UNSPSC 47101512: Mixers or agitators

UNSPSC 47101512 Mixers or agitators (Commodity) covers replacement drive shafts, mixer parts and accessories, and aeration system components that state and local water and wastewater treatment facilities procure to maintain or upgrade existing equipment. The code encompasses both proprietary parts for installed systems—such as WesTech dual-shaft drives and Eimco mixer components—and generic aeration disc assemblies, with work ranging from sole-source parts procurement to turnkey installation services at operating treatment plants. Issuing bodies are primarily municipal water utilities and county water/wastewater authorities, including the City of Holly Hill, Collier County, Pinellas County Utilities, Marion County, and Ware County in Georgia; these jurisdictions solicit under the code repeatedly as aging treatment infrastructure requires component replacement or retrofit.
