Industrial seals

There is an alternative for gland packing and mechanical seals. An alternative that enables you to monitor the condition of your seal in real-time: the Liquidyne® pump shaft seal.


In industry, the Liquidyne can be found in:

  • Cooling-water pumps
  • Water pumps
  • Firefighting pumps

Because its service life can be monitored, the Liquidyne increases the reliability of your process. This helps you to achieve the maximum maintenance interval, which reduces your total costs.

The most important thing for you as a petrochemical company is that your process keeps running 24 hours a day, 7 days a week. The cooling water process is one of the main support processes. Your cooling-water pumps must always be running. So it is very important to know exactly where you stand. The Condition Monitoring function in our Liquidyne seal makes it the perfect solution.

As a pump manufacturer, you want a seal that seamlessly matches the performances of the pump in its totality. You want your pumps to be reliable and predictable, because you know that this is what your customers are looking for. You want a supplier you can trust, precisely at those times when you need service and support.

Why Lagersmit?

It is time for a completely new technology in industry: lip seal technology. A technology that has proven its worth for decades in dredging pumps and jet-water pumps on ships. The Liquidyne was originally developed for the dredging industry, where the seal is exposed to the most extreme conditions. Used in (cooling) water pumps, this robust seal design has an extremely long service life. And you can even monitor that service life so that you avoid any unpleasant surprises.

“The Liquidyne seal is robust and can stand a good deal. The big advantage is that the extent to which a seal is worn down is measurable. This enables us to better plan maintenance and coordinate these activities with production.”

“Thanks to the robustness of the Liquidyne seal, we hardly need to contact Lagersmit. However, if we do need to call them, we can rely on dedicated and solution-oriented people that will help us to take the right action. This works brilliantly.”
