Lidering’s mechanical seals for the chemical sector are the answer to the most critical challenges of applications in this industry.
In the chemical sector, safety is top priority. The need to prevent leaks of corrosive or flammable products that could escape into the atmosphere is crucial for keeping work environments safe and complying with regulations. Lidering’s mechanical seals are specifically designed and manufactured to handle this challenge by guaranteeing perfect water-tightness and preventing any leak that could compromise the safety of the area, thereby also actively helping to protect the natural environment.
The importance of choosing the right materials and of the assembly of mechanical seals in the chemical industry
The materials used to manufacture mechanical seals for the chemical sector are decisive factors. As well as the type of required assembly: whether a single assembly, double, external or according to API plans. At Lidering, we custom-manufacture prototypes of mechanical seals to satisfy the specific needs of every chemical application.
We understand the importance of working with chemically resistant materials of the highest quality, especially for processes that involve liquids that are aggressive, corrosive, clean or viscous or that have particles, and for processes that operate at high temperatures and pressures.
The most typical applications: custom mechanical seals for the chemical sector
The most common seals are double assemblies or those that have a quench system that acts as a safety barrier in the event of leaks, as well as PTFE bellows seals and perfluoroelastomer O-rings.
But given that a mechanical seal for manufacturing detergents is not the same as one for sticky products, or for acid derivatives or caustic products, it is important to know the types of seals that are recommended for each case, as well as the different geometries of mechanical seals and the materials and type of required assembly:
For corrosive fluids, the bellows seal (PFTE) is the optimum choice. It guarantees the necessary water-tightness and chemical resistance required for these types of critical applications (chloride and derivatives, acids, caustic products, etc.).
When it comes to sealing with viscous products such as detergents, our double cartridge mechanical seals offer a robust solution.
The reliable solution for chemically aggressive fluids such as fertilisers is our bellows seal (PFTE), which offers the necessary chemical resistance to handle these challenges.
When you need a mechanical seal that is recommended for sticky products such as varnishes and paints, we opt for solutions such as the double cartridge seals with reservoirs.
For applications that involve pasty products such as paste and paper, we offer a range of mechanical seals for the chemical sector, such as double cartridge seals, as well as ancillary elements such as reservoirs, thereby guaranteeing an effective seal in every phase of the process.
