The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanical, is seeking to procure five units of a centrifugal pump (NSN 7H-4320-014985008-A3) under a presolicitation notice. The procurement is limited to a single source due to the government's lack of ownership of the necessary data or rights for alternative sourcing, making it uneconomical to reverse engineer the part. This pump unit is critical for various military applications, and the government intends to solicit and negotiate exclusively with one source under FAR 6.302-1. Interested parties are encouraged to express their interest and capabilities within 45 days of the notice publication, with all proposals considered for determining the potential for competitive procurement. For further inquiries, contact Kathryn E. Shutt at (717) 605-2430 or via email at KATHRYN.SHUTT@NAVY.MIL.
