UNSPSC 47101512: Mixers or agitators

UNSPSC 47101512 Mixers or agitators, a Commodity code, encompasses replacement parts, components, and maintenance services for industrial mixing and aeration equipment at water and wastewater treatment facilities. State and local governments procure under this code to maintain operational aeration systems, replace worn or failed diffusers and drive mechanisms, and source proprietary components for existing treatment infrastructure. Recent solicitations show counties, cities, and special-purpose water authorities acquiring mixer diffuser assemblies, drive shaft units, digester aerator systems, and associated mechanical and control components. Issuing bodies include city water and reclamation departments, county utilities divisions, and regional water treatment authorities, with Florida and Arizona municipal and county jurisdictions appearing frequently in recent posting activity.

Florida and Arizona dominate recent activity under the code. Representative recent opportunities include Collier County's ITB for SCRWTP Lime Softening Improvements—Blend Tank (Solicitation 268683, due July 15, 2026), a $3.29 million construction project encompassing demolition and replacement of a chemical blend tank with new piping, mechanical slide gates, analyzers, and instrumentation; Pinellas County Utilities' ITQ for Invent Mixer Parts & Accessories (26-0647-ITQ, due June 30, 2026), referencing a prior blanket purchase agreement under ITB 22-0279; Marion County's procurement of proprietary Eimco mixer components for the Silver Springs Shores Wastewater Treatment Facility (09SS-148, due May 8, 2026); and the City of Goodyear's IFB for anaerobic digester tank rehabilitation and aeration system replacement at the Corgett Water Reclamation Facility (26-0142, due May 15, 2026). Ware County, Georgia posted a bid for aeration mixing system disc replacement (PE75553NONST2026000000057, due July 6, 2026) including PVC manifold assembly and diffuser installation. Sole-source and continuation procurements are common when equipment is proprietary or system-integrated, as illustrated by Hillsborough County's five-year award to DXP Enterprises for authorized parts and maintenance across multiple original equipment manufacturers ($6.6 million estimated value) and the City of Holly Hill's replacement of a WesTech drive shaft unit ($113,067 total contract value).
