UNSPSC 31102006: Aluminum centrifugal casting

Aluminum object cast from centrifugal molds

UNSPSC 31102006 Aluminum centrifugal casting is a Commodity code that in recent state and local procurement activity describes repair, maintenance, and parts support for centrifugal and other specialized pump types serving municipal water and wastewater systems. The City of Atlanta Department of Watershed Management's May 2026 Invitation for Bid (IFB) for pump repair and maintenance services across nine pump classifications—including Centrifugal Pumps (Group IV), Horizontal Split Case Pumps (Group II), and Submersible Pumps (Group III)—illustrates the scope of work under this code: full-service support encompassing procurement, installation, disassembly, inspection, transportation, repair to OEM standards, reassembly, startup, and detailed documentation. Successful vendors must operate or access a functional machine shop, field service equipment, and personnel certified in pump shaft alignment, welding, and machinist work, with confined space entry training and compliance with OSHA standards, lock-out/tag-out procedures, and all applicable safety codes. The code reflects purchasing by municipal water and wastewater authorities seeking vendors capable of maintaining critical infrastructure with rapid parts availability (90 percent within 24 hours, 10 percent within 72 hours), one-year warranties, and manufacturer-certified service for proprietary equipment such as Watson Marlow and Xylem Flygt pumps.

Recent activity under this code shows limited geographic spread, with the Atlanta Department of Watershed Management in Georgia posting the primary recent opportunity. The City of Atlanta IFB, due May 29, 2026, follows a multi-step sealed bid process including a prequalification phase before formal bidding and a Pre-Solicitation Conference to address vendor questions. The contract does not disclose a specific award value or budget range. Vendors must provide their own tools, equipment, and safety equipment; bear all costs for plant and facility inspections; and may be required to reimburse the City for authorized travel and lodging expenses within 30 days of invoice. The solicitation reserves no set-aside designations and allows subcontractor use with prior City approval, though the primary vendor remains solely responsible for all work performed.
