The Haag + Zeissler ROTATING Series MRF (2–8 passages) is a precision-engineered rotary union designed for the transfer of multiple media, including air, non-toxic gases, vacuum, water, and hydraulic oil, in industrial and mechanical systems. It operates at a maximum speed of 250 rpm under 60 bar pressure and up to 10 rpm under 250 bar, ensuring reliable and leak-free performance across a wide range of operating conditions. Built for durability, precise sealing, and long service life, the MRF series enables efficient fluid and gas transfer through multiple channels in rotating machinery. Across North America, Europe, Asia, and worldwide, installation configurations and connection specifications may possibly vary according to regional engineering standards and system design requirements.
