UNSPSC 31411701: Pusher mechanical seal

A mechanical seal utilizing a dynamic secondary seal or o-ring that is responsible for sealing the fluid path between the pump shaft and the inside diameter of the rotating seal face.

UNSPSC 31411701 Pusher mechanical seal is a Commodity code that state and local governments procure primarily as a component within broader material supply agreements for infrastructure maintenance and fleet management, though recent solicitation activity shows limited direct procurement of the product in isolation. The code sees activity from county purchasing departments, state transportation agencies, school districts, and municipal fleet services divisions, typically through RFQ, IFB, and supply-agreement vehicles. The Maine Department of Transportation issued RFQ 17A 260427-275 in May 2026 for bridge joint seals and related materials—a $100,000-plus procurement that encompasses compression seals, silicone-coated foam seals, gland seals, lubricants, and supporting materials delivered to nine MaineDOT locations across five regions; the Sarasota County School Board issued Bid #26-0124 in January 2026 establishing a one-year automotive and light truck repair parts supply agreement with percentage discounts off manufacturer list prices across 19 specified vendors and allowance for additional manufacturers. Brevard County, Florida and the City of Atlanta similarly issued procurement notices for fleet maintenance and heavy-duty equipment repair services and parts supply, though those solicitations address broader inventory management and trailer-related components rather than mechanical seals per se.

Recent procurement activity concentrates in Florida (Brevard County, Sarasota County School Board) and Maine (MDOT), with secondary activity in Georgia (City of Atlanta) and multi-jurisdictional cooperative purchasing frameworks. The Maine RFQ, due June 1, 2026, represents the most directly relevant opportunity, specifying 76 line items across multiple seal product categories with delivery to multiple regions and a Master Agreement term extending through June 30, 2031 with optional extensions. The Sarasota County school procurement (due February 12, 2026) and Brevard County fleet services bid establish recurring supply relationships with cost-plus or discount-off-list pricing models. No incumbent vendors or award values are disclosed in available materials. The code shows modest recent activity—most opportunities tag mechanical seals or related products as line items within larger materials and parts supply agreements rather than standalone procurements, suggesting that pursuit strategy should emphasize joint-sealing and bridge-maintenance supply partnerships or fleet-parts distribution relationships where mechanical seals serve as one component within a broader catalog.
