UNSPSC 40151579: Gravity pump

A pump that pulls up to the higher place by transferring into small volume of high-pressure liquid with the massive volume of low pressure liquid by using the water inertia.

UNSPSC 40151579 Gravity pump is a Commodity code that encompasses gravity-driven and pressure-fed pumping equipment for water, wastewater, and utility infrastructure maintenance—specifically equipment serving municipal treatment facilities, pump stations, bypass operations, and emergency response. Recent state and local solicitations reveal purchases of vertical turbine pumps, bypass pumping systems, portable emergency pumps, sludge-handling equipment, and OEM parts and service for standardized pump lines including Flygt, Xylem, Thompson, DiscFlo, and Watson-Marlow units. Issuing bodies span water departments and utilities in mid-size and larger cities, county water resources and stormwater divisions, wastewater treatment authorities, and special-purpose districts. Florida municipalities—Tampa, Hillsborough County, Jacksonville area, Ocala, Sanford, Palm Bay, Port Orange, and North Miami Beach—represent the densest recent activity, followed by Georgia counties (Gwinnett, Floyd, Fulton, Lowndes) and scattered Northeast and Midwest jurisdictions. Sole-source and standardization procurements dominate the code's activity, driven by compatibility requirements with installed equipment and OEM service authorizations; many recent opportunities are non-competitive notices seeking to validate sole-source status or challenge determinations rather than open competitive bids.

Recent representative opportunities include the City of Ocala Water Resources Department conducting two separate ITBs (WRS/260503 and WRS/260536) for turnkey centrifuge and rotary press installations at water reclamation facilities with mandatory pre-bid attendance and March 2026 response dates; Gwinnett County Board of Commissioners issuing an ITB for annual bypass pumping services with responses due October 23, 2026, requiring five years' minimum bypass experience and on-site personnel; Hillsborough County announcing a five-year, $16.656 million sole-source award to Xylem Water Solutions for Flygt pump equipment and repair services under Section 3-205(2)(b) of its procurement policy; and the City of Atlanta Department of Watershed Management launching a multi-step sealed-bid prequalification and IFB process covering nine pump classifications including vertical turbine, submersible, centrifugal, and progressing cavity pumps with repair and maintenance scope. Portable emergency pump rentals appear in Hillsborough County's $5.589 million five-year hurricane-season contingency rental ITB with trailer-mounted diesel-driven units required by June 1 through November 30 annually. Many Florida and Georgia jurisdictions cite standardization and OEM authorization as justification for sole-source awards, signaling entrenched vendor relationships and limited room for new entrants absent OEM distributor status or certified service credentials.
