ZURCON BUFFER SEAL LM
DESCRIPTION:
In heavy-duty applications, leak-free performance and long service life cannot be assured by a single sealing element; therefore, specially developed system seals are arranged in series, building a tandem configuration. Each sealing element in a system has its specific function, and their interaction needs to be secured to incorporate redundancy into the sealing system.
The primary seal, manufactured from Zurcon®material, has excellent wear and extrusion resistance under extreme working conditions. it allows an optimized lubrication film to pass this first barrier, ensuring the necessary lubrication of the secondary sealing element for long service life in order to further optimize the performance, friction and service life of sealing systems using a tandem sealing configuration, Trelleborg Sealing Solutions developed the already known and appreciated capabilities of Zurcon®buffer Seal into a new design called Zurcon®buffer Seal lM.
The single-acting Zurcon®buffer Seal lM is designed as a heavy-duty primary rod seal. The design of the product
incorporates a combination of a Zurcon®sealing ring with a back-up ring. by utilizing two materials, the performance of the product is enhanced and life is extended.
