3. For pure-oil mist, connect the drain lines (408A) to the outlet connections.
This is not required for purge-oil mist.
5.5.6.1 Convert to oil-mist lubrication
NOTICE:
Make sure that pipe threads are clean and apply thread sealant to plugs and fittings.
NOTICE:
In both housings install bearing end cover (160) designed for oil mist.
You can convert from ring-oil lubrication to oil-mist lubrication in pumps with ball bearing construction.
The radial and thrust end bearing housings (134) have pre-drilled connections for oil mist:
• 1/4 in. NPT connection on the inboard side of each housing (133H)
• 1/2 in. NPT connection on the outboard side (551E)
Purge-oil mist lubrication provides intermittent oil mist in the bearing housing. This system uses the oil
sump in the housing, and requires the oil ring and the constant-level oiler.
Pure-oil mist lubrication provides constant oil mist in the bearing housing. This system does not use the
oil sump, oil ring, or constant-level oiler. The drain connections in the bearing housing are used as part of
the oil recirculation system.
1. On the radial housing, replace the 1/4 in. NPT plug (133H) with an oil-mist fitting provided by the oil-
mist system manufacturer.
The 1/2 in. NPT connection (551E) remains plugged because it is not required in the oil-mist sys-
tem.
