WS Darley & Co

WS Darley & Co Ohler Pump Division, doing business as Ohler Pumps, manufactures specialized pumping equipment, fuel distribution systems, and related components for the U.S. military and federal emergency-response agencies as a small business prime contractor (100% of recent awards), competing predominantly under total small business set-asides on indefinite delivery vehicles without holding 8(a), HUBZone, SDVOSB, or WOSB certifications. Headquartered in Janesville, Iowa, the division is a subsidiary of W S Darley & Co (Itasca, Illinois) and operates as a for-profit manufacturer under primary NAICS codes 333914 (Measuring, Dispensing, and Other Pumping Equipment Manufacturing) and 333911 (Pump and Pumping Equipment Manufacturing), with secondary focus on diesel engines and power distribution systems. The parent company holds a $500 million Special Operations Equipment–Tailored Logistics Support IDIQ with the Defense Logistics Agency and a $7 billion multiple-award vehicle effective through 2068.

Customer concentration is heavily weighted toward Defense Logistics Agency Land and Maritime, which accounts for 194 awards (68% of recent award count) with $14 million combined potential value, reflecting a large volume of small single-award IDIQs valued at $250,000 each for recurring quarterly or annual orders of pump cases, centrifugal pumps, pump impellers, diesel engines, and power distribution consoles. Potential-value concentration diverges substantially: the Federal Emergency Management Agency (4 awards, $55.2 million combined potential value) and the Department of the Army Acquisition Support Center PEO Soldier (3 awards, $50.5 million combined potential value) anchor 97% of combined dollars, driven by two large awards—a $36.87 million Naval Sea Systems Command IDIQ for Expeditionary Fuel Distribution Systems awarded March 2026 and a $49.5 million multiple-award FEMA IDIQ for tank and pump systems supporting disaster relief, both awarded or extended in 2024–2026. The Marine Corps (13 awards, $31 million combined potential value) ranks fourth by dollars but carries an $11.82 million single-award IDIQ for Tactical Aviation Ground Refueling Systems extending through June 2027, under which the division has executed approximately $10.1 million in delivery orders for TAGRS production, refurbishment, testing, and training. The Coast Guard (22 awards, $434 thousand combined potential value) represents volume activity on modest individual orders for pump components and, in late 2023, unmanned aerial systems.

Representative capability work demonstrates breadth across defense logistics and emergency response: a $7.68 million Marine Corps delivery order (March 2026) for an Expeditionary Fuel Distribution System under the new Naval Sea Systems Command IDIQ; a $3.02 million FEMA delivery order (February 2025) for 364 tank pump systems as part of a 1,500-unit disaster relief procurement; a $7.19 million Marine Corps delivery order (July 2024) for Tactical Aviation Ground Refueling Systems production units under the $11.82 million Marine Corps IDIQ; a $2.50 million FEMA delivery order (September 2024) for refurbishment of tank pump system components and spare parts; and a $390.87 thousand Defense Logistics Agency definitive contract (September 2024) for pumping assemblies, fuel under total small business set-aside. The division also supplies niche commodities such as unmanned aerial systems (a $209 thousand Air Force purchase order in September 2025 for NDAA-compliant small UAS, and multiple Coast Guard orders for Parrot UAS units in 2023) and specialized maritime components such as filter/separator modules ($148.6 thousand Naval Sea Systems Command order, September 2023) and hose accessory kits ($120.9 thousand Coast Guard sole-source order, December 2023, with options for up to 100 units total).

Parent-vehicle footprint reflects a mixed-tier strategy: the division holds approximately 15 single-award DLA Land and Maritime $250,000 IDIQs (one awarded or extended nearly every month in 2024–2025 for centrifugal pumps, pump impellers, pump cases, and diesel engines), three significant multi-million-dollar IDIQs with FEMA ($49.5 million, multiple-award) and Naval Sea Systems Command ($36.87 million, single-award, awarded March 2026), the $11.82 million Marine Corps single-award IDIQ, and the parent company's $500 million SOE-TLS and $7 billion DLA vehicles. Top parent vehicles by task-order volume are Indefinite Delivery Contract SPE7MX19D5010 (32 task orders, $659 thousand combined potential value), SPM7LX13D0091 (14 task orders, $929 thousand combined potential value), and M6785422D5000 (7 task orders, $11.4 million combined potential value), which appear to represent recurring DLA Land and Maritime small-order vehicles and Army Contracting Command Warren pump assemblies contracts.

Activity has remained steady at 17–29 awards per year across 2023–2025 (6 awards recorded in 2026 year-to-date through August), with 286 total recent awards totaling $193 million combined potential value. The source identifies $37.2 million in combined dollars obligated (19% of potential value), reflecting the recurrent small-purchase posture typical of DLA Land and Maritime commodity vehicles. Four awards totaling $8.6 million reach ultimate completion within the next twenty-four months, concentrating recompete risk on DLA single-award IDIQs and smaller delivery orders. The division subcontracts minimally: the portfolio carries one identified sub-award as of the source date—a March 2024 Lockheed Martin task order for DODES Support 205A Ground Refueling System work—indicating that Ohler Pumps operates predominantly as prime rather than as a tier-one subcontractor to large integrators.

Capability concentration across product categories shows power and hand pumps (153 awards), diesel engines and components (13 awards), electrical control equipment (17 awards), and commercial hardware (18 awards) as the dominant PSC groupings, with smaller allocations to compressors and motor vehicles reflecting the division's role as a specialized supplier of pump-centric equipment for military logistics and emergency response rather than a full-line defense industrial base player.
