How do you prevent liquids and dirt from disrupting a process? The answer lies in a component that is often smaller than a coffee cup, but plays a major role in everything from pumps and mixers to heat exchangers.
In this explainer video, we zoom in on mechanical seals. What are they – and what are they made of?
Where are mechanical seals used?
Mechanical seals – also known as shaft seals – are used in rotating equipment such as pumps, agitators, compressors and mixers. Their purpose is to create a tight barrier between the shaft and the equipment housing so that liquids and gases remain within the desired limits. This prevents the medium from escaping and at the same time protects the process environment from external particles and air.
In hygienic applications, the sealing function is crucial. Here, it is not only a matter of operational reliability, but also of protecting the end product from contamination and ensuring that cleaning and CIP processes work efficiently. This applies not only to the food industry, but also to the pharmaceutical and chemical industries, where both documentation and process stability are key.
Mechanical shaft seals are therefore an important part of many industrial plants – both to ensure stable operation and to reduce the risk of accidental leakage or downtime.
Sealing solutions tailored to your needs
In the video, we take a closer look at mechanical shaft seals that are compatible with Alfa Laval pumps – including seals for the LKH series and FM variants with and without flushing function. But the need for reliable sealing solutions does not stop at one manufacturer. That is why we also offer seals that are compatible with equipment from other leading suppliers such as APV, Fristam and Johnson.
Whether you work with standard pumps, mixers or special equipment, you can get a solution that fits your needs perfectly – from dimensions and materials to process requirements. This gives you flexibility in maintenance and allows you to choose the seals that best match your process.
