The Haag + Zeissler ROTATING Series 7101 is a high-precision rotary union developed for water transfer in rotating machinery and cooling systems. It supports a maximum pressure of 50 bar for DN 8 (1/4") through DN 40 (1 1/2") and 40 bar for DN 50 (2"), ensuring consistent, leak-free operation under demanding hydraulic conditions. The unit operates at speeds up to 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"), providing reliable fluid transmission across various connection sizes. Engineered for durability, smooth rotation, and precise sealing, the Series 7101 offers long service life and stable performance in high-speed, high-pressure environments. Across North America, Europe, Asia, and worldwide, installation configurations and connection specifications may possibly vary according to regional mechanical standards and system design requirements.
