About this file
This Statement of Work (SOW) details NASA's procurement requirements for a vacuum pumping system for the Lunar Environment Structural Test Rig #2 at NASA Glenn Research Center. The procurement includes specific Edwards-brand vacuum pumping equipment, including the Next85D Pump with 4.5-inch inlet and nXDS6i Scroll Pump, along with 24 auxiliary hardware components necessary for a complete end-to-end vacuum handling system supporting Artemis mission critical objectives.
The SOW specifies precise technical requirements, including a vacuum operating pressure of 1*10^-6 Torr, ambient temperature operation, and delivery to NASA Glenn Research Center in Cleveland, OH. Vendor proposals must include fabrication and delivery schedules, shipping costs, and a list of deliverables. A special note emphasizes that multiple line items must be brand-name Edwards products. The procurement is set aside for small businesses, with a warranty requirement of at least 12 months on parts from the time of delivery.
