What KAISER AG does

KAISER AG is a Liechtenstein-headquartered, family-owned industrial manufacturer founded in 1913, now led by third-generation CEO and owner Markus Kaiser. The company designs and builds specialty vehicles and industrial pump systems across two core product lines: (1) sewer cleaning and industrial disposal vehicles (recycling vehicles, water treatment vehicles, combined vehicles, jetting and vacuum vehicles, dry vacuum vehicles, and compact vehicles under 18 tonnes), mobile walking excavators (S8/S10/S12 Allroad), road-rail excavators (S24RR), and (2) MORO KAISER-branded vacuum and high-pressure pump systems covering five proprietary series — KWP liquid ring, AIR, TURBO, STORM, and WATER vane pumps — plus suction booms, hose reels, PTOs, and Ecotrolley power units. The underlying technology centers on rotary vane pump and liquid ring pump architectures developed since the mid-1980s, delivering airflows up to 16,500 m3/h and vacuum levels up to 93% on flagship systems such as the Cerberus Twin Boost and Hercules.

The company operates eight production and sales locations across Liechtenstein, Germany, the United Kingdom, India, Finland, Italy, Slovakia, and the United States, supported by twelve own sales and service locations and more than 100 international sales and service partners, with vehicles in operation in over 120 countries. The 2026 acquisitions of Whale Tankers Ltd. (UK/India) and Assmann GmbH (Germany) expanded headcount to approximately 1,500 and added Indian manufacturing capability alongside deeper German and UK market positions.

KAISER's revenue model is anchored in B2B hardware sales of capital equipment priced project-by-project, complemented by after-market service, spare parts, and KAISER Connected Services for fleet operators. End customers are primarily municipalities, environmental service contractors, construction and infrastructure firms, railway operators, and industrial facilities requiring high-performance vacuum, recycling, water treatment, and difficult-terrain excavation equipment. Distribution combines direct enterprise field sales with a regional partner network; no public pricing, disclosed revenue, or institutional shareholders exist, consistent with its status as a privately held family enterprise.
