Rotary Unions for Pharmaceutical Blending & Mixing Systems
In the pharmaceutical industry, blending and drying processes are critical for achieving consistent product quality and meeting strict regulatory standards. High-performance rotary equipment, such as mixers, blenders, and dryers, must maintain a precise, consistent temperature and achieve media transfer under demanding conditions. Any contamination or interruption of this process can compromise the safety of production.
Reliable rotary unions are essential components for pharmaceutical blending and mixing equipment. These precision-engineered devices enable the safe transfer of steam, water, and other media to rotating components. At DSTI, our custom rotary unions are purpose-built for high-speed, sanitary production, offering seamless integration with pharmaceutical OEM equipment.

ROTARY UNION Rotary Unions Engineered for Sanitary Design & Regulatory Compliance
All of DSTI's rotary unions for pharmaceutical applications are engineered to meet stringent sanitary requirements, including FDA and 3-A standards. Our designs are compatible with washdown and clean-in-place processes, with smooth internal flow paths to prevent cross-contamination. This makes our products well-suited for handling a range of pharmaceutical-grade media, including water, steam, and corrosive or viscous fluids.
