NIGP 72055: Proportioning Pumps: Chemical Feed, Metering, Positive Displacement, and Injector Pumps (see Also Class 820)

NIGP 72055 Proportioning Pumps: Chemical Feed, Metering, Positive Displacement, and Injector Pumps is an Item code under which state and local governments procure replacement parts, repair and maintenance services, and new equipment for specialized pump systems deployed in water treatment, wastewater reclamation, and chemical feed applications. Recent solicitations show procurement of Watson-Marlow Bredel hose pump components for wastewater operations, polymer blending units and OEM parts for chemical treatment, progressing cavity and piston-type positive displacement pumps for municipal water and wastewater systems, and chlorine booster station equipment and materials for utility authority infrastructure. Issuing bodies include city departments of watershed management (Atlanta, Phoenix, Tucson), county utility authorities (Jackson County, Collier County), county water treatment agencies, and state forestry services. Fulton County's Department of Watershed Management and the City of Atlanta's Department of Watershed Management appear as repeat buyers across multiple recent solicitations, underscoring sustained demand from large municipal water systems for ongoing pump support contracts.

Geographic activity concentrates in Florida (Collier County, Jackson County, Volusia County), Georgia (Fulton County, Atlanta), Arizona (Phoenix, Tucson), and Texas, with additional state-level procurement through Texas A&M Forest Service. Representative recent opportunities include Fulton County's IFB for Watson-Marlow Bredel hose pump parts and replacement components across multiple Water Reclamation Centers (response due July 31, 2026), the City of Atlanta's multi-step sealed bid process for nine pump classifications including progressing cavity and positive displacement pumps (prequalification deadline May 29, 2026), the City of Phoenix's five-year pump supply and services contract covering Aurora, Jacuzzi, and Stranco pumps (sealed offers due May 6, 2026), and Collier County's $3.29 million construction IFB for lime softening improvements including chemical injection systems and proportioning equipment (bids due July 1, 2026). Contracts typically require manufacturer certification, 24-to-72-hour parts availability, OEM-standard repair capability, and compliance with OSHA and safety code requirements. Sole-source procurements also appear, such as the City of Holly Hill's notice for Chemco Systems lime slaking systems and OEM parts, reflecting equipment lock-in driven by proprietary design and compatibility constraints.
