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 is a Commodity code under which state and local governments procure submersible, vertical turbine, and horizontal centrifugal pumps for water and wastewater treatment, distribution, and emergency response. Recent activity shows municipalities and regional authorities buying complete pump units with motors and controls for installation at treatment facilities and lift stations, as well as repair services, replacement parts, and bypass pumping on an as-needed or contract basis. The issuing-body mix spans water departments in cities (Tampa, Port Orange, Ocala, Sanford, Palm Bay, North Miami Beach, Adairsville), counties (Hillsborough, Gwinnett, Floyd, Fulton, Lowndes), special districts (Educational Service District 564 in Texas, Tampa Bay Water), and regional authorities. Repeat buyers include Hillsborough County (five sole-source awards for Flygt and Xylem services totaling over $21 million across a five-year horizon), the City of Ocala (two centrifuge and rotary-press installations), and Gwinnett County (two bypass-pumping contracts). Standardization around manufacturer-specific equipment—particularly Flygt pumps via Xylem—drives substantial sole-source activity; cost avoidance through reduced parts inventory and maintenance consolidation is a consistent justification.

Recent opportunities concentrate in Florida and Georgia. Representative procurements include Hillsborough County's $16.656 million five-year sole-source agreement with Xylem Water Solutions for Flygt pumps, OEM parts, and repair services (SS2600273, sole-source notice posted May 21, 2026); Gwinnett County's ITB for bypass pumping services with a pre-bid conference October 7, 2026 and bid due date October 23, 2026 (BL145-26, competitive, minimum five-year experience required); the City of Ocala's ITB for centrifuge installation at WRS #3 with mandatory pre-bid March 19, 2026 and bid due April 7, 2026 (ITB WRS/260503, lump-sum, ten-year equipment-design experience minimum); and Hillsborough County's ITB for hurricane-season portable pump rentals at an estimated $5.589 million over five years, bids due July 31, 2026 (ITB-26-00326, competitive). The City of Atlanta's pre-advertisement for nine pump-repair classifications (PE66062NONST2026000000372, prequalification phase and competitive IFB to follow) and Fulton County's competitive bid for Watson-Marlow hose pump parts (IFB/GS/DWM/2606-1260240, bids due July 31, 2026) represent ongoing service and parts procurement. Sole-source notices for manufacturer-authorized equipment dominate the posting volume; competitive ITBs for installation, bypass services, and emergency rentals drive larger contract values and longer performance timelines.
