About the company
W S Darley & Co's Darley Pump Division, a for-profit Subchapter S corporation subsidiary based in Chippewa Falls, Wisconsin, operates as a small business manufacturer supplying specialized equipment and parts to federal agencies primarily as a prime contractor (91% of recent awards) under full-and-open and small business set-aside solicitations. The division competes predominantly under Total Small Business set-asides and carries no recurring SBA certifications across its prime footprint.
The Darley Pump Division's capability portfolio centers on firefighting protective equipment, marine and pump systems, engine fuel components, and unmanned aerial systems. Recent representative work includes a $24,492 firm-fixed-price order from the Coast Guard for 109 fuel system parts kits, 96 carburetor assemblies, and 16 rubber gaskets under a Total Small Business set-aside (April 2025); a $13,618 small business set-aside purchase order from the National Oceanic and Atmospheric Administration for a replacement fire/de-watering aft pump for the research vessel Oscar Sette (February 2022); and a $11,636 small business set-aside order from NOAA for four Lion 2K firefighting protective garments meeting NFPA 1971 standards (May 2025). The division also delivered miscellaneous training materials to the Department of State's Bureau of International Narcotics Law Enforcement on behalf of U.S. Customs and Border Protection ($28,078, May 2024) and an unmanned drone to the Coast Guard Sector in St. Petersburg, Florida ($16,079, September 2022).
Customer concentration is heavily weighted toward the Department of Homeland Security's U.S. Coast Guard, which accounts for four awards and $73 thousand of the division's $145 thousand combined potential value across eleven total awards. The Department of State's Bureau of International Narcotics Law Enforcement, the National Oceanic and Atmospheric Administration, and the Marine Corps round out the active customer base. The division operates under one named parent vehicle: an Indefinite Delivery Contract (N0002423D4116) with the Navy. Activity has been episodic — one award in 2020, three in 2022, one in 2024, three in 2025, and two in 2026 — with two awards (combined potential value $32 thousand) reaching completion inside the next twenty-four months. The division subcontracts minimally; a single sub-award under Bowhead Marine Support Services on a Navy P-100 medium-pressure pump labor and material task (October 2025) represents the only documented sub role. The Darley Pump Division is a subsidiary of parent W S Darley & Co, a broader manufacturer and distributor that holds federal contract vehicles and serves the Department of Defense, Department of Homeland Security, and Department of Commerce.
