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 representing specialized equipment and services state and local governments procure for wastewater treatment, water supply, emergency response, and sludge handling operations. Recent solicitations show active procurement across multiple pump types—including portable rental pumps for hurricane contingency, sludge gravity thickener pumps for municipal treatment facilities, centrifuge and rotary press installations, and comprehensive repair and maintenance services for pump fleets serving water reclamation and wastewater infrastructure. Counties, cities, water authorities, and utilities dominate the issuing-body mix, with Hillsborough County, Florida appearing as a repeat buyer for both contingency pump rentals and specialized equipment and services. Work ranges from single-unit equipment procurement with delivery and installation to five-year blanket purchase agreements encompassing parts, labor, and repair services, with many jurisdictions emphasizing OEM standards, 24/7 availability, emergency response capability, and operator training and commissioning.

The geographic spread centers on Florida (Hillsborough, Collier, Sarasota, Pinellas, Marion counties; Cities of Tampa, Ocala, North Miami Beach), Georgia (Gwinnett County, City of Atlanta, City of Cumming, Douglasville-Douglas County), and Connecticut, with additional recent activity in Michigan, Arizona, Texas, and Oregon. Hillsborough County's ITB for trailer-mounted, sound-attenuated diesel-driven portable pumps with 4-inch and 6-inch capacities for hurricane season (due July 31, 2026; estimated value $5,589,125 over five years) and its sole-source award to Xylem Water Solutions for Flygt pumps and OEM replacement parts (estimated $16,656,100 over five years) exemplify the scale and scope of recent opportunities. Gwinnett County's competitive sealed bid for bypass pumping services on an annual contract (due July 10, 2026) specifies self-priming diesel and electric pumps, submersible units, generators, and both standby and operational rates with equipment operator and technician labor. The Town of Killingly's sealed proposals for a single sludge gravity thickener pump (SEEPEX Model BN35-6LS or approved equal; due June 19, 2026) and the City of Atlanta's multi-step sealed bid for repair, maintenance, and parts replacement across nine pump classifications including vertical turbine, horizontal split case, submersible, centrifugal, chopper, progressing cavity, and piston displacement types demonstrate the diversity of work being sourced and the emphasis on OEM-standard service, field expertise, and rapid parts availability.
