Two successful days of innovation, interaction and high-performance sealing technology
The participation of the poesia group in maintenance Zurich 2025 was a major success. On 26 and 27 November, we presented our latest developments in industrial sealing technology, technical profiles manufactured in-house and customised solutions for demanding pump, valve and machinery applications.
With numerous professional visitors, valuable exchanges and strong interest in specialised sealing solutions, the event once again highlighted the importance of precise and durable sealing technology across the industry.
A strong industry meeting point for maintenance and engineering
maintenance Zurich reaffirmed its position as Switzerland’s leading platform for maintenance, asset reliability, industrial efficiency and engineering solutions.
Key highlights of this year’s event:
- high-level technical discussions
- great interest in innovative sealing materials
- growing demand for customised sealing solutions
- strong presence from mechanical engineering, pharma, food processing and energy sectors
For the poesia group, this was the ideal platform to demonstrate how modern sealing solutions enhance the efficiency, safety and lifespan of industrial equipment.
Our highlights – what visitors were looking for
Industrial sealing solutions for pumps, valves and machinery
High interest was shown in our wide product range, including:
- mechanical seals
- radial shaft seals
- O-rings in NBR, EPDM, FKM/Viton, silicone and PTFE
- flat gaskets
- encapsulated O-rings
Many visitors engaged in detailed discussions on material properties, chemical resistance and high-performance polymers.
Special sealing solutions for extreme industrial requirements
Our special and high-performance sealing solutions were particularly sought after by operators of machinery exposed to:
- high temperatures
- aggressive media
- pressure loads
- continuous stress
Technical profiles made from TPE, silicone and specialised materials
Our technical profile range also attracted great interest:
