Rotary Union

LATTY rotary unions are used to create a leak-tight link between a stationary pipe and a rotating pipe, whatever:

Raccord tournant

  • the kind of fluid conveyed,
  • the rotary speed,
  • the range of the motion,
  • the fluid temperature,
  • the number of circuits,
  • the cross-section of the circuit(s),
  • the flow.

We use rotary union:

  • for the transfer of liquid or gaseous substances,
  • within a machine between stationary and rotary parts.

In almost all industrial sectors:

  • Food processing
  • Automobile
  • Chemicals
  • Cosmetics
  • Machine-tools
  • Medical
  • Mining
  • Petrochemicals
  • Paper
  • Steel

APPROVALS (on request) for rotary unions

  • ACS
  • ATEX
  • CE 1935/2004
  • FDA
  • WRAS

For many years, the GROUPE LATTY has been offering rotary unions of various types:

  • with friction seals for gas or liquid applications : Friction seal technologies are used for gas applications (nitrogen dioxide, air, steam, helium, etc.) or clear liquids (solvents, oil, detergents, nitrogen, etc.) and/or associated with slow speed.
  • with mechanical seals with contact for liquid applications : Mechanical seal technologies are used for slurries (chocolate, cream, ice, fuel oil, etc.), transitional pressures/temperatures and/or associated with high speed.
  • with bellows for very high temperature applications.

These various criteria are considered to determine the type of union to be used (Download the Specifications)
