Self-Adjusting 7500 Series CinchSeal Our 7500 Series CinchSeals are designed for zero maintenance due to the unique self adjusting design. These are ideal for screw conveyors, bucket elevators, and similar bulk solid applications. The 7500 Series consumes 30% less power than packing seals and will not undercut shafts. Fully assembled and possessing a rugged modular design, our 7500 Series will not leak to foul bearings or contaminate processing areas. • Designed for C.E.M.A. screw conveyor and bulk handling equipment • Designed to accommodate repair kits • Bolting pattern will accommodate flange mounted bearings • The housing is machined out of Anodized Aluminum • Designed to handle linear shaft growth, and 1/4” total radial shaft runout • Purge with air, 5 to 8 psi above vessel pressure, or silicone grease. • Zero maintenance due to unique self adjusting design CinchSeal • 23b Roland Avenue • Mount Laurel, NJ • 08054 856.662.5162 • 856.662.5

The key component in the 7550 solid seal is the elastomer which is molded out of a special silicon material that can handle temperatures up to 400F. The elastomer is molded slightly smaller than the shaft size so that an interference fit is achieved. It is the interference fit of the elastomer and shaft that not only seals the shaft so product can’t migrate past and leak out, but it also causes the internal seal parts to turn with the shaft so that damage to the shaft is eliminated. As the elastomer turns with the shaft it drives a pair of PTFE mineral filled rotor cups against two...
