Description
Rotary joint for transfer of thermal oil. Series DP Standard, variant -800 for thermal oil. One‑way flow, no elbow. Nominal size DN 50. Rotor connection: right‑hand male thread G 2 (ISO 228). Housing connection: radial G 2 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 =1100 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 engineered for thermal fluid systems in continuous manufacturing plants where heat transfer media must be fed reliably into rotating drums, rolls, or cylinders. It is typically integrated into calenders, laminators, and heated mixing vessels within the plastics, rubber, and textile processing industries, allowing media circulation up to one hundred sixty degrees Celsius without thermal degradation. The balanced mechanical seal and specialized bearing configuration withstand the dynamic loads and thermal expansion inherent in high-speed rotating machinery. Additionally, the brass housing and stainless steel rotor construction provide the necessary corrosion resistance required in demanding chemical processing and synthetic material manufacturing environments.
