The type Y15 is an all metal bellow seal with hook sleeve for very high temperature application especially in refineries or applications, such as industrial heat transfer media, where the seal chamber is too narrow in radial section to allow stationary mounting.


The seal incorporates state of the art bellows design proven in many thousands of applications around the world. The benefits of Eagle edge welded metal bellows seals for high temperature application are:


Salient features:

  • Complete resistance to temperatures to 425o C without cooling.
  • Superior face tracking reduces leakage and "coking".
  • Special bellows design minimises variation in face load due to shaft expansion or face wear.
  • Resistant to Abrasive particles in pumpage, no shaft/sleeve fretting.

Variations of face material options make the Y15 suitable for a wide variety of applications in the Refining, petrochemical and chemical industry as well as in other industries where secure sealing under extreme temperature conditions is necessary.

Tailor made integral sleeve. No special seals required for installation.

Special EPIL vibration dampeners absorbs shaft variation while extending seal life.
