With 50 years of experience as specialists in sealing systems, we know that the reliability of mechanical seals cannot be left to chance. From petrochemical plants working with corrosive compounds at high pressure to food facilities that require hygienic solutions with strict regulations, the basic supply of mechanical seals is not an option.
Beyond standard supply: the value of technical knowledge
The industrial market demands more than just products. What makes the difference is real knowledge of the operating environment: understanding how temperature affects the behaviour of materials, how fluids interact with elastomers, or how equipment vibrations can accelerate link failure.
At Lidering, the design of sealing solutions is based on this technical understanding and on the experience and knowledge we have in each market. It is not a question of adapting an existing model to the customer’s equipment, but rather of starting from the actual working conditions to design a sealing system that guarantees safety, durability and efficiency. Everything is tailor-made.
This approach enables us to offer customised mechanical seals, designed and manufactured with materials specifically selected for chemical compatibility, industry regulations and extreme operating conditions.
Custom mechanical seals for every industry
Our experience in key industries such as the chemical, petrochemical, pharmaceutical, food, water treatment, power generation and waste recycling industries allows us to identify common failure patterns and anticipate them through applied innovation. Thanks to our capacity to manufacture small series, we can adapt mechanical seals to each of our customers’ needs, thus improving the durability of each seal according to its intended function.
Examples of industrial seal applications by sector:
In the recycling sector, we work with plastic extrusion applications at +400°C. In these cases, our cartridge seals with metal bellows and special gaskets have been designed with integrated cooling connections, allowing the temperature of the sealing environment to be controlled and significantly extending the service life of the component.
Another example of a custom mechanical seal: in the pharmaceutical and food industries, where CIP/SIP cleaning and compliance with regulations such as FDA or USP Class VI are essential, we develop hygienic solutions such as the LWS31 single-component seal or the LDC40H double cartridge, which minimise dead zones and are constructed from materials suitable for food contact.
Or mechanical seals for water treatment, where we design systems with materials resistant to chloride corrosion and capable of operating in environments with variable pressures, solids-laden media or sudden temperature changes.
As you can see, each of these solutions is not simply an adaptation of products from a catalogue, but rather engineering applied from scratch, with a strong component of customisation and technical validation in the laboratory.
Because designing a custom mechanical seal involves mastering not only the geometry of the component, but also its behaviour in relation to:
- Product flow (liquid, paste, abrasive, gaseous)
- Internal and external pressure
- Fluid and ambient temperature
- Chemical compatibility of all materials in contact
- Operating conditions: rotation, cycles, speed, starting torque
Technical support and specialised MRO service
In addition to designing and manufacturing mechanical seals, our knowledge of each industrial sector helps us to be present throughout the entire life cycle of the component: from internal R&D development, mechanical seal manufacturing, technical validation on test benches, dimensional checks and technical documentation, and, of course, by applying our technical and sector-specific knowledge to adapt each solution to the customer’s real needs.
For all these reasons, at Lidering we offer tailored industrial maintenance:
- On-site technical assistance
- Mechanical seal repair and reconditioning service
- Re-engineering of obsolete components
- Reliability improvement studies for critical lines
- Technical documentation and regulatory advice
As you can see, our MRO (maintenance, repair and operations) approach is suited both to plants that require ongoing maintenance contracts and to customers who need immediate solutions for critical situations.
Because, at the end of the day, the difference between a supplier and an industrial partner like Lidering lies in the ability to generate real value: we understand the processes, we speak the same language as the plant engineers, and we provide sealing solutions designed to last, adapted to the real environment and backed by in-depth technical knowledge of each sector and customer. We adapt to you and improve every day to offer you durable and environmentally sustainable solutions.
