UNSPSC 26111528: Hydrostatic drives

UNSPSC 26111528 Hydrostatic drives (Commodity) encompasses Variable Frequency Drives (VFDs) and related repair, maintenance, and replacement services that state and local governments procure for wastewater treatment, water distribution, aviation, and facility infrastructure systems. Recent state and local solicitations under this code show procurement of VFD equipment from multiple manufacturers (including Yaskawa, Allen Bradley, Eaton, Siemens, ABB, and others), preventative and corrective maintenance contracts, emergency repair services, parts replacement, and programming or refurbishment work. Issuing bodies include city utilities departments (wastewater and water services), county facilities management, state environmental agencies, and aviation authorities. The scope typically requires contractors to provide comprehensive troubleshooting, diagnostics, repair labor, parts sourcing, on-site or emergency response capability, and multi-year service availability across distributed facility locations.

Activity spans Florida, Arizona, Georgia, and Washington, with recent high-profile solicitations from the City of Tampa Wastewater Department (single-source replacement parts and repairs for Yaskawa VFDs, response due September 30, 2026), the City of Phoenix Water Services Department (IFB-25-0749 for a five-year VFD supply and service contract with ten named manufacturers, bids due May 28, 2025), the Washington State Department of Ecology (IFB 2618 ADM for electrical maintenance including 36 VFDs at its Lacey headquarters, bids due July 20, 2026), and the Greater Orlando Aviation Authority (RFP 26-414 for VFD repair and replacement services covering approximately 368 units across multiple facilities, proposals due March 31, 2026). Contracts typically run three to five years with renewal options, require demonstrated multi-year VFD service experience, substantial insurance coverage (often $1 million to $5 million per occurrence depending on facility risk), emergency response capability, and compliance with OSHA, National Electrical Code, and manufacturer specifications. Small business and veteran-owned business set-asides appear in Washington State procurement; prevailing wage requirements apply in some jurisdictions.
