Seneca Tank

What Seneca Tank does

Seneca Tank is a privately held, family-owned manufacturer of custom-configurable tank trucks and mobile fluid power equipment, founded circa 1970 and headquartered in Des Moines, Iowa. The company designs and builds the ST series of tank trucks (ST2700, ST3500, ST4500, ST5000, ST5800, ST6500) with capacities from 2,700 to 6,500 gallons, integrating PTO-driven pumping systems (dry break and air manifold), multi-compartment configurations (4-8 compartments), and ready-mount pumping systems for lube vans. The underlying technology combines mechanical pumping, hydraulics, blowers, compressors, and meters from established component brands (Gardner Denver, Muncie, Blackmer, Dixon, Roper, Liquid Controls) installed on chassis from Kenworth, Freightliner, Peterbilt, Western Star, Volvo, International, and Mack.

The company generates revenue through five streams: sale of ST-series tank trucks, lube vans and ready-mount systems, tank unloading components (tractor-mounted pumps, orbit motors, blowers, compressors, whip hose systems), online parts sales via parts.senecatank.com, and service revenue from express repair, OEM assist, refurb/changeover, and tractor modifications. Pricing is custom-built to order via direct phone inquiry or Request a Quote; no public pricing exists and multi-unit fleet pricing is available. Seneca Tank serves primary use cases in bulk lubricants, construction and commercial, fleet fueling, railroad/DTL fueling, agriculture, and DEF delivery, with secondary use cases in chemical transport, food grade, dry bulk, fuels, and lubricant unloading.

The go-to-market is enterprise field sales conducted through three company-owned dealerships (Des Moines IA, Springfield MO, Wichita KS), direct phone sales (515.262.5900, 800.362.2910), trade shows (PACE, WPMA), and a website with rolling stock inventory. Seneca Tank is ASME and US DOT accredited and operates with 51-100 employees, three physical locations, and a nationwide online parts storefront.
