About this file
This document is a Statement of Work (SOW) for a Lunar Environment Structural Test Rig Vacuum Pumping System procurement for NASA Glenn Research Center, dated May 8, 2025. The solicitation requires a comprehensive vacuum pumping system centered on specific Edwards pumping equipment, including one Edwards Next85D Pump with a 4.5-inch ConFlat Flange Inlet and one Edwards Vacuum nXDS6i Scroll Pump, along with 24 additional auxiliary hardware components such as power cables, controllers, cooling units, vacuum gauges, and various fittings and adapters.
The system is designed to support mission-critical Artemis ESDMD EHP objectives through cryogenic structural testing, with a required vacuum operating pressure of 1x10^-6 Torr or better at ambient temperature. The vendor must deliver the system to NASA Glenn Research Center in Cleveland, OH, with a manufacturer's warranty of at least 12 months. The procurement is set aside for small businesses, and the vendor's proposal must include a fabrication and delivery schedule, shipping costs, a list of deliverables, and any exceptions to the government requirements. The total system is intended to provide an end-to-end vacuum handling solution for the Lunar Environment Structural Test Rig #2.
