The Haag + Zeissler ROTATING Series 7201 is a precision rotary union engineered for efficient water transfer in rotating equipment and cooling systems. It supports a maximum operating pressure of 50 bar for DN 8 (1/4") through DN 40 (1 1/2") and 40 bar for DN 50 (2"), ensuring reliable operation across a range of connection sizes. The unit achieves maximum rotational speeds of 3500 rpm for DN 8 (1/4"), DN 10 (3/8"), DN 15 (1/2"), and DN 20 (3/4"); 3000 rpm for DN 25 (1"); 2500 rpm for DN 32 (1 1/4") and DN 40 (1 1/2"); and 750 rpm for DN 50 (2"). Designed for durability, precision sealing, and smooth performance, the Series 7201 delivers consistent, leak-free operation under high-speed and high-pressure conditions. Across North America, Europe, Asia, and worldwide, installation configurations and connection standards may possibly vary according to regional industrial requirements and mechanical system specifications.
