How CinchSeal Saves One of the Largest Bakery Companies $100,000 Every Year

The CinchSeal 9700 series of rotary shaft seals are designed for mixing and blending equipment in a variety of industries, from foodservice to pharmaceutical, chemical industries, and even pet food. It’s manufactured entirely out of stainless steel, which is often required in these food processing industries. These industrial bakery solutions offer a number of specific benefits that provide a high return on investment (ROI) for its users.


One of the world’s largest commercial baking corporations was experiencing flour leakage through the shaft penetrations on its commercial bakery mixers, which was contributing to the loss of product and yield. Furthermore, the existing rotary seals were damaging the stainless-steel shafts.


The CinchSeal 9700 eliminated the loss of flour for the company’s industrial dough mixers. It also reduced mixer downtime and protected the shaft from damage. These benefits have provided the company with a documented return on investment (ROI) of $97,736 per year.


The CinchSeal is effective for sealing dryers, paddle mixers and ribbon blenders in bakery equipment, whether they’re used to process dry powders, semisolids, and slurries. These industrial seals are able to seal challenging food materials such as the following:

  • Cocoa powder
  • Liquid chocolate
  • Salt
  • Sugar
  • Spices

The CinchSeal is also successful in sealing non-food items such as cement, plastics and resins.


Installation of the CinchSeal 9700 doesn’t require the removal of existing equipment. Problems with the shaft such as excessive float or misalignment should be corrected before installing CinchSeal, as it must be mounted square to the shaft. Refer to the installation guide for additional details on mounting the seal. Call or visit the website for further assistance.


The seal of the 9700 CinchSeal is made of an FDA-approved elastomer that creates an interference fit around the shaft. This design stops the product from moving past the seal, which reduces waste. It also eliminates shaft wear since the CinchSeal rotates with the shaft.

The seal turns a set of rotor cups made of polytetrafluoroethylene (PTFE), commonly known as Teflon. Both of these components remain under optimum pressure created by a stationary face as they rotate. This pressure creates a seal that prevents the product from getting past the CinchSeal.


CinchSeal’s 9700 is easy to disassemble, clean, and re-assemble for daily maintenance. The PTFE rotor cups are the most wearable parts of the CinchSeal by design. Repair kits are readily available, which consist of two PTFE rotor cups and a split elastomer seal.

CinchSeal’s rotary shaft seals are designed to be purged with five to eight PSI of pressure above the vessel pressure. This arrangement creates a barrier of air that helps keep material inside the tank and away from the seal, adding life to the wearable parts of the seal. CinchSeals should ideally be purged with plant air, although they can also be purged with nitrogen or silicon grease depending on the application. For best results, each split shaft seal should have its own air regulator that isn’t shared by any other seals.


The most common accessories for the CinchSeal 9700 include additional elastomer seals, seal repair kits and air pressure regulators. The CinchSeal is also available with a clean-in-place (CIP) option.

Rotary Shaft Seal Manufacturers

CinchSeal’s rotary shaft seals are USDA-certified to meet sanitation requirements that are required for equipment for commercial bakeries and industrial food production. As one of the top rotary shaft seal companies in the market, we’ve ensured that our designs efficiently seal vapors and dust, which minimizes airborne dust particles. It also minimizes the risk of product contamination that can occur when braided packing breaks down.

The primary benefit of the CinchSeal 9700 is to prevent the loss of materials such as flour, yeast, and water in the case of dough. It also protects the shaft and bearings from wear, reducing downtime and premature failures that result in a loss of productivity.
