Points To Consider While Purchasing A Rotary Shaft Seal

By Betty Edwards


At home, or even in industries, individual machines require lubrication to operate their best. Lubrication is done through a rotating shaft whose end is closed has a Rotary Shaft Seal. These are low pressure seals that had been designed to fit between a rotating shaft and the body for better pumping while preventing the loss of the lubricating fluid.

There are various profiles of the product in the market and many at times, consumers are challenged while deliberating on the best seal that will ultimately solve their needs. One design common to many individuals is the TC design. Most pump seals are designed with a pre-energized lip and a secondary lip without a spring, though the secondary lip may miss in some products.

As if that is not enough, pump seals can be categorized into various classes depending on their profile. If their application is to go by, some are used in the automotive industry. In most trailers, there are bearing seals that allow the smooth operation of the internal components. Others are categorized depending on their endurance to high temperature and pressure. Additionally, some come inclusive of an enclosed rubber either reinforced or not.

No matter the category that your seal is classified, one thing that cuts across all of them is the fact they are all used in the pumping of a lubricating fluid. The major apparatuses in the pump seal are the rotating and non-rotating components, and without them, there would be high leakages that ultimately make you dig deeper into your pockets.

Technically referred to as end-face rotary shaft seal, these pump seals were designed during the early years of the twentieth century, but their prominence started gaining ground during the post-war era in the forties. It steadily and gradually became a household equipment and as valuable as such to industrialists. Some elements that make the product so unique include the stationary and rotating component, spring, gland plate and clamp ring.

Before the shaft seal was discovered, people majorly relied on gland packings and mechanical packings. They were designed well, though their ability to prevent leakages was low, and that made people less inclined to use them in machines. Moreover, the newly developed models reduce corrosion, thereby enhancing the durability of the equipment. Consequently, people realized a viable alternative in the product.

In fact, durability is one factor that you should always have at the back of your head when purchasing the product. When you set out to acquire one, you have prospects of gaining returns from the acquisition. Therefore, find a product that will serve you for long. To ensure that, look for a dealer or manufacturer who offers a warranty, as it signals that the product is of high quality.

One more thing that you need to consider is the sort of fluid medium that you will be using it on. And while the popular ones are used on oil, other are used on water or a semi-solid lubricant. Therefore, before setting out on the quest for these products, ask yourself the type of medium you will use it for.
