Style 85
Split Cartridge Mechanical Seal:
Flexaseal developed the Style 85 Split Cartridge Mechanical Seal to provide the easiest installation found anywhere in the world.
After simply attaching two halves over the shaft, the seal mounts to the equipment like any other cartridge seal. It doesn't get any easier than that!
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.
