Brand Name Solicitation: Deicer Pump, Gorman-Rupp Rotary Gear Pump, Model: GHS3RR3-B

The Department of the Army Michigan Army National Guard is seeking to procure a specific Gorman-Rupp Rotary Gear Pump, model GHS3RR3-B, for deicer application at Selfridge Air National Guard Base. This brand name solicitation (W50S8525QA045) requires a cast iron pump with 3" suction and discharge, 125# ANSI flanges, ductile iron rotor, and Carbon/Buna-N mechanical seal, close-coupled to a 7.5HP motor and mounted on a fabricated steel base plate with OSHA-rated coupling guard. The procurement is justified as a sole-source requirement due to the pump's unique internal coating and gear configuration essential for compatibility with the existing pump system being replaced. The solicitation follows a firm fixed price structure under a Request for Quote procurement method, with proposals due by July 31, 2025, at 2:00 PM. Questions and answers are being updated periodically and posted on both Unison Global Marketplace and Sam.gov where the complete solicitation and attachments are available.

This procurement is set aside as a Total Small Business opportunity, specifically designated as a Women-Owned Small Business (WOSB) set-aside under NAICS code 333914 with a size standard of 750 employees. No incumbent contractor information is provided in the available documentation, and the total estimated contract value has been redacted from the justification documents. The contract requires delivery of the single pump unit within 180 calendar days from the award receipt date to Building 191 at Selfridge Air National Guard Base in Harrison Township, Michigan. The contracting officer Austin Parks can be reached at 586-239-5235 or austin.parks.8@us.af.mil for inquiries. While this is a brand name procurement for a specific Gorman-Rupp model, the justification document notes that the pump can be obtained from multiple suppliers and distributors, potentially allowing for competition among authorized dealers.
