Mechanical seals for the chemical industry

September 26, 2024
Mechanical seals for the chemical industry ensuring technology and safety in fluid handling applications.

Mechanical seals for the chemical industry are elements that require excellent safety and efficiency, as any leakage of corrosive or flammable chemicals that may escape into the atmosphere can endanger a safe working environment and fail to comply with the strictest regulations.

In this blog post we explain the importance of mechanical seals and why at Lidering we are experts in manufacturing mechanical seals for the chemical industry.

What is a mechanical seal and what is it for?

A mechanical seal is an element specifically designed and manufactured to join systems together and to prevent fluid leakage. By ensuring a perfect sealing, mechanical seals serve to prevent any leakage that could compromise the safety of the environment, as well as actively helping to protect the environment from contamination with hazardous substances.

When it comes to mechanical seals in the chemical industry, safety and efficiency are essential, as any leakage of corrosive or flammable chemicals can seriously compromise the safety of workers and the environment, as well as violate environmental regulations. 

Aware of these challenges, we specialise in the manufacture of mechanical seals specifically designed for the demanding applications of the chemical industry.

Materials and applications of mechanical seals in the chemical industry

The material selection in the manufacture of mechanical seals for the chemical sector is essential. At Lidering we use materials of the highest quality and chemical resistance, capable of withstanding the most aggressive and corrosive, clean, with particles or viscous liquids, as well as chemicals operating at high temperatures and pressures. Among the materials we use are PTFE and perfluoroelastomer, known for their durability and chemical resistance.

But as we have told you, the chemical industry covers a wide range of applications, each of which has specific requirements in terms of chemical and mechanical resistance. Here are some of the most common applications and the types of mechanical seals recommended for each:

PTFE bellows and double cartridge seals for corrosive fluids and viscous products used in industrial applications.

Mechanical seals for chloride and acidic derivatives, caustic products

For corrosive fluids, such as chloride and its derivatives, as well as caustic products, PTFE bellows mechanical seals are the ideal choice. These seals offer excellent chemical resistance and ensure the sealing required for these critical applications.

Chemical mechanical seals for detergents and viscous products

Detergents and other viscous products require sturdy solutions that can handle high viscosity without compromising sealing. For these applications, dual cartridge seals are highly effective, providing a reliable and durable seal.

Mechanical seals for fertilisers and chemically aggressive fluids

Fertilisers and other chemically aggressive fluids present unique challenges due to their corrosive nature. PTFE bellows seals are again the right solution, thanks to their superior resistance to aggressive chemicals.

Mechanical seals for varnishes and paints, sticky products

Sticky products, such as varnishes and paints, require seals that can maintain sealing without clogging. In these cases, double cartridge seals accompanied by tanks are recommended to ensure continuous and efficient operation.

Mechanical seals for pulp and paper, pasty products, chemical sector

In the pulp and paper industry, where pasty products are common, double cartridge seals and auxiliary elements such as tanks guarantee an effective seal in every phase of the process, avoiding leaks and ensuring the integrity of the product.

Manufacture of customised mechanical seals

As you see, at Lidering we understand that every application in the chemical industry can have unique requirements. That’s why we offer the possibility to manufacture custom mechanical seals for the chemical industry.

The manufacturing process at our production center in Reus, Spain, uses advanced technology to guarantee the highest quality of our mechanical seals. From material selection to final assembly, each step of the process is carefully supervised by our team of engineers, who work closely with customers to analyse their specific needs and design customised prototypes.
