Description
Rotary joint for transfer of thermal oil. Series DP Standard, variant -800 for thermal oil. One‑way flow, no elbow. Nominal size DN 20. Rotor connection: left‑hand male thread G 3/4 (ISO 228). Housing connection: radial G 3/4 female thread. Seal combination 3 (metal impregnated synthetic carbon 19W – silicon carbide 18C). Medium: thermal oil. Temperature range –10…160 °C, pressure range 0.2…10 bar, maximum speed 55000/DN ≈2750 min⁻¹. Housing made of brass, bead‑blasted. Rotor made of stainless steel. Two ball bearings, heat‑stabilised for series -800, factory‑lubricated, maintenance‑free up to 80 °C, for higher temperatures relubrication through easily accessible grease point required. Internal balanced mechanical seal. O‑rings Viton®. Additional axial shaft seal for bearing protection. Connection to rotating pressure system via standardized connection piece with sealing and centring face. Radial housing connection. ATEX certification optional. Five drain holes in housing, can be blocked with plugs in dusty environment.
Possible Applications
This rotary joint is specifically engineered for high-precision thermal management in rotating equipment where thermal oil serves as the primary heat transfer fluid. It is ideally suited for integration into plastic injection molding machines, textile calenders, and rubber processing drums that require consistent temperature control during high-speed rotation. The unit excels in industrial drying and laminating lines where the internal balanced mechanical seal ensures leak-free operation under fluctuating pressure conditions. By utilizing heat-stabilized bearings and specialized carbon-silicon carbide sealing faces, this component provides reliable performance in demanding thermal cycles within the chemical processing and synthetic material manufacturing sectors.
