Reliable performance in many water conditions

Wärtsilä Enviroguard PSE and FSE

Developed to tolerate aggressive waters that may be heavy with silt or sand, the Wärtsilä Enviroguard PSE seal has a long track record of reliable performance in all water conditions through its hard wearing interfaces. The seal is abrasion resistant through its hard wearing interfaces and can withstand large shaft movements without affecting the performance of the equipment.

The Wärtsilä Enviroguard PSE is suitable for both new build and retrofit applications for commercial vessels. The seal is available in sizes between 70mm and 460mm, with fully and partially split options available for ease of seal installation, maintenance and replacement.

Hard Wearing Interfaces
Silicon carbide sealing contact materials are resistant to abrasives and particulates in the water.
