UNSPSC 31121200: Machined sand castings

UNSPSC 31121200 Machined sand castings (Class) represents industrial pump components and repair services that state and local governments procure to maintain water infrastructure, wastewater systems, and facility operations. Recent activity shows this code encompasses full-service pump repair, maintenance, and parts replacement work — not discrete sand-cast components alone — spanning vertical turbine pumps, horizontal split-case pumps, submersible and centrifugal units, and specialty positive displacement pumps. Issuing bodies are primarily municipal water and wastewater utilities; the City of Atlanta Department of Watershed Management is a representative buyer seeking vendors capable of comprehensive pump support including procurement, installation, disassembly, detailed inspection, repair to OEM standards, reassembly, and startup services. Vendors must own or access a functional machine shop, hold personnel certifications in pump shaft alignment and welding, and comply with OSHA standards and confined space entry requirements.

The City of Atlanta posted an Invitation for Bid (IFB) on May 8, 2026, with a May 29, 2026 response deadline, for multi-year repair and maintenance services across nine pump classifications used in watershed management facilities; the solicitation includes a prequalification phase and requires qualified vendors to supply 90 percent of required parts within 24 hours and the remainder within 72 hours, with a one-year warranty on parts and labor. The scope spans the Southeast (Georgia is the only jurisdiction with recent posted activity in the source). State and local procurement under this code appears limited to municipal water and wastewater departments managing pumping infrastructure; the specific award value is not disclosed.
