UNSPSC 31102000: Centrifugal castings

Objects formed to or near their desired shape by introducing molten metal into centrifugal molds.

UNSPSC 31102000 Centrifugal castings is a Class code that in current state and local procurement encompasses repair, maintenance, installation, and parts replacement services for centrifugal and related pump equipment used in municipal water and wastewater infrastructure. The City of Atlanta Department of Watershed Management's May 2026 solicitation for comprehensive pump repair services across nine pump classifications — including centrifugal, submersible, vertical turbine, and positive displacement pumps — illustrates the practical scope: vendors must provide full-service support from procurement and installation through OEM-standard disassembly, inspection, repair, reassembly, and startup, with certified personnel trained in shaft alignment, welding, machinist work, and permit-required confined-space entry. Issuing bodies under this code include municipal water and wastewater authorities managing aging pump infrastructure. The work requires vendors to own or operate a functional machine shop, field service equipment, and OSHA-compliant facilities, with ability to supply 90 percent of required parts within 24 hours and remaining stock within 72 hours.

Georgia shows recent activity under this code. The City of Atlanta's pre-solicitation notice (PE66062NONST2026000000372) posted May 8, 2026, with a prequalification deadline of May 29, 2026, will proceed through an Invitation for Bid (IFB) after the qualification phase. The contract structure permits subcontractors under primary vendor responsibility, reserves the City's right to adjust quantities without penalty, and offers a five percent discount for payment within ten days, otherwise net 30. Specific manufacturer-certified distributor requirements apply — Watson Marlow pumps require manufacturer-certified distributors, and Flygt pumps require Xylem manufacturer-certified distributors. The solicitation document does not disclose a specific award value or budget range.
