect the accessible interior areas for accumulation
of foreign matter and/or water. If necessary, clean and recoat the interior parts with preservative
and/or paint to restore the parts to the as-shipped condition. Install or replace the covers and fasten
securely.

If the pump was shipped in a sealed plastic covering, then the covering should be reinstalled prior to
placing the pump in storage.

1.7.2 STORAGE AREA

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
must be stored indoors. When stored outdoors the pump and its components should be protected from
dirt, dust, rain, snow, or other unfavorable 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.

When selecting a storage area, it should be taken into consideration that the deterioration of the
equipment and the expenses involved in restoring the equipment at the time of installation will be
proportionate to the class of storage provided.

1.7.3 INSPECTION AND MAINTENANCE

The responsibility for setting up an inspection schedule rests with the purchaser and will be
dependent upon the class of storage provided. Initially, inspection would occur weekly. Then,
depending upon the conditions encountered in the inspection reports, inspection should continue
weekly, monthly, or quarterly.

Each inspection should include the following steps, as a minimum:

1. Check that the pump supports are firmly in place.
