Edward’s Stokes 412 mechanical Vacuum Pump (Oil-Sealed Rotary Piston)

NASA's Shared Services Center is soliciting quotes for an Edwards Stokes 412 mechanical vacuum pump (oil-sealed rotary piston) to support operations at the NASA John H. Glenn Research Center. The procurement specifically requires a brand name Edwards Stokes 412 vacuum pump with technical specifications including 300 CFM pumping speed at 60 Hz, ultimate pressure of 3.3 pascals, approximately 1875 pounds weight, 480 VAC three-phase power requirements, water cooling capability, and Class I Division 2 Group B hydrogen-safe rating. The pump will feature an ASA 4-inch gas inlet, 3-inch NPT gas outlet, and nitrogen purge system for hydrogen service applications. NASA will evaluate proposals using the Lowest Price Technically Acceptable (LPTA) method, requiring offerors to be registered in the System for Award Management (SAM) and provide their Cage Code and UEI number. Quote submissions are due by August 29, 2025, at 1:00 p.m. Central Time to the designated contracting officer Laura Quave.

This procurement is set aside exclusively for small businesses under the Total Small Business set-aside program, with no indication of incumbent contractors identified in the documentation. While specific award values are not disclosed in the available documents, the procurement involves a specialized vacuum pump for the SMIRF facility that will replace existing Stokes 200 series roughing pumps currently in operation. The solicitation indicates a 16-week delivery timeline for the specialized equipment, with delivery terms specified as FOB Destination to Cleveland, Ohio. Performance will occur in the United States, specifically at the NASA Glenn Research Center facility, where the pump will integrate with existing infrastructure including structural vacuum lines, gas nitrogen purge systems, and MSA gas detection equipment. The brand name justification emphasizes that alternative vendors would require significant modifications to multiple facility systems, substantially increasing project costs and complexity.
