Wear Resistant Chemical Industry Metal Bellows Grafoil Mechanical Seal

Wear Resistant Chemical Industry Mechanical Seal Metal Bellows Seal Grafoil Mechanical Seal

• The seal is highly wear resistant, capable of withstanding the harsh conditions often encountered in chemical processes. It can endure abrasion, corrosion, and high-pressure differentials, significantly prolonging its service life and reducing maintenance requirements. This wear resistance is crucial for maintaining the integrity of the seal and preventing leakage, which is essential in chemical applications where even small amounts of leakage can cause safety hazards and environmental issues.

• The metal bellows in our mechanical seal provides excellent flexibility and compensation for axial movement. It can adapt to changes in the operating conditions, such as thermal expansion and contraction, without compromising the sealing performance. This feature ensures a tight seal even under dynamic conditions, reducing the risk of leakage and enhancing the overall reliability of the equipment. The metal bellows also has good mechanical strength, able to withstand high pressures and vibrations, making it suitable for various chemical processes.

• The incorporation of Grafoil in the mechanical seal offers several advantages. Grafoil has excellent thermal conductivity, which helps dissipate heat generated during operation. This is vital in the chemical industry as it prevents overheating of the seal and the associated degradation of sealing performance. Additionally, Grafoil has a low friction coefficient, reducing wear and energy consumption. It also provides good chemical resistance, further enhancing the seal's durability and suitability for use in a wide range of chemical substances.

Feature:

The Type 609 is an all Alloy C-276 rotating bellows seal, providing high strength and excellent corrosion resistance. It is extremely durable in applications where temperature and media (fluid) result in an aggressive environment. The Type 609 has been tested per API-682 Type B seals for low-temperature refinery services. Other common applications include acids, caustics, amines, and products with H2S, such as sour water and sour hydrocarbons. The Type 609 can be designed as a dual seal using a non-pressurized buffer or pressurized barrier fluid. A pumping ring recirculates barrier fluid, assuring cooler operating temperatures and extended reliable performance.
