Justification for Sole Source

This is a Justification for Sole Source (J&A) document supporting a contract award in the $15,000–$350,000 range under Federal Acquisition Regulation (FAR) 13.106-1(b). The document is issued by DLA Weapons Support Puget Sound dated October 16, 2025, and justifies a sole-source procurement for replacement parts (Document 6302-1351).

The required item is a SHAEFFLER Pc-8A pump assembly with part number B-0235-01, detail drawing NA1940, at an estimated cost per unit with a Required Delivery Date (RDD) of 02/02. The sole-source manufacturer is Buffalo Pumps, located at 874 Oliver Street, North Tonawanda, NY, 14120. The original manufacturer contact is Stephen Brown at (716) 693-1850. The manufacturers' dealer/representative is ECI Defense Group / Josh Haney, located at 970 Progress Center Avenue, Lawrenceville, GA 30043, phone (770) 727-6229.

The justification asserts that these replacement sleeves for the Reactor Plant Sea Water Cooler Circulating Pump manufactured by Buffalo Pumps are integral to proper functioning of the parent component and are the only parts meeting the form, fit, and functional requirements. The sleeves must fit the shaft and are manufactured by Buffalo Pumps, which owns proprietary drawings for both the shaft and sleeves. Buffalo Pumps' detailed drawings for sleeve manufacture represent proprietary data that limits competition. The document certifies that there are no substitutes available and that this is a direct replacement part for existing brand-name equipment.
