Juntas Rotativas de Múltipla Passagem (DEUBLIN)

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: steam for heating, water or water / glycol solutions for cooling, hydraulic fluids, cutting fluids, air, inert gas, or even vacuum. The task becomes more complicated when more than one media 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.

Typically, each passage is isolated from all other passages and different media are not allowed to mix. The key to reliable function of a multi-passage union thus lies in the sealing technology. Different seal types are dictated by the operating conditions - temperature, pressure, rotation speed, torque, medium chemistry and passage size.

Deublin Multi-Passage Soft-Seal rotating unions can be used in the widest variety of applications and media. Typical media includes the following:

  • Hydraulic Oil
  • Water
  • Water-Glycol
  • Air (dry / lubricated)
  • Nitrogen
  • Argon
  • Grease
  • Coolant
  • Cutting Oil
  • Vacuum

Applications:

  • Steel industry: ladle turrets for continuous casting operations
  • Plastics & rubber industries: injection and rotary molding operations
  • Machining operations: workholding and clamping functions
  • Aerospace manufacturing and flight simulators
  • Industrial cranes
  • Rail transportation
  • De-scaling operations
  •  ... and many more
