Deublin Co. is a top manufacturer of rotating unions—a class of mechanical device that allows transfer of pressurized fluid from a stationary source into rotating machinery for heating, cooling, or transfer of fluid power. Deublin’s entree into the rotating-union market was its unique design that incorporated balanced mechanical seals. That innovative design began the growth of the company.
Rotating union applications include air clutches, gearboxes, machine-tool spindles, textile equipment, rubber and plastic manufacturing machinery, steel continuous casting machines, and paper-machine calender stacks.
In 1989, the Deublin product line was expanded to include steam joints and siphon systems for paper-machine dryer cans. More recently, they added a full range of electrical slip rings used for the purpose of conducting electrical current or signals into rotating machinery.
