Product catalog summary
Overview: The 7500 Series CinchSeal is designed for zero maintenance due to its unique self-adjusting design, making it ideal for applications such as screw conveyors and bucket elevators. It consumes 30% less power than traditional packing seals and prevents shaft damage, leakage, and contamination.
Specifications:
  • Temperature range: -50°F to 400°F
  • Compatible with C.E.M.A. screw conveyor and bulk handling equipment
  • Accommodates repair kits and flange-mounted bearings
  • Machined from anodized aluminum
  • Handles linear shaft growth and 1/4” total radial shaft runout
  • Purge options: air (5 to 8 psi above vessel pressure) or silicone grease
Design Features:
  • Self-adjusting design eliminates maintenance needs
  • Accommodates shaft vibration, misalignment, and wobble
  • Rotor cup floats against the stator plate to manage lateral shaft movement
Dimensional Chart: The document includes a detailed dimensional chart for various sizes, specifying dimensions A through F for different models.
Components:
  • Housing with O-ring at inboard
  • Inner stator and outboard plate
  • Rotor cup and FDA-approved elastomer boot
Functionality: The 7550 Series uses a special silicon elastomer molded slightly smaller than the shaft for an interference fit, preventing product migration and shaft damage. The elastomer drives PTFE rotor cups against stationary faces to form the primary seal, with the rotor cups designed to be replaceable.
Air Purge System: The seal is air purged, performing best with 5 to 8 PSI of air over vessel pressure, creating an air barrier, cooling the rotating faces, and enhancing seal face pressure to prevent leaks.
Installation and Compatibility: The 7500 Series meets all C.E.M.A. dimensions and can easily replace waste packs, plate seals, and packing glands, effectively stopping powder and dust leaks in rotating equipment.

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 stationary...
