Deublin 904-120-188

Description

• Functional Features: Realize sealed medium transmission under rotating state; Compensate axial and radial displacement during equipment operation; Wear-resistant sealing structure to ensure long-term leak-free operation.
• Performance Parameters: Maximum working pressure: 1.0 MPa; Operating temperature range: -10°C ~ 120°C; Maximum rotational speed: 120 RPM; Leakage rate: Zero leakage under rated working condition.
• Material Composition: Rotor and shell: High-strength cast iron + hard chrome plating; Sealing assembly: Carbon graphite and silicon carbide composite sealing pair; Spring parts: Stainless steel anti-rust alloy.
• Structural Characteristics: Double-end sealing structure; Built-in wear compensation spring; Integrated bearing assembly; Compact overall structure, easy to connect with pipeline and rotating shaft.
• Working Principle: The static shell connects with fixed pipeline, the rotating rotor connects with rotating equipment; Medium flows through the internal channel of rotary union, and the high-precision sealing pair isolates medium while allowing relative rotation between two parts.
• Advantages & Highlights: Excellent wear resistance and sealing performance; Low friction torque, no stuck during rotation; Good adaptability to medium temperature and pressure fluctuation; Long maintenance cycle.
• Applicable Industries: Machine tool manufacturing, Printing machinery, Textile equipment, Food processing machinery, Industrial cooling system.
• Model Series: Deublin 904 General-purpose Rotary Union Series
• Installation Requirements: Coaxial installation with rotating shaft; Ensure pipeline has no external tension and torque; Fix the static end firmly; Keep the equipment running within rated speed range.
• Usage Notes: Filter medium before access to prevent particulate impurities from damaging sealing surface; Regularly check leakage and operating noise; Prohibit operation exceeding rated pressure and speed; Add lubricant according to maintenance cycle.
