DEUBLIN Multi-Passage Rotating Unions
A rotating union connects a stationary pressurized supply line to a rotating machine part such as a cylinder,
roll, spindle, clutch, etc- It can be used to convey virtually any liquid or gas medium: steam for heating, water
or water/glycol solutions for cooling, hydraulic fluids, cutting fluids, air, inert gas or even a vacuum- The task
becomes more complicated when more than one medium must be conveyed simultaneously- This is the role
of a multi-passage union – to provide multiple independent passages for the same or several different media to different rotating feed points within the same axis.
