3.3.1 Material deterioration prevention and control. The pump unit shall be fabricated from
compatible materials, inherently corrosion resistant or treated to provide protection against the
various forms of corrosion and deterioration that may be encountered in any of the applicable
operating and storage environments to which the unit may be exposed.
3.3.2 Dissimilar metals. Dissimilar metals shall not be used in intimate contact with each
other unless protected against galvanic corrosion. Dissimilar metals and methods of protection
are defined and detailed in MIL-STD-889.
3.3.3 Identification of materials and finishes. The contractor shall identify the specific
material, material finish or treatment for use with each component and subcomponent, and shall
make this information available upon request to the contracting officer or designated
representative.
3.3.4 Recovered materials. For the purpose of this requirement, recovered materials are
those materials which have been collected from solid waste and reprocessed to become a source
of raw materials, as distinguished from virgin raw materials. The components, pieces and parts
incorporated in the pump unit may be newly fabricated from recovered materials to the
maximum extent practicable, provided the unit produced meets all other requirements of this
specification. Used, rebuilt or remanufactured components, pieces and parts shall not be
incorporated in the pump unit.
3.4 Design. The pump unit shall be designed and constructed in accordance with all
applicable requirements and provisions of API Std 610 except for 3,000 hours of uninterrupted
operation.
3.5 Interchangeability. All pump units furnished with similar options under a specific
contract shall be identical, to the extent necessary, to ensure interchangeability of component
parts, assemblies, accessories, and spare parts.
3.6 Operating conditions.
3.6.1 Operating temperature. The pump unit shall perform as specified herein in any
ambient temperature from -25 to +135 F.
3.6.2 Altitude. The pump unit shall perform at any altitude from sea level to 6,000 feet
above sea level at 100 F, without significant loss (not to exceed 10 percent) of capacity and
head.
3.6.3 Storage temperature. The pump unit shall not be damaged by storage in any ambient
temperature from -60 to +155 F.
3.7 Safety. All shafts or rotating parts of the pump unit shall be guarded when such parts are
exposed to contact with personnel or otherwise create a hazard. All hot surfaces of the
equipment, including exhaust pipes exposed to contact with personnel or which create a fire
hazard, shall be fully guarded or insulated. Fuel tanks shall be located in a manner which will
not allow spills or overflows to run onto the engine, exhaust, or electrical equipment. Adequate
shielding may be used to attain the same result. Exhausts or discharges from the equipment shall
