WS Darley & Co

WS Darley & Co's Ohler Pump Division, doing business as Ohler Pumps, manufactures specialized pumping equipment, fuel distribution systems, and tactical ground refueling components for the Defense Department, Department of Homeland Security, and civilian emergency response agencies, operating as a small business prime contractor across 284 recent federal awards valued at $193 million in combined potential. The division competes full-and-open on most work without set-aside designations, though it qualifies for and receives several small business set-asides, particularly on smaller Defense Logistics Agency component orders and a $49.5 million FEMA tank-and-pump-systems multiple-award IDIQ. Ohler Pumps is headquartered in Janesville, Iowa and is a division of W S Darley & Co, a Subchapter S corporation and parent manufacturer based in Itasca, Illinois.

Ohler Pumps' customer footprint concentrates heavily on two agencies. The Defense Logistics Agency Land and Maritime dominates by award count at 193 awards worth $14 million combined potential value, driven by high-volume, lower-dollar purchase orders and delivery orders for pump cases, impellers, diesel engines, and power distribution consoles—typically $250,000 single-award IDIQs generating multiple small orders annually. The Federal Emergency Management Agency anchors the dollar concentration with just 4 awards but $55.2 million combined potential value, almost entirely from a $49.5 million multiple-award IDIQ for tank-and-pump systems supporting manufactured housing deployed in disaster relief. The Marine Corps contributes 13 awards worth $31 million, led by an $11.82 million single-award IDIQ for Tactical Aviation Ground Refueling Systems (TAGRS) awarded in June 2022 with performance extending through June 2027. The Department of the Army Acquisition Support Center PEO Soldier anchors 3 awards at $50.5 million, a 2024 Army Contracting Command delivery order for water pumping assemblies ($377,496) under a total small business set-aside, and the March 2026 Marine Corps delivery order for an Expeditionary Fuel Distribution System ($7.68 million). The top five agencies by potential value account for 97 percent of combined dollars; the top five by award count represent 90 percent of awards.

Recent capability work reflects dual-track production and component supply. Prime work includes a $7.68 million Marine Corps March 2026 delivery order for fuel pumps and filters to support expeditionary fuel distribution; a $3.02 million February 2025 FEMA delivery order for 364 tank pump systems as part of a 1,500-unit procurement; a $1.93 million FEMA September 2024 delivery order for refurbishment of internal tank pump system components and spare parts; and multiple Marine Corps TAGRS production and refurbishment delivery orders totaling approximately $10.1 million under the existing IDIQ. Component work consists of recurring small orders under DLA indefinite delivery contracts for centrifugal pumps, pump impellers, pump cases, diesel engines, and power distribution consoles, with individual order values typically under $100,000. A single sub-award appears in the source: a March 2024 Lockheed Martin sub for DODES support of a 205A ground refueling system.

Activity has declined in recent years from a peak of 29 awards in 2023 to 18 in 2025 and 4 recorded in 2026 to date; the source window captures awards through late July 2026, suggesting incomplete year-end data. Three awards with ultimate completion dates inside the next twenty-four months carry combined potential value of $8.6 million, representing modest recompete exposure. The Marine Corps TAGRS IDIQ ($11.82 million) extends through June 2027 and has executed approximately $10.1 million in task orders to date, leaving roughly $1.7 million in remaining ceiling.

Ohler Pumps holds a portfolio of governmentwide IDIQs anchoring recurring order flow. The Marine Corps single-award IDIQ for TAGRS ($11.82 million, through June 2027) is the largest. FEMA's $49.5 million multiple-award IDIQ for tank-and-pump systems (through October 2029) has generated three significant delivery orders totaling $5.68 million. DLA Land and Maritime maintains roughly fifteen $250,000 single-award IDIQs across centrifugal pumps, pump impellers, pump cases, diesel engines, and power distribution consoles, each structured for recurring quarterly or annual orders with guaranteed minimum quantities. A March 2026 Naval Sea Systems Command single-award IDIQ for the USMC Expeditionary Fuel Distribution System carries a $36.87 million ceiling through March 2031, and the first delivery order under it ($7.68 million) was issued immediately upon award. The top five parent vehicles by task order count are DLA indefinite delivery contracts SPE7MX19D5010 (32 orders, $659 thousand), SPM7LX13D0091 (14 orders, $929 thousand), and M6785422D5000 (7 orders, $11.4 million).

Primary work is categorized under NAICS pump and pumping equipment manufacturing codes (89 awards) and measuring, dispensing, and other pumping equipment manufacturing (36 awards); the top PSC is Power and Hand Pumps (151 awards). All work is performed in Janesville, Iowa except where noted otherwise; place of performance on the FEMA IDIQ and related delivery orders includes Cumberland, Maryland and Selma, Alabama. The company qualifies as a small business and operates across full-and-open and total small business set-aside vehicles without appearing on any 8(a), HUBZone, SDVOSB, or WOSB certifications in the source material.
