The Haag + Zeissler ROTATING Series MRF (9–11 passages) is a multi-channel rotary union designed for the transfer of air, non-toxic gases, vacuum, water, and hydraulic oil in advanced industrial systems. It operates reliably at a maximum speed of 250 rpm under 60 bar pressure and up to 10 rpm under 250 bar, ensuring stable and leak-free performance across a wide range of process conditions. Engineered for precision, durability, and long service life, the MRF series enables efficient fluid and gas transmission through multiple passages, making it ideal for complex rotary equipment. Across North America, Europe, Asia, and worldwide, installation configurations and connection options may possibly vary according to regional mechanical standards and application-specific system requirements.
