Teva Pharmaceutical Industries is one of the world’s leading pharmaceutical companies and, through its ratiopharm brand, is one of the best-known manufacturers of medicines in Europe. Medicines are produced in highly automated manufacturing environments in accordance with the strictest standards of hygiene, purity and process safety.
About the pharmaceutical industry
Across various applications within pharmaceutical production environments, the challenge lay in designing sealing and plain bearing solutions for sensitive processes subject to the most stringent hygienic and
regulatory requirements. The components used had to be permanently resistant to cleaning agents, hot steam sterilisation, and fluctuating temperatures and pressure conditions. At the same time, the focus was on high process reliability, minimal particle formation and long-term plant availability.
‘In the pharmaceutical industry in particular, it is not enough simply to provide a technically viable solution. What is crucial is an understanding of the entire process and the specific operating conditions.’
Harald Nitzschke, CEO of ttv
Among other things, FDA-compliant elastomers, PTFE-based materials and high-purity material combinations for sensitive pharmaceutical applications were used.
Application-specific solutions have also been integrated into the field of plain bearing technology. Maintenance-free and media-resistant plain bearings have been used for guidance, conveyor and motion systems within the production facilities.
This has ensured low-wear motion sequences, high resistance to cleaning and long-term stable plant performance.
Sonderanfertigung mit getesteter Performance
In enger Abstimmung zwischen dem Vertriebsteam von VALVOtec und den technischen Ansprechpartnern bei ttv wurden mehrere Prototypen entwickelt, getestet und optimiert. Die Ergebnisse überzeugten: Während die herkömmliche Dichtung durchschnittlich 20.000 Brühzyklen erreichte, hält die ttv-Sonderlösung bis zu 40.000 Zyklen durch – eine Verdopplung der Standzeit und ein klarer Wettbewerbsvorteil für VALVOtec.

Specially designed mechanical seals were used in rotating applications such as pump systems, mixers and agitators, as well as process plants.
The focus was on hygienic designs offering high cleanability and minimal dead spaces. At the same time, the systems had to withstand the stresses of CIP and SIP processes over the long term and ensure a reliable seal for sensitive media.
O-rings for sensitive production environments
In addition, specialised O-rings were used in valve systems, pipe connections, clamp applications and dosing systems. Particular attention was paid to low particle generation, high media resistance and materials compliant with FDA and USP Class VI standards, in order to ensure long-term compliance with the high requirements of validated production environments.
