ROTARY UNION 9 SERIES GENERAL PURPOSE Operating Parameters Steam, Hot Oil, Water MEDIA PRESSURE* 25 psi (Water), 75 psi (Steam), psi (Hot Oil) MODELS ADDED MODELS ADDED TEMPERATURE* 6 F (Hot Oil), 378 F (Steam) 7 SPEED* THREADS /4 Inch to 3 Inch NPT BSP Threads Available Flanged MATERIAL Cast Iron Housing with Stainless Steel or Plated Sleeve Steel CONFIGURATION OPTIONS Mono Flow and Dual Flow Configurations Available * See Performance Charts For Details FEATURES & BENEFITS Advanced Sealing System The Bellows Sealing System provides superior sealing performance throughout the wear life of the Rotary Union. Superior Alignment Dual bearings available in all sizes over /4 to provide superior alignment. Resists Debris Build-Up Compared to seals utilizing springs, the 9 series bellows sealing system is more resistant to debris in contaminated media, which reduces clogging. Easy Mounting The flange attaches directly to the machine journal, providing inherently concentric mounting, minimizing overhang, and partially relieving bearing load to increase service life. 24 www.duffnorton.com Ph: (8) 477-52 Fax: (74) 588-994
