The pump size and serial number are shown on the
pump nameplate.
To ensure continued satisfactory operation,
replacement parts to the original design specification
should be obtained from Flowserve.
Any change to the original design specification
(modification or use of a non-standard part) will
invalidate the pump’s safety certification.
6.3.2 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 6 monthly intervals.
For large quantities of Gearex pumps, it is advisable
to refer to Marketing Department, Brantford, Ontario,
Canada, giving full detail of quantities, sizes and
metallurgy.
The severity of the conditions 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 spare parts which
should be carried in stock at the site of the
installation.
6.3.3 Returning parts
All materials for return to the factory must have a
Return Material Authorization. Consult the nearest
District Office or Factory Customer Service Dept.
(CS) for shipping instructions and a 'Return Material
Tag’.
Unnecessary delays are avoided when parts or
equipment are returned to the factory using the
correct procedure.
a) On receipt of the Return Material Number, mark
or tag the material to be returned with this
number. In cases where more than one part or
box is returned, print or stencil your company
name and the Return Material Number on each
part or box. This will facilitate quick identification.
Articles being returned should be carefully
packed to prevent damage from handling or from
exposure to weather.
b) Contact your nearest District Office, listing
material to be returned and the reasons for
returning it. Make sure you give the name of the
part and the part number involved and the serial
number of the equipment. Give the method and
date of shipment. This will notify the factory that
material is enroute.
c) Do not return parts without authorization.
