Rotary joints and rotary unions play a vital role in the pulp and paper industry by ensuring the efficient transfer of steam, water, and process fluids. They are widely used in drying cylinders, press rolls, coating systems, calenders, and paper finishing equipment — delivering reliable performance, improved operational efficiency, and long service life in demanding production environments.
From the dryer section to the press and size press, every rotating connection has a different job to do — moving steam in, condensate out, and precise water flows to the rolls that shape and finish the sheet.
Deliver high-pressure steam inside rotating cylinders to evaporate moisture from wet paper sheets — keeping the drying process continuous at machine speed.
Work alongside internal syphons to extract condensed water and blow steam out of the rotating cylinders — maintaining drying efficiency across the cylinder bank.
Supply cooling or heating water to specialized rolls for accurate surface treatment and temperature control — holding tight tolerances on sheet quality and finish.
The CARBON series and spares below are specified most often for pulp and paper applications. Final selection should be confirmed against your operating pressure, temperature, and RPM.
