Seals for the Industry & Energy

A sealing solution for your pump helping your organisation towards Industry 4.0? Our Liquidyne® pump shaft seal is the upgrade for gland packing and the alternative for a mechanical seal. The Liquidyne can monitor the condition of the seal in a distance, predict the lifecycle of the seal and prevent sudden pump failure.

With the Liquidyne you can:

  • monitor the condition of the seal in a distance,
  • predict the lifecycle of the seal and
  • prevent sudden pump failure.


In industry, the Liquidyne can be found in:

  • Cooling-water pumps
  • Water pumps
  • Firefighting pumps
  • Slurry pumps
  • Jet pumps
  • Process 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.

In a power plant, it is crucially important to be able to rely on your systems, including the cooling-water system. Without a proper cooling process, the power plant would stop running. The Liquidyne is a reliable, predictable and cost-effective seal. Interested?

“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.”
