Effortless Reliability

For ships navigating coastal or challenging waters, a ‘fit and forget’ stern tube seal is essential, and the Wärtsilä Enviroguard PSE seal delivers just that.

With its robust design, high reliability, and extended service intervals, it’s a simple yet effective solution. This design minimises the costs associated with worn shafts, leaking gland plates, and related maintenance. Additionally, the high-resistance interface materials and measures to reduce galvanic corrosion significantly decrease maintenance expenses.

Designed with performance in mind

The partially split design of the Wärtsilä Enviroguard PSE seal, along with its silicon carbide face and seat, makes it durable, robust and simple to install and replace when necessary. It can be replaced with “split” spares during an overhaul without removing the shaft or propeller. This allows for a simple but
very effective sealing arrangement that accommodates both radial and axial shaft movements, resulting in a solution that’s high performing with low maintenance.
