Wärtsilä REguard Oil OFS E Seals

With a longstanding and extensive installed base across many sectors, this product is continuously being developed. A simple but effective seal solution with base E series rubber bellow seals.  With the option to upgrade to a more standardised Partially Split E [PSE] solution and, if required, a specialist Fully Split E [FSE] solution. We can offer these ranges with composite variants, allowing for ease of maintenance and corrosion resistance.  Developed variants are able to operate with a wide variety of both mineral oil types and also Environmentally Acceptable Lubricants [EAL’s].

Compliant in low to medium pressure oil lubricated applications, this product can be delivered in hybrid form with our water lubricated composite shaft bearings.   The result is reduced overall cost with less components and a lighter, easy to handle product though still providing an integrated, environmental shaft solution.  The product can be split for ease of installation and maintenance with long service intervals, minimising downtime and unplanned costs.
