3.6.1.2.5 On board repair parts list. A list of on board repair parts
shall accompany the outline drawings. This list shall be prepared on provision-
ing list forms in accordance with MIL-P-15137. This list shall be furnished
whether or not the parts are required in the pump contract or order. This list
shall not be modified to indicate parts or quantities of parts furnished under
supplementary or separate contracts or orders. The list is intended as a record
of recommendations of the manufacturer and purchaser at the time of equipment
drawing approval. The list of on board repair parts actually purchased shall be
prepared as required by MIL-P-15137 (see 6.5.2).
3.6.1.2.6 Review. Design drawings shall be submitted to the design review
agency for approval (see 6.2.1).
3.6.1.3 Basic design drawings. Basic design drawings covering pumps under
this specification are intended for submittal to the design review agency prior
to and independent of invitations for bids. As such these are different from
design drawings as described in 3.6.1.2. Each drawing may be a range of sizes
of pumps so long as they are of the same basic design.
3.6.1.3.1 Contents of basic design drawings. These drawings shall consist
of small. scale (not necessarily to scale) plan and elevation views showing over-
all dimensions. If the plans cover a family of pump sizes all of the same
design, the dimensions may be tabulated. The range of capacities, pressure and
speeds shall be shown. The main part of this drawing shall be an undimensioned
sectional assembly with complete list of material which shall include every part
required in the pump assembly. If materials of some parts may change with
various pump characteristics or with differing fluids to be pumped, a table shall
be included to show these variations. Alternate subassembly arrangements of
different parts may be included as desired.
3.6.1.3.2 Detail drawings of individual parts are not required in
connection with basic design drawings, but may be included if desired by the
manufacturer for clarification, or to obtain advance approval of the design
review agency.
3.6.1.4 On one of the design delivered drawings described in 3.6.1.2, the
mechanical seal contractor shall identify and certify the following:
Whether or not there is an adhesive or other setting compound
(a)
factory-installed on the elastomer bellows or O-ring that
seals between the mechanical seal and the impeller hub or
shaft sleeve.
The description of any such adhesive or setting compound.
(b)
Any time limit associated with that compound when installed
(c)
on a mechanical seal in stowage and any time limit between
initial wetting of that compound and the final positioning
of the mechanical seal in the pump.
The type and amount of lubricant, if any, to be used to
(d)
facilitate axial positioning of the mechanical seal in the
pump during seal installation. The lubricant shall be
silicone compound in accordance with MIL-S-8660, and all
elastomers, O-rings, or seals shall be compatible with the
silicone compound. The drawing shall require the manufac-
turer to use that lubricant during pump assembly.
