Bijur Delimon Lubrication Systems S109 Service Group Filter

The S109 Service Group Filter is Bijur Delimon’s replaceable filter group assembly used in the piston/pump service group of Bijur lubrication systems, compatible with multiple lubricator models including TM-5, YP-8, and L18P families. In the TM-5 service parts catalog, the S109 filter group is listed as the service component for the piston/pump group, with the TM-5 service kit (35726) including the B6527 filter element and a separate filter part identified as 19850. The filter assembly consists of the filter disc with a coarse screen, a fine screen, and is secured by a filter clamp ring and snap ring; maintenance instructions describe removing the snap ring, then the filter disc and screens, and reinstalling in the sequence: filter disc support (coarse screen), filter disc screen (fine screen), filter disc, clamp ring, and snap ring. For ongoing protection, Bijur’s maintenance guidance recommends replacing the filter group annually and inspecting the pump inlet filter every six months to ensure clean oil and uninterrupted flow. The S109 is a standard service part across Bijur lubrication products, designed to simplify field replacement and help keep the lubrication system operating to spec.
