Style 85

World’s First Split Cartridge Mechanical Seal

Style 85

The Flexaseal Style 85 is engineered to be the easiest-to-install split cartridge mechanical seal on the market. Unlike traditional split seals that require complex assembly, the Style 85 utilizes a unique two-piece design that simply attaches over the shaft and mounts like a standard cartridge seal. This innovation reduces installation time and eliminates common errors associated with handling sensitive components.

Features

The Style 85 Split Cartridge Mechanical Seal Reduces Downtime for Challenging and Time-Consuming Installations

  • The easiest installation of any split cartridge mechanical seal in the world: Simply attach 2 halves over the shaft and mount to the pump like any other cartridge seal.
  • Only split cartridge mechanical seal in the world in which just two pieces are handled: No handling of lapped faces as both are secured safely in cartridge halves. Faces can’t be cocked, chipped or scarred.
  • Only split cartridge mechanical seal in which the impeller can be adjusted without removing the seal: Simply reinstall setting clips, release set screws and adjust impeller position then re-tighten set screws and remove the clips.
  • The only split cartridge mechanical seal fully assembled and pressure tested at the factory: We ensure the sealing integrity of each Style 85 before is sent to the field. This process gives your installation an even higher success rate.
  • No measurements, no shims, no special tools, no glue: Standard cartridge setting clips assures proper axial and radial alignment and makes installation even easier.
  • NSF 61 Certified seals available in all sizes: We provide certification for the entire mechanical seal assembly. Our rigorous testing covers faces, metallurgy, elastomers, and assembly products to meet strict lead and chemical leaching requirements for the entire cartridge.
