What Siebtechnik Tema B.V. does

Siebtechnik Tema B.V., domiciled in Rijswijk, Netherlands, is the Dutch subsidiary of SIEBTECHNIK GmbH, itself controlled by STAFAG International GmbH in Mülheim an der Ruhr, Germany. It operates as part of a globally distributed industrial group of more than 60 companies and approximately 3,700 employees, founded in 1922 and active across Europe, North America, Latin America, Asia, Africa, and Oceania via eight named regional subsidiaries in Germany, the Netherlands, France, the UK, the USA, China, Spain, and Australia. The group's strategy is described as controlled, self-financed growth over a 100-year history, with no external venture or private equity investment disclosed.

The company manufactures industrial process equipment for mineral bulk solids processing and solid-liquid separation. Its core product lines span filtering centrifuges (CONTURBEX screen worm, SHS pusher, TURBOCASCADE sliding, HSG vibrating, QuattroFlexPilot), sedimentation centrifuges (Decanter, TWINCONE, SHORTBOWL) and hybrid screen decanters (TURBOSCREEN, CONTHICK), alongside a full range of screening machines (circular, linear, elliptical, banana-motion, multi-deck, Liwell mobile, and Allgaier tumbler), crushing and milling equipment (hammer mills, jaw, roller, cone crushers, drum and eccentric vibrating mills), and sample preparation / analytical systems (samplers, dividers, pneumatic tubes, LAVIB/SLS/ASM/GAS sieves, AMP/AMAS/ASST automation, gas pycnometry). Subsidiary brands — Steinhaus (screen media and wedge wire), CPC (crushing), Hein | Lehmann (Liwell screens) and the 2024-acquired Allgaier Process Technology — extend the portfolio, supplemented by channel partnerships with Multotec for cyclones and spirals.

Revenue is generated through one-time capital equipment sales (centrifuges, screening machines, sample prep), recurring OEM spare parts and preventive maintenance services, and professional laboratory and pilot-scale testing at the Mülheim technical centre or on customer sites. The go-to-market is enterprise field sales with on-site consultation and quote-based pricing, complemented by event-driven demand generation (e.g., ACHEMA 2027 in Frankfurt) and a multilingual website serving as the primary information and download hub. Primary end markets are Minerals & Mining, the Chemical Industry (including polymer processing), and Food & Dairy, with secondary exposure to Inorganic Salts, Coal, Polymers, Recycling & Zero Liquid Discharge, and Fertilizers.
