SSJ REVISED1_Redacted (1).pdf

This is a Sole Source Justification (NTE SAT) filed by Naval Supply and Logistics Centers (NAVSUP) Fleet Logistics Centers for a commercial purchase restriction under FAR 12.102(a).

The procurement seeks replacement parts to rebuild central seawater cooling pumps for AKE-class naval vessels: Part No. 5363A Impeller (QTY 1) and Part No. 5363B Casing Rings (QTY 2). The required delivery date is September 30, 2026. The purchase request number is listed as TBD, with the estimated cost redacted. Competition is restricted exclusively to Sims Pump and Valve Co., Inc. (CAGE 78314), the Original Equipment Manufacturer of the installed pumps. The justification establishes that these Central Seawater Cooling Centrifugal Pumps are designated Critical Safety Items essential to Main Propulsion Diesel Engine operation and overall vessel safety aboard AKE-class vessels. The document asserts that failure or malfunction could result in equipment damage, mission degradation, or personnel safety hazards. Only OEM parts are acceptable due to strict compatibility requirements with existing pump assemblies; any deviation from original design specifications introduces unacceptable risk to system integrity and performance. Sims Pump Valve Co. maintains proprietary design specifications and manufacturing tolerances necessary to produce compliant components and does not maintain authorized distributors, requiring direct procurement from the OEM. The justification notes that Military Sealift Command lacks the technical data package, manufacturing drawings, and performance validation criteria needed to evaluate alternative or non-OEM components, and no engineering analysis or testing has been conducted regarding the impact of substituting non-OEM parts in these critical systems.
