New material for use with EALs

With the introduction of regulations such as the US Environmental Protection Agency’s Vessel General Permit (VGP) requiring vessels to use Environmentally Acceptable Lubricants (EALs), it is essential to develop a clear understanding of the effect on seals and components of switching to such lubricants. A major result of this project is the launch of Bi-O-Lion® - a new elastomer compound specifically designed for marine propulsion applications where EALs are in use.

Our products are globally recognised by marine engineers for their quality and reliability - a position the James Walker name and Lion logo have fostered in the marine industry since the 1880s.

Today we manufacture and supply a highly diverse range of fluid sealing items and other specialised products to the world's commercial and naval fleets, as well as to shipyards and OEMs. For customers' convenience, we maintain a library of charts that give details of James Walker items against OEM part numbers for numerous separators, compressors and diesels.

We also work closely with design engineers of marine equipment to develop sealing products that can be used with confidence in all areas of maritime activity - and have a distribution network that covers virtually every major port across the world.

Metallic Gaskets and Ring JointsMetallic Gaskets

Metakamm® Kammprofile and Metaflex® spiral wound gaskets are widely used on marine pressure vessels and pipelines where the the temperature, pressure, flow rates or vibration are beyond the capability of conventional jointing materials. They are well proven on steam, hydraulic and heat exhanger plant.

Radial Lip SealsRadial Lip Seals

Stabilisers, bow thrusters, stern glands, shaft bearings and distribution boxes are all highly successful marine applications for our Walkersele® range of rotary lip seals. Using our patented Walkersele OSJ-2 (On-Site Joining) technique, seals are maintenance-fitted without stripping down the housing. This can save days of dry docking for a busy vessel - without compromising seal efficiency.
