Three Vacuum Pumps for A1

NASA's Shared Services Center is seeking to procure three MD Kinney MB200-KD30-M4A0 Vacuum Pump Packages equipped with Class 1, Division 2, Group B motors and solenoids through a sole source acquisition. The agency has determined that International Manufacturers Representatives, Inc. is the only viable vendor capable of providing these pumps due to specific technical and operational compatibility requirements with existing barges at the facility. The government intends to award the contract under FAR 12.102(a) using commercial item procedures, with NAICS Code 333914 (Measuring, Dispensing, and Other Pumping Equipment Manufacturing) applied to this procurement. Interested organizations may submit written capabilities and qualifications to Procurement Specialist Shanna Patterson (Shanna.L.Patterson@nasa.gov) by 7:00 a.m. Central Standard Time on April 23, 2026, with submissions evaluated solely to determine whether to proceed competitively or as sole source at the government's discretion. The solicitation was posted on April 21, 2026, with the same date serving as the response deadline, providing potential offerors with minimal time to prepare submissions.

This procurement carries no set-aside designation and names International Manufacturers Representatives, Inc., located at 10040 Mammoth Avenue, Baton Rouge, Louisiana, as the intended sole source awardee. The specific cost estimate has been redacted from available documentation, but the acquisition involves the procurement and delivery of three vacuum pump units with an estimated 12-week lead time from award. The government justified the sole source determination based on the requirement for design compatibility and interchangeability with existing systems, as alternative vendors would necessitate design modifications, piping changes, additional spare parts inventory, and recurring engineering modifications. Performance will be located at NASA's John C. Stennis Space Center in Mississippi, where the vacuum pumps will be installed on the Liquid Oxygen and Liquid Hydrogen barges at the test complex. NASA FAR Supplement Clause 1852.215-84 (Ombudsman) applies to this acquisition.
