Description
Rotary joint for cooling water and hot water. Large Series DP 65-100. Two‑way flow, designed for rotating inner pipe (directly borne in housing). Nominal size DN 80. Rotor connection: K‑flange with centring face and gasket sealing (for DN 40 and larger). Housing connection: radial NPT 2 female thread (B1) and NPT 2 (B2). Seal combination 1 (synthetic carbon 19K – chrome steel 18E). Medium: cooling water, hot water. Temperature range –10…140 °C, pressure range 0.2…10 bar, maximum speed 55000/DN ≈688 min⁻¹. Housing made of lacquered steel. Rotor made of stainless steel. Two ball bearings, factory‑lubricated, maintenance‑free up to 80 °C, for higher temperatures relubrication through easily accessible grease point required. Internal balanced mechanical seal, springs outside medium flow. Inner pipe supported in housing, no elbow required. Connection to rotating pressure system via K‑flange with sealing and centring face. Radial and axial housing connections with right‑hand female thread NPT (ANSI). Anti‑rotation device. ATEX certification optional. Set of drain plugs fits Large Series.
Possible Applications
This rotary joint is specifically engineered for high-performance heat transfer applications in heavy-duty industrial machinery, such as large-scale paper drying cylinders, textile calenders, and plastic film extrusion lines. Its robust construction and internal bearing design allow it to manage the thermal expansion and rotational forces inherent in large-diameter rotating drums that require continuous cooling or heating cycles. The unit is particularly suited for processes involving pressurized water circuits where maintaining a leak-free seal is critical during high-speed operation. By supporting the inner pipe directly within the housing, it eliminates the need for external elbows, making it an ideal solution for compact machine configurations where space is constrained and mechanical reliability under constant thermal stress is mandatory.
