Wärtsilä Pumpguard Water WFS MG Seals

A shaft seal with a wide capability, originally designed for demanding marine applications and trusted in both commercial and defence vessels which operate in aggressive waters.  Fitted with water lubricated bearings these seals have high wear resistant Silicone Carbide interfaces for the smaller size range.

Available as fully split or partially split variants.  They are custom designed for each installation, either for new builds or to retrofit to an existing installation, although standardised metric and imperial designs are available.  Fully split versions allow rapid change out of replacement components and reduced downtime associated with major maintenance routines.

Seals can also be supplied utilising Wärtsilä’s latest structural composite material offering large savings in weight. Typically these seals are installed on cooling pumps on thermal and nuclear power plants but have a wide application in pump operation.

A long product life matching the operational profile of the plants where it is installed, offered with global product and field service support capability.
