Rotary Union| 3 passages |GP(S) 131

Versatile, efficient and multichannel

The GP and GPS (stainless steel) Series multiple passage rotary unions are available in 2, 3, 4, 6, 8, 10 & 12 passage models. They meet highly demanding requirements in terms of pressure and rotating speed for applications with liquid, air or vacuum. Modified or specialized configurations are also available.

All GP and GPS Series rotary unions incorporate exclusive DynaSeal™ seals, which are suitable for vacuum and bidirectional pressures up to 51.5 MPa (515 bar). All passages are individually sealed to allow use with dissimilar medias. They can be combined with a wide range of standard or custom slip rings.

Advantages

  • Multipurpose solution for air, gas, oil, water or vacuum
  • Easy integration
  • High performances (pressure, rotating speed)

Benefits

  • Avoid the need of complex piping arrangements
  • Increased machinery performances
  • Paiping maintenance mitigated
