Description
Rotary joint for transfer of thermal oil. Series DP Standard, variant -800 for thermal oil. One‑way flow, no elbow. Nominal size DN 40. Rotor connection: K‑flange with centring face and gasket sealing (for DN 40 and larger). Housing connection: radial G 1½ 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 ≈1375 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 K‑flange 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 integration into industrial machinery that requires continuous fluid transfer between stationary supply lines and rotating shafts operating with high-temperature thermal oil. Typical deployment environments include calendar rolls in plastics processing, heated mixing drums in the chemical industry, and roller systems in textile finishing lines where precise surface temperature control is mandatory. The balanced mechanical seal configuration and specialized material pairing prevent thermal degradation and leakage when handling hot heat-transfer media under continuous rotation. Furthermore, the robust brass and stainless steel construction withstands the thermal cycling inherent in rubber vulcanizing presses and laminated wood production machinery without premature mechanical failure.
