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.
2.
On the thrust housing, replace the 1/4 in. NPT plug (133H) with an oil-mist fitting. Replace the 1/2
in. NPT plug (551E) with a 1/2 in. to 1/4 in. bushing and insert an oil-mist fitting provided by the oil-
mist system manufacturer.
3.
For pure-oil mist, connect the drain lines (408A) to the outlet connections. This is not required for
purge-oil mist.

Precautions
WARNING:
•
Running a pump without safety devices exposes operators to risk of serious personal in-
jury or death. Never operate a unit unless appropriate safety devices (guards, etc.) are
properly installed.
•
Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
•
Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
•
Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
