Wärtsilä REguard Water Restrictor Seals

A popular choice of standardised seal for hydropower turbine applications, particularly in the US market. A basic level sealing technology, it can be supplied as a new-build component and as a retrofit part for aging installations.

The sealing interfaces are of industry standard materials and are predominantly segmented carbons, however new material developments are ongoing to improve performance and cost.. Sealing effectiveness is nominally refined by the addition of further [multiple] segmented rings. This seal is typically used in lower pressure applications and is normally supported with a complementary liner to reduce wear and impact on the shaft.

Value can also be offered when part of a package supply, consisting of our high quality seals and bearings plus installation and commissioning, for example.

Applications:
Standard type seal for conventional hydropower turbine shaft sealing
Pumped storage applications
Used in lower pressure applications
