Description
Rotary joint for cooling water and hot water. Large Series DP 65-100. Two‑way flow, designed for non‑rotating inner pipe. 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 primarily engineered for heavy-duty thermal management in continuous manufacturing lines where high-volume cooling or heating fluid circulation is required. It is ideally suited for large-scale calendering machines in the rubber and plastics industry, as well as drying cylinders in paper manufacturing, where the non-rotating inner pipe configuration ensures efficient heat transfer without mechanical interference. The robust stainless steel rotor and carbon-chrome seal combination make it particularly effective for processing lines involving high-temperature water circuits that demand reliable, leak-free performance under constant rotational stress. Its design facilitates integration into pressure-fed systems where precise temperature control is critical for maintaining material consistency during high-speed production cycles.
