UNSPSC 40151570: Mixed flow pump

A pump that is an intermediary between a centrifugal pump and an axial flow pump. It accelerates to the axial direction simultaneously with the centrifugal force for the fluid.

UNSPSC 40151570 Mixed flow pump (Commodity) encompasses portable emergency pumping equipment and specialized centrifuge, rotary press, and submersible pump systems that state and local water, wastewater, and emergency-management agencies procure for treatment infrastructure, sludge dewatering, and disaster response. Recent solicitations span rental and purchase of diesel-powered portable pumps rated 640 to 1,430 gallons per minute for hurricane-season standby, turnkey centrifuge and rotary press installations for biosolids handling, deep-well lineshaft and submersible pump removal and installation services, emergency bypass pumping systems, and acquisition of OEM replacement parts and repair labor for established pump manufacturers including Flygt, KSB, Gardner Denver Nash, and Vaughan. Issuing bodies include county boards of commissioners and utilities departments (Hillsborough County, Gwinnett County, Collier County, Sarasota County), city water and wastewater departments (Ocala, Tucson, Tampa, Cumming, Douglasville), emergency management divisions (Collier County), and specialized water authorities (Douglasville-Douglas County Water and Sewer Authority). Recurring procurement patterns show sole-source awards to manufacturer-authorized distributors for proprietary pump equipment and repair services, as well as competitive sealed bids and invitations for bid on equipment installation and emergency-response standby contracts.
