DS Series – Modular Excellence Across the Board
The DS series rotary joints / rotary union for water are perfectly suited for high-speed applications with low torque, especially designed for non-driven rollers. Available in sizes ranging from DN 10 (3/8″) to DN 80 (3 1/2″) in both mono and duo-flow versions, they are tailored for the transfer of water, compressed air, heat transfer oil, and technical gases.
An optional feature for these DS series rotary unions for water includes the addition of a monitoring sensor system for wear parts and other process values. The secret behind Northern Grafics’ success with rotary joints is the intensive development combined with laboratory and practical tests – ensuring high performance for machinery and systems across various industries.
The DS series is designed to be 1:1 interchangeable with previous DP and DX/DXS series, ensuring seamless integration into existing systems. Additionally, the DS series is “sensor ready,” meaning it is prepared for modern, cost-effective condition and process monitoring. This enables improved product quality, reduced energy consumption, and fewer unexpected downtimes.
