NIGP 50020: Extractors, Centrifugal

NIGP 50020 Extractors, Centrifugal (Item) encompasses centrifugal, chopper, and conditioning pumps for wastewater treatment and municipal water management applications. State and local governments purchase these pumps primarily for engineered wastewater-treatment systems designed to meet specific performance parameters while minimizing operational and maintenance costs. The issuing bodies are primarily municipal departments of watershed management and water utilities, though the code also appears in cooperative purchasing frameworks. Collier County, Florida and the City of Atlanta Department of Watershed Management represent recent buyers, with the latter seeking vendors capable of comprehensive pump repair, maintenance, installation, and parts replacement across nine pump classifications including centrifugal units. Work typically requires vendor compliance with OSHA standards, lock out/tag out procedures, OEM-standard repair capability, and in some cases manufacturer-specific certification (such as Xylem certification for Flygt pumps).

Recent activity concentrates in Florida and Georgia. Collier County, Florida issued a Notice of Intent to Single Source FJ Nugent & Associates, Inc. for Vaughan centrifugal, chopper, and conditioning pumps with a proposed contract term running October 1, 2026 through September 30, 2029 (objections were due June 10, 2026). The City of Atlanta Department of Watershed Management posted a Pre-Advertisement Notice (PE66062NONST2026000000372) on May 8, 2026 with a prequalification deadline of May 29, 2026, seeking full-service pump repair and maintenance support across nine pump groups including centrifugal and vertical chopper units. Sourcewell, on behalf of multiple Washington counties and broader participating entities, issued RFP #061626 for law enforcement equipment (posted May 12, 2026, due June 16, 2026), though this represents a different application outside traditional centrifugal-pump wastewater infrastructure.
