6.2.2 Service parts
The severity of the condition of service, the extent to
which repairs can be carried out in the field, and the
number of units installed will determine, to a great
extent, the minimum number of service parts that
should be carried in stock at the installation site. It is
suggested, as insurance against delays, that service
parts be purchased at the time the pump order is
placed or as soon after receiving the pump as
possible.
A suggested spare parts list (priced if desired) can be
furnished upon request.
6.2.3 Returning parts
All material returned to the factory must have a
returned material (RM) tag attached. Consult the
nearest Flowserve sales office or OEM factory for
shipping instructions and "RM" tags. Unnecessary
delays are avoided when parts or equipment are
returned to the proper factory using the correct
procedure.
a) When contacting the sales office or factory for
return authorization, list the material to be
returned and the reasons for returning it.
b) On receipt of the "RM" tags, be sure to check the
part name, the part number, the quantity of parts
involved, and the serial number of the equipment.
c) The "RM" tag must accompany the material
shipped. Enclose it in the shipping container or
attach it to the part being returned
.
d) In cases where more than one part or box is
returned, individually print or stencil your name,
the part name, and the "RM" tag number on each
part or box. Then attach the "RM" tag to one of
the parts or boxes. This will facilitate quick
identification.
Articles being returned should be carefully packed to
prevent damage from handling or from exposure to
the weather.
6.2.4 Storage of spares
Spares should be stored in a clean dry area away
from vibration. Inspection and re-treatment of
metallic surfaces (if necessary) with preservative is
recommended at every six-months.
