ATD GmbH

What ATD GmbH does

ATD GmbH (Antriebs- und Dichtungstechnik GmbH) is a privately held German specialty manufacturer of industrial sealing and drive technology solutions, headquartered in Geldern, North Rhine-Westphalia. Founded in 1994 and operating for roughly 30 years under managing director Markus Mund, the company designs, engineers, optimizes, and manufactures shaft seal systems and related components primarily from modified PTFE (polytetrafluoroethylene) compounds. Its core technical differentiator is a maintenance-free, dry-running cartridge design that eliminates the need for barrier-liquid supply systems and supports continuous operation at temperatures up to 290°C, with special-diameter seals up to 1500 mm and custom endless O-rings up to 2000 x 10 mm.

The company's product portfolio spans ATD-Dichtsysteme shaft seals (floating seals with SMA module, bellows designs, integrated-bearing seals, EDS-type seals), PTFE shaft seal rings and large O-rings distributed under the ATD SEALS brand, ATD-Antriebstechnik drive components (track rollers, support rollers, cam rollers), and a separate industrial filtration line (air filter replacement cartridges, vacuum filters, separators, and pump maintenance kits). FDA approval MAF288 covers its white sealing materials for food-industry primary seals, and a low-dead-space hybrid seal targets pharmaceutical manufacturing. Customer segments are general industry, food, pharmaceutical, chemical, and plant engineering — all requiring hygienic, chemically resistant, or high-temperature sealing.

ATD GmbH monetizes through direct B2B sales of custom-engineered sealing hardware and replacement filters, with quotation-based pricing that reflects the project-specific engineering scope. Distribution is primarily direct within Germany, supplemented by the ATD SEALS partner network for European shaft-seal rollouts and a small e-commerce storefront (filtertechnik.at-d.de) for filter cartridges. The company is privately held by its management with no institutional investors disclosed, and operates with a stated headcount of approximately 5 employees, indicating a lean custom-engineering business model rather than a high-volume catalog manufacturer.

Core offering

ATD GmbH develops, constructs, optimizes, and manufactures proprietary industrial sealing systems based on modified PTFE compounds, delivered as ready-to-install cartridge seals for shaft sealing applications in agitators, screw conveyors, dryers, centrifuges, mixers, and other processing equipment. The portfolio includes FDA-compliant food-industry seals, PTFE shaft seal rings, large-dimension custom O-rings, drive technology components (track, support, and cam rollers), and an industrial filter program covering air filter cartridges, separators, vacuum filters, and pump maintenance kits.

Product overview

ATD GmbH (Antriebs- und Dichtungstechnik GmbH) is a specialized manufacturer of industrial sealing and drive technology solutions based in Geldern, Germany. The company's core product portfolio centers on ATD-Dichtsysteme (shaft seal systems) using modified PTFE compounds, which serve as maintenance-free, dry-running alternatives to conventional mechanical seals and gland packings. These seal systems are offered in various configurations including floating seals with SMA modules or bellows, integrated bearing seals, and EDS-type seals. Complementary product lines include PTFE shaft seal rings and large-dimension O-rings distributed under the ATD-SEALS brand, ATD-Antriebstechnik components (track rollers, support rollers, cam rollers), and a comprehensive industrial filtration program encompassing air filter cartridges, vacuum filters, separators, and maintenance kits with compatible alternatives for major pump manufacturers. The company serves diverse industries including food (FDA-compliant), pharmaceutical, chemical, and general plant engineering, with products characterized by high chemical resistance, temperature stability up to 290°C, and suitability for ATEX protection zones.
