The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 31 units of a rotary pump identified by NSN 7H-4320-014529381. The procurement is based on a sole-source justification, as the Government does not possess the data or rights necessary to purchase or contract repair of this part from alternative sources, making it uneconomical to reverse engineer. This rotary pump is critical for various military applications, and interested parties are encouraged to express their interest and capability to fulfill this requirement within 45 days of the notice, with proposals being considered for award if they meet the necessary qualifications. For further inquiries, interested vendors can contact Jacob Davis at (717) 605-4237 or via email at JACOB.T.DAVIS18.CIV@US.NAVY.MIL.
