UNSPSC 31121717: Composite centrifugal machined castings

UNSPSC 31121717 Composite centrifugal machined castings is a Commodity code covering the repair, maintenance, and parts replacement services for centrifugal and positive displacement pumps used in municipal water and wastewater infrastructure. State and local governments procure pump repair and overhaul services under this code, with work centered on full-service support including disassembly, OEM-standard inspection and repair, reassembly, installation, and startup. Issuing bodies include municipal departments responsible for water and wastewater systems; the City of Atlanta Department of Watershed Management represents a major recent buyer in this space, soliciting multi-year repair and maintenance contracts supporting multiple pump classifications across facility portfolios. Vendors must maintain or access machine shops, field service capability, and personnel certified in pump shaft alignment, welding, and confined-space entry to compete. Successful bidders typically commit to fast parts availability (90 percent within 24 hours, balance within 72 hours), one-year warranties, and compliance with OSHA lockout/tagout and manufacturer safety protocols, with some pump types requiring manufacturer certification (Watson Marlow and Xylem-Flygt work specified to certified distributors).

Recent activity concentrates in the Southeast, with Atlanta's Department of Watershed Management issuing a Pre-Advertisement Notice (PE66062NONST2026000000372) on May 8, 2026, for comprehensive pump repair and maintenance across nine pump classifications (vertical turbine, horizontal split-case, submersible, centrifugal, vertical chopper, progressing cavity, piston-type positive displacement, Watson Marlow specialty, and vacuum/hydraulic). The City used a multi-step sealed bid process with a prequalification phase preceding the formal Invitation for Bid (IFB), with the prequalification deadline set for May 29, 2026. The contract structure allows the City to adjust quantities without penalty and does not obligate exclusive awards or minimum commitments, reflecting typical municipal flexibility in ongoing repair services. No specific award value is disclosed in the available documentation, and no set-aside or disadvantaged-enterprise designations were named.
