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 representing specialized rotating equipment components that state and local governments procure for water treatment, wastewater, pump, and industrial maintenance. State and local buyers acquire these seals as replacement parts and repair consumables for centrifugal and positive-displacement pumps used in municipal water systems, environmental operations, and facility infrastructure. The issuing bodies span cities, counties, state departments of transportation, and regional authorities responsible for water delivery and treatment infrastructure. The scope includes pusher seals themselves along with associated mechanical seal assemblies, repair kits, and related bearing and seal cartridge components needed to maintain pumping equipment in operational condition.

Recent activity shows limited documented opportunities under this specific code. The City of Port Orange, Florida issued a sole-source procurement notice (SS2620CW, due September 16, 2026) for NOV Chemineer Moyno pump products and repair services valued at approximately $500,000 annually, seeking verification whether competing authorized dealers could supply the equipment Carl Eric Johnson, Inc. currently provides across Florida, Alabama, Georgia, and Tennessee. The State of Maine Department of Administrative and Financial Services issued an RFQ (17A 260427-275, due June 1, 2026) on behalf of the Maine Department of Transportation for a Master Agreement covering bridge joint seals and related materials with delivery to nine MaineDOT locations across five regions, though this solicitation addresses joint seals rather than pusher mechanical seals per se. Florida and Maine represent the only states with documented recent state-local procurement activity tied to this code.
