What FlowMark Vacuum Trucks does

FlowMark Vacuum Trucks is a Kansas City, Missouri-based manufacturer of vacuum trucks serving essential service providers across the portable sanitation, septic service, oilfield, grease trap, airport maintenance, and industrial pit cleaning industries. Founded in 2013 and operating under the SkyMark Companies diversified industrial group, the company designs, engineers, and assembles a broad product portfolio in-house — including 999-2,000 gallon portable restroom trucks, 1,000-5,500 gallon septic service trucks, combination septic/restroom units, hooklift trucks, aviation pit cleaners, and pickup-and-delivery trucks — built on chassis from Ford, RAM, Isuzu, International, Freightliner, Hino, Kenworth, Peterbilt, and Mack. Core manufacturing relies on full in-house fabrication capabilities (laser cutting, hydraulic press brake, shearing, tank rolling, and welding) supported by 150,000-350,000 square feet of manufacturing space and $4-6 million in parts inventory.

The company's business model combines hardware sales (complete trucks typically priced $30,000-$235,000 depending on configuration), aftermarket parts (via the dedicated flowmarkparts.com e-commerce site), and maintenance services. Revenue is generated through direct sales — including a named account management team, phone sales, online inventory browsing with credit-based financing, and in-person facility visits — exclusively within the US domestic market. FlowMark claims the nation's largest stock of ready-to-work vacuum trucks for immediate delivery and backs its products with industry-leading warranties (7-year no-leak tank, 24-month vacuum pump, 12-month assembly workmanship).

FlowMark produces 250-260 trucks annually and reports thousands of units operating worldwide. Key strategic partnerships include KC Tank for shared fabrication and Stellar Industries for hooklift hoist integration. The leadership team comprises industry veterans with decades of vacuum truck and tank truck experience. No external funding rounds have been disclosed, and the company remains privately held under the SkyMark Companies umbrella alongside sister brands in refuelers, rail trucks, refined fuel, and tank manufacturing.
