UNSPSC 41104816: Vacuum or centrifugal concentrators

UNSPSC 41104816 Vacuum or centrifugal concentrators (Commodity) covers pump systems and related equipment that state and local governments procure for wastewater operations, emergency response, and specialized industrial processes. Recent activity shows substantial demand for wastewater pump station maintenance, repair, and equipment renewal services, particularly through master service agreements that combine scheduled maintenance with emergency response; the City of Gallup, New Mexico procured a trailer-mounted diesel-driven centrifugal pump system for bypass pumping and emergency response under ITB-2621, while Seminole County Board of County Commissioners in Florida issued multiple iterations of a master service agreement (most recently CC710026HSMA, due August 5, 2026) for comprehensive wastewater pump station R&R encompassing force main connections, bypass pumping, wet well cleaning and coating, pump and piping replacement, electrical and instrumentation work, concrete restoration, and confined space operations. Issuing bodies are primarily county utilities departments and city wastewater divisions; Seminole County appears as a repeat buyer with two overlapping solicitations for the same work (one posted May 13 with response due June 17, 2026; a revised version posted July 13 with response due August 5, 2026). The City of Tampa Wastewater Department also appears as a repeat buyer, soliciting oil-lubricated rotary vane vacuum pumps (April 23, 2026 due May 1) and separately issuing an Intent to Single Source for Q-VAC Priming System components and maintenance services (April 20, 2026). Escambia County Waste Services Department posted two consecutive solicitations for landfill gas collection system pneumatic pumps and appurtenances (one in February 2026 due March 5; a re-solicit in April 2026 due March 27, suggesting the first award did not close).

Geographic activity concentrates in Florida, with four of eight opportunities sourced from Seminole County, Hillsborough County (City of Tampa), and Escambia County; the City of Gallup, New Mexico represents the western activity in the dataset. A Texas A&M University System ITB for a modular high-vacuum training system (TAMUS-ITB-26-0538, due June 12, 2026) and a Santa Clara County RFI for a public health lab information management system (April 7, 2026, due April 22) appear tangential to the core commodity focus and show weak alignment with pump or concentrator procurement. Seminole County's master service agreements demand that contractors self-perform at least 51 percent of work, maintain 24-hour emergency response with one-hour callback, and hold minimum five to eight municipal pump station rehabilitation projects completed in the preceding two to five years; pricing structures hourly labor rates by craft classification with material markups capped at 20 percent and emergency services multipliers of 200 percent. Contracts are generally three-year initial terms with one or two optional renewal periods, issued on a task-order basis with no guaranteed volume. Bid security (5 percent), liquidated damages ($250 per day for delays), and insurance requirements (workers' compensation, general liability, business auto liability, umbrella coverage; carriers rated A- or better by Best's) are standard across these opportunities.
