UNSPSC 31163014: Rotary coupling

A type of coupling designed to eliminate the use of seals in rotating and reciprocating machines such as seal-less pumps and pistons.

UNSPSC 31163014 Rotary coupling is a Commodity code that in recent state and local procurement activity covers repair, rebuild, and replacement services for electric motors and pumps at water and utility facilities, as well as IT and low-voltage infrastructure installation work tied to facility reconstruction. The code sees activity from special-purpose water districts and county government bodies. West Basin Municipal Water District solicited on-call pump and motor repair services covering electric motors ranging from 1.5 to 800 horsepower across eight recycled water and pumping facilities in Los Angeles County, with scope including emergency and routine repairs, rebuilds, replacements, on-site removal and reinstallation, post-installation performance testing with vibration analysis, and an eighteen-month warranty on equipment, parts, labor, and materials. Contractors must demonstrate a minimum of five years' experience in electric motor repair, maintain valid California Department of Industrial Relations Public Works Contractor Registration, provide five references, maintain a local repair facility, and carry commercial general liability, business automobile liability, workers' compensation, and professional liability insurance. The contract carries a $1,000,000 not-to-exceed amount over a two-year initial term with potential one-year extension. West Basin encourages participation from Small Business Enterprises, Local Business Enterprises, and Veteran-Owned Business Enterprises, offering up to 10 additional evaluation points or price reductions of 3% per qualifying category.

Geographic activity appears concentrated in California and Georgia. West Basin Municipal Water District (Los Angeles County) issued RFP RFPTH0143 with proposals due October 1, 2026, for the pump and motor services noted above. DeKalb County, Georgia issued ITB 2026-076-ITB on June 9, 2026 for reconstruction of the DeKalb Tennis Center, with bids due July 13, 2026; the scope specified IT and low-voltage infrastructure installation including conduit, pathways, cabling, and terminations, though the connection to rotary coupling as a component is indirect and the solicitation emphasizes infrastructure systems rather than discrete coupling products or services.
