by Sweta Shah HR Executive in Ambica Machine Tools

A mechanical seal seems like a mere art when it comes to the sealing of the rotating shafts. Agitators, pumps, expansion joints, and other rotating equipment are used in all industrial production plants. All of these machines have one thing in common i.e. mechanical seal. It provides support to connecting parts of machine or installation.

In addition to this, it joins parts together and keeps flow secure from leakage. Whenever a rotating shaft moves fluid, mechanical seal plays a key role in sealing process fluids from entering the mechanical system. Mechanical seals are often used in pumps handling dangerous as well as safe liquids that must be contained within the unit.

Benefits of Mechanical Seals

There are many advantages of mechanical seals over conventional packing which are listed below.

· Leaking is the primary issue that is addressed by seals. The most vital benefit of the mechanical seal is that it allows a pump to function leak-free.

· When it compares to conventional packing, mechanical seals handle all types of fluids including acids, salts, and abrasive particles.

· It is capable to handle Bi-directional shaft rotation, large pressure, speed excursions, and temperature.

· Apart from these benefits, mechanical seals have long operating life than packing and lip seals and these seals do not cause shaft wear.

· These seals can adjust to different faces of wear as they come with inboard springs which reduce the necessary daily maintenance that needs to be done for the seal to work optimally.

Types of Mechanical Seals

Basically, there aretwo types of mechanical seals available in the market one is single mechanical seals and double mechanical seals, but 90% of installations are done with single mechanical seals. However, many mechanical manufacturers in India have come up with wide range in mechanical seals.

Balanced seal, unbalanced seal, rotating seal, stationary seal, and vertically or horizontally mounted seal are different type of mechanical seals. In all, the rotating seal is the most common and is used when the component that holds the springs rotates with the shaft. In contrast, the stationary seal is used when the component that holds the springs is held stationary in the gland plate.

In every type of mechanical seal, the quality and making of a seal are essential. Application of the correct seal for the right function is extremely important. Nowadays, many pump seal manufacturer in India provides the complete knowledge of correct mechanical seals as per your requirement.

Conclusion

If you have made up your mind to switch from packing to mechanical seals, it would be one of the best decisions you’ve ever made for your engineering project. Whenever you plan to buy one make sure you buy from a trustworthy centrifugal pump seal manufacturer or from mechanical seal manufacturer in India.Buying mechanical seals from the reliable manufacturer will saveyour valuable time and money.
