OFX Series
- The OFX CinchSeal is proven effective in sealing equipment that mixes and blends slurries, Semi-solids and dry powders for food applications, as well as many other process industries.
The split CinchSeal satisfies the demands created by new stadards in the work place by eliminating product leakage and contamination, reduction of energy and maintenance costs, and protection of bearings and drive components.
Among the particularly challenging applications we have been successful are: cement, spices, cocoa powder and liquid chocolate, soda ash, gypsum, and many others.
How the OFX Series Works -
The key component of the OFX seal is our elastomer boot that is molded slightly smaller than the shaft size which creates an interference fit that protects the shaft from abrasion damage while also sealing the shaft by stopping material from migrating down it. The boot turns with the shaft and drives and spins the Teflon® hard coated aluminum rotor cups against the wearable stator plates, which forms a seal interface perpendicular to the shaft. The rotors can accommodate 1/4 inch total shaft runout without affecting the seal between the two faces.
The seal is purged with 5 to 7 PSI of air to cool the rotating faces, create pressure to keep the faces together, and it creates a higher positive pressure in the seal cavity which acts as an air barrier to keep material from leaking. The OFX will give you many years of service before a rebuild kit will be required. |

Our OFX Series is offered in the split assembly version.

Purge Options - Typically, the central chamber of the CinchSeal is pressurized with clean air 3-5 psi over the vessel pressure for best results. The CinchSeal can handle a vacuum, and in some special applications unpressurized operation or a somewhat higher pressure may be indicated. Grease-purged is an option with only silicone or synthetic grease.

Installation - The CinchSeal should not be installed on severely worn Equipment. Undercut shafts, excessive float or misalignment should be corrected prior to installation. When correctly installed the CinchSeal should operate for thousands of hours before rebuilding is necessary. When required, rebuild kits are available from CinchSeal.
