Rotary Shaft Seals Keep Vitamin Manufacturing Healthy


How Rotary Shaft Seals Keep the Vitamin Manufacturing Industry Healthy

During a world pandemic, the demand for the vitamin market is in a steep climb, and it looks like it won’t peak anytime soon. New studies are beginning to indicate that vitamins are helpful in preventing illness. Even before the pandemic, in the United States, more than 68 percent of the population was using dietary supplements. This has rapidly been increasing since the outbreak. Worldwide, the market for dietary supplements, including vitamins, was $132 billion in 2016. By 2024, the market is expected to grow to $278 billion. If there’s an end in sight, nobody is claiming to see it.

With this kind of growth, advanced vitamin manufacturing industry tools to improve productivity and safety are growing in demand. Manufacturers know they need all the tools they can come by to keep up with demand. Sometimes these tools come in unexpected shapes, including rotary shaft seals, like those available from CinchSeal, a leading seal manufacturer in the industry.

Rotary Shaft Seals in the Vitamin Manufacturing Industry

First, a little history. Shaft seals have been around for a long time, and they’ve done their job with varying degrees of success. Until recently, they’ve been a source of some annoyance because they tend to need frequent maintenance and replacement. Beyond the annoying part, this tendency to fail has made seals a cause of considerable lost time and money.

The job shaft seals are made to perform is straightforward. They’re designed to stop leakage from the inside and prevent outside contaminants from making their way into the processing environment. Of all the kinds of seals available, rotary shaft seals have proven to perform longer and more reliably by a hefty margin.

For vitamin manufacturers, this is important to the bottom line. Adulterated products can be costly, not only in terms of human health but also in terms of shutdowns and recalls. Installing the best shaft seals is a relatively inexpensive way to prevent losses and damage to reputations.

It all boils down to design

Design is the key to a shaft seal’s success or failure. Rotary shaft seals address these design problems:

  • Lip seals and other alternatives feature small surfaces for grabbing the rotating shaft and are more likely to allow leakage
  • Other seals are not good at holding high pressure
  • Harsh environments cause other seals to wear out quickly, resulting in higher maintenance and replacement costs
  • Damage to the shaft can occur because other seals are stationary, creating friction as they rub against the shaft

How CinchSeal rotary shaft seals solve the problems of the past

CinchSeal shaft seals not only remove the design weaknesses listed above but they also build on the advantage. CinchSeal rotary shaft seals:

  • Provide a much larger shaft-seal interface surface to form a far better seal against leakage and contamination
  • Prevent damage to the shaft by employing an elastomer that spins with the shaft instead of rubbing against it
  • Hold high pressure using air purging to push the rotors against the stator, keeping the pressure inside the seal higher than outside the seal
  • Make installation and conversion simple with a split design 
  • Can be designed and built for a specific application when a standard seal won’t do the job properly

A few things for vitamin manufacturers to think about

As they consider ways to make their operations more efficient, safe and profitable, vitamin manufacturers should look at:

  • The role shaft seals play in their process and the ways they help or hinder it
  • A comparison of shaft seal alternatives that takes into account ability to stop leakage, performance, ease of repair and replacement, and length of service life
  • The potential need for a custom solution that would allow for improved equipment performance

Design innovations have helped create a rotary shaft seal that outperforms shaft seals of the past. They make CinchSeal rotary shaft seals the ideal solution for vitamin manufacturing.

For over 25 years, CinchSeal has been a leading manufacturer of rotary shaft seals for screw conveyors, ribbon blenders, and all kinds of bulk-handling equipment. CinchSeal products serve as replacements and major upgrades that make the need for machine replacement less likely.
