Busch Group brings together two strong brands: Busch Vacuum Solutions and Pfeiffer Vacuum+Fab Solutions. As a global one-stop supplier for vacuum, pressure and leak detection solutions, we combine industrial robustness, high and ultra-high vacuum expertise, application know-how and worldwide service to support customers from concept to operation.

Our focus is clear: vacuum technology. This specialization gives our experts deep and comprehensive knowledge, strengthened by the combination of Busch and Pfeiffer. Busch Vacuum Solutions is a trusted standard across industries such as food packaging, chemicals and plastics, while Pfeiffer Vacuum+Fab Solutions delivers best-in-class solutions for semiconductor, analytics, research and other advanced applications.

For Big Science and R&D, vacuum is not just a supporting technology; it is an enabling condition for discovery. Large-scale research infrastructures such as particle accelerators, synchrotrons, fusion facilities, gravitational-wave observatories and projects like the Einstein Telescope depend on clean, stable and reliable vacuum environments. Busch Group supports these demanding applications with vacuum pumps, pumping systems, high and ultra-high vacuum components, vacuum chambers, customized chambers, measurement and analysis equipment, gauges, valves, feedthroughs, manipulators, exhaust gas purification systems, engineered vacuum systems and quality testing solutions such as leak detectors.

Our portfolio covers applications from rough vacuum to high and ultra-high vacuum, as well as helium and hydrogen leak detection for quality assurance, commissioning and maintenance. Whether the challenge is evacuating large volumes, maintaining sensitive experimental conditions, detecting the smallest leaks, integrating vacuum technology into complex scientific infrastructure, or designing and building tailored vacuum chambers and systems, Busch Group brings proven technology and practical engineering support.

With subsidiaries in 47 countries, 20 production sites and 8,000 employees worldwide, Busch Group combines global strength with local customer proximity and the industry’s largest in-house service network. As a family-owned group, we think in generations rather than financial quarters, with an inventive spirit focused on reliable, sustainable and future-ready solutions.

At the Big Science Business Fair, Busch Group is ready to connect with research organisations, system integrators and industrial partners across Europe, helping reduce technical risk, improve uptime and accelerate innovation for the next generation of scientific discovery.
