How we help make locks reliable

Lock gates must be able to move and ships must be able to sail. For these reasons you must be able to rely on your seals. Supreme® seals provide added value to the quality and reliability of your lock and/or ship. The goal: to effectively separate water and lubricants.

Rijkswaterstaat & Lagersmit

In 2009, the Directorate-General for Public Works and Water Management (Rijkswaterstaat) replaced 64 shaft seals in the Roompot Locks with Lagersmit shaft seals. Rijkswaterstaat was looking for a reliable, environmentally friendly solution. The lock gates each weigh over 230 tonnes. Their role in the Eastern Scheldt storm surge barrier is to effectively seal the Roompot Fairway.

Rijkswaterstaat values Lagersmit’s flexibility and fast delivery times. Lagersmit has a great deal of expertise in lock-related solutions, as a result of which Rijkswaterstaat is a well-known entity for us. Rijkswaterstaat made use of approximately 80 shaft seals for the locks in Hansweert in the Netherlands.

Lagersmit seals

The Supreme Standard is one of the basic designs of the Supreme versions. This seal can be expanded with a large number of options and can be tailored to suit your specific needs. The Supreme seals are suited for use in oil- and grease-lubricated applications.

The Supreme seal provides you with the following benefits:

  • Robust design that has been applied to thousands of propulsion systems
  • Modularly tailored
  • Low total consumption costs
  • Optimal maintenance intervals

The Supreme Standard rear seal consists of bronze housing components, a chromium steel bushing, a single oil-retaining lip seal and two water-retaining NBR lip seals.

The Supreme Standard front seal consists of iron housing components, a chromium steel bushing and two oil-retaining lip seals. With a list of advanced options, such as HML (Hard Metal Layer) coating for more durable bushings, you can equip your seal with additional features.
