UNSPSC 23152104: Centrifugal separation equipment or parts or screens

UNSPSC 23152104 Centrifugal separation equipment or parts or screens (Commodity) covers centrifugal and chopper pump equipment, parts, and repair services procured by state and local governments for wastewater treatment and water management operations. Recent state and local solicitations under this code reflect demand for centrifugal pumps, chopper pumps, and conditioning pumps used in engineered wastewater-treatment systems, along with full-service repair, maintenance, and parts replacement. Issuing bodies include county governments and municipal water and wastewater departments; Collier County, Florida and the City of Atlanta Department of Watershed Management represent the most visible recent buyers. Work typically encompasses procurement of equipment meeting specific performance parameters, installation, field service support, OEM-standard repairs, parts supply with rapid turnaround (24–72 hours in some cases), and compliance with OSHA and manufacturer safety standards including lock-out/tag-out and confined-space-entry protocols. Vendors commonly must own or access functional machine shops, maintain certification in pump shaft alignment and welding, and provide detailed inspection and reporting with photographic documentation.

Activity appears concentrated in Florida and Georgia, though the source shows limited geographic breadth. Collier County, Florida issued a Notice of Intent to Single Source FJ Nugent & Associates, Inc. for Vaughan centrifugal, chopper, and conditioning pumps under a three-year contract (October 1, 2026 through September 30, 2029), with objections to the single-source designation due June 10, 2026 (Solicitation PUR17191). The City of Atlanta Department of Watershed Management posted a Pre-Advertisement Notice (Solicitation PE66062NONST2026000000372) on May 8, 2026 for multi-step sealed bid procurement covering nine pump classifications including centrifugal and chopper pumps, with prequalification deadline May 29, 2026 and a formal Invitation for Bid to follow. Vendor requirements include OEM-certified service capability, manufacturer partnerships (Watson Marlow and Flygt/Xylem distributors named explicitly), and infrastructure for comprehensive field service delivery. A separate Sourcewell cooperative RFP for law enforcement equipment (Solicitation 061626, due June 16, 2026) appears misaligned with the centrifugal separation equipment scope and does not reflect meaningful activity under this code.
