Industrial agitators are key components in numerous production processes. From the chemical industry to the food and pharmaceutical industries, the function of an agitator is to mix or dissolve under controlled pressure and temperature conditions.
At Lidering, we know that an industrial agitator cannot operate reliably without a sealing system designed to withstand certain conditions. That is why we explain the different types of mechanical seals and how we can customise mechanical seal solutions for any type of industrial agitator.
The challenge of sealing in an industrial agitator
An industrial agitator is an almost indispensable element in a factory or industrial plant. And, although there are many types of agitators depending on their type, functions and complexity, in many cases they work in the same way. It is a tank or vessel into which different substances are poured and stirred by a system of rotating blades to promote mixing. These mixtures must be kept under controlled pressure and/or temperature conditions.
This means that a mechanical seal is required that can work against pressure in agitators. Depending on the product, pressure, temperature variations or strict hygiene requirements, a specific mechanical seal model will be needed.
Different seal models for different industrial agitators
As manufacturers of mechanical seal solutions for the process industry, we understand the needs of all industries and know which industrial mixer agitator model is most effective in each case.
LMS28: the mechanical seal for agitators
One of the simplest and highest-performance mechanical seal options is the LMS28 mechanical seal model, a balanced seal specifically designed to operate against back pressure in agitators capable of working at high pressures of up to 15 bar.
Its key features include:
- Ability to operate dry: thanks to its large solid graphite friction face, which dissipates heat and maintains seal integrity even without lubrication.
- Linear speed of up to 2 m/s, suitable for continuous stirring applications.
- DEBRIS system (optional), a special flange that prevents wear particles from coming into contact with the product, thus ensuring the purity of the mixture.
- Integrated wash connections, which facilitate the cleaning of accumulated residues and contribute to compliance with hygiene regulations.
The LMS28 is therefore a sealing solution that combines safety, durability and ease of maintenance, ideal for agitators in sensitive sectors.
They offer versatile and customisable solutions for industrial agitators, adapting to different working conditions and regulated sectors.
LMS23 and LMS27: versatile mechanical seals
In addition to the LMS28, at Lidering we offer other models such as the LMS23 and LMS27, recommended for moderate-speed agitators designed to respond to different agitator configurations.
The LMS27 mechanical seal model is a multi-spring seal in which the stationary part can be equipped with cooling and/or lubrication systems with a flush connection and/or cooling flange.
Both models stand out for:
- Design versatility, adapting to different shaft diameters and working conditions.
- Compatibility with certified materials, suitable for regulated sectors such as food and pharmaceuticals.
- Possibility of customisation, adjusting geometries, materials and auxiliary systems according to the requirements of the customer or agitator manufacturer.
Manufacturers of customised mechanical seals
As Lidering manufactures customised mechanical seals, we can adapt to any requirement, whether for small specific applications or large-scale projects involving agitators.
Our experience allows us not only to design new parts from scratch, but also to customise and optimise existing seals, adjusting them to the actual working conditions of each customer.
This flexibility brings key benefits to agitator manufacturers:
- Greater component durability
- Reduced downtime
- Ease of maintenance
- Certifiable materials (FDA, EC1935) for sectors such as food and pharmaceuticals.
At Lidering, we offer customised sealing solutions that guarantee performance, safety and efficiency in any type of agitator.
