UNSPSC 31121700: Machined centrifugal castings

UNSPSC 31121700 Machined centrifugal castings is a Class code that in recent state and local activity names pumps and pump-related repair, maintenance, installation, and parts replacement services—a functional scope that deviates significantly from the abstract taxonomy label. The City of Atlanta Department of Watershed Management's May 2026 IFB for multi-step sealed bid procurement of nine classifications of pump repair and support services exemplifies the work actually being solicited under this code. State and local buyers solicit repair and field-service work under the code: the Atlanta solicitation requires vendors to provide full-service support including disassembly, inspection, repair to OEM standards, reassembly, and startup services across vertical turbine, horizontal split case, submersible, centrifugal, vertical chopper, progressing cavity, piston-type positive displacement, Watson Marlow, and vacuum and hydraulic pump types. Successful bidders must own or have full access to a functional machine shop, field service equipment, and personnel certified in pump shaft alignment, welding, and machinist work, with training in permit-required confined space entry. Issuing bodies under this code include city-level departments operating water and watershed management infrastructure; the recent Atlanta procurement represents a city department managing municipal water and wastewater systems seeking ongoing contractor support for pump assets across multiple facilities.

Recent activity under UNSPSC 31121700 concentrates in Georgia, as evidenced by the City of Atlanta Department of Watershed Management's pre-advertisement notice (PE66062NONST2026000000372) posted May 8, 2026 with a response deadline of May 29, 2026. The City will conduct a prequalification phase followed by an Invitation for Bid, with a pre-solicitation conference to be noticed separately. Vendors must supply 90 percent of required parts within 24 hours and the remaining 10 percent within 72 hours, maintain a one-year warranty on parts and services, and submit itemized annual purchase reports to the Chief Procurement Officer within 15 days of each contract anniversary. Watson Marlow pump work must be performed by manufacturer-certified distributors, and Flygt pump work by Xylem manufacturer-certified distributors, establishing specific infrastructure requirements. The City reserves the right to increase or decrease quantities without penalty and is under no obligation to award to a single bidder or commit to a minimum contract value. Payment terms offer a five percent discount for payment within 10 days; otherwise net 30 calendar days apply. No award value or budget range is disclosed in available documentation.
