Mechanical seals are a very important part of industrial machinery because they preserve the efficiency of the system by preventing leaks.
There are various varieties of mechanical seals, but one type of seals stands out differently due to their unique design and excellent adaptability.
They are known as Bellow Mechanical Seals. These seals play a critical role in several applications and provide great performance and dependability.
Leak-Pack is a reputed name in the world of mechanical seals that provides all types of mechanical seals including Bellow Seals.
metal bellow mechanical seal manufacturers make different types of seals suitable for different types of applications.
What is a Bellow Mechanical Seal?
Bellows Mechanical Seals are also called non-pusher seals.
They are flexible. Bellow mechanical seals have the capability of adjusting to different pressures and temperatures without compromising a tight seal.
This flexibility makes these seals ideal for applications where traditional seals may not be suitable because of vibration or misalignment.
Top five suppliers of mechanical seals suggest the appropriate types of seals based on the requirement.
Types of Bellow mechanical seals
Welded Metal Bellow Seal
These seals are known for their durability, resistance to pressure resistance, and uniform displacement. They are used in applications where the pressure is high and leak-tight performance is critical. Since there are no dynamic ‘O’ rings, the seals do not hang up or damage the sleeve and shaft.
Rubber Bellow Seal
These seals are made from metals like stainless steel. They are quite highly durable and suitable for clean water pumps, piping, or vacuum pumps.
In applications where the temperature is high e.g., oil refineries, petrochemical plants, and wastewater treatment plants for sewage applications; they are ideal.
They have a single coil spring which avoids effluent particles.
Elastomer Bellow Seal
These seals are easy to install, cost-effective, and suitable for various types of fluids. They are designed for general sealing purposes in applications like centrifugal, chemical process, and circulating pumps. The seas have single-coil springs.
PTFE (Teflon) Bellow Seal
These seals are designed to handle highly corrosive chemicals like strong oxidizing and reducing agents, concentrated acids and bases, or chemically active organic components. They are used in pharma industries, chemical processing applications, or other processes that involve corrosive substances.
PTFE (Teflon) Bellow Seals have great chemical resistance. They are non-reactive and can be removed and replaced easily. They are suitable for a wide range of temperatures.
Non-Contacting Bellow Seal
These seals are designed to operate without making any direct contact between the sealing surfaces. Thus, the wear and maintenance are less. They are ideal in applications where you need less wear and friction. The lifespan of these seals is longer.
Conclusion
Bellow mechanical seals are used in various industries because they are very flexible and efficient. A few common applications include chemical processing, oil and gas applications, pharma companies, food and beverage industry and so on. They are capable of handling aggressive chemicals and maintaining a secure seal in highly corrosive environments. They ensure safety by preventing leaks. A contamination-free production process is guaranteed by these seals.
