UNSPSC 40151549: Double diaphragm pumps

UNSPSC 40151549 Double diaphragm pumps is a Commodity code. State and local procurement under this code spans water treatment plant equipment, emergency response and disaster relief supply contracts, and specialized pump components for municipal infrastructure. However, the recent opportunities block shows limited direct activity in double diaphragm pumps per se; instead, related pump solicitations dominate—including multi-stage lineshaft bowl assemblies for water treatment, submersible and line-shaft deep well pumps for potable water systems, general pump parts and accessories contracts, metering pumps and chemical injection systems for water quality compliance, and proprietary equipment resale and maintenance for integrated water facility operations. The issuing bodies are predominantly municipal water departments and county water resources divisions, supplemented by county emergency management procurement for disaster response equipment pools that include pumping systems among broader supply categories.

Geographic activity concentrates in Texas, Arizona, and Florida. The City of Phoenix Water Services issued a five-year IFB for Aurora, Jacuzzi, and Stranco pump supplies due May 6, 2026. The City of Tucson Water issued an annual requirements contract for lineshaft pump bowl assemblies for the Hayden Udall Water Treatment facility with a December 15, 2025, bid deadline. Tucson also issued an RFP (250034) for deep well line-shaft and submersible pump installation and removal services across Tucson and Pima County, with proposals due November 6, 2024. Collier County, Florida, issued a notice of intent to single-source TriNova, Inc., for ProMinent metering pumps and fluoride analyzers for water treatment compliance, effective February 20, 2026, through February 19, 2031. Hillsborough County, Florida, awarded a sole-source contract to DXP Enterprises, Inc., for proprietary pump equipment and parts across multiple water, reclaimed, and wastewater facilities at an estimated value of $6.6 million over five years. Gwinnett County, Georgia, solicited sealed bids for particle counter replacement at filter plants due May 8, 2026. Activity is sporadic and concentrated among water departments managing aging infrastructure and emergency response readiness rather than a sustained procurement category.
