PURE OR PURGE OIL
MIST LUBRICATED
BEARINGS (OPTIONAL)
The same oil requirements applicable to ring oil lubricated
bearings also apply to oil mist lubricated bearings.
The steps necessary for oil mist lubrication are as follows:
1 Follow oil mist system supplier’s instructions.
2 Connect oil mist supply lines to oil ring inspection plug
connections (Fig. 19) (Note that only one of the two connection
ports in the radial bearing housing is used [immediately above the
single row radial bearing] while both connections on the thrust
housing must be connected since there are two rows of bearings.)
3
For pure oil mist, connect drain lines to outlet
connections (not required for purge oil mist).
MAINTENANCE OF SHAFT SEALS
MECHANICAL SEALS
When mechanical seals are furnished, a manufacturer’s
reference drawing is supplied with the data package. This
drawing should be kept for future use when performing
maintenance and adjusting the seal. The seal drawing will
also specify required flush liquid and attachment points.
The seal and all flush piping must be checked and installed
as needed prior to starting the pump.
The life of a mechanical seal depends on various factors
such as cleanliness of the liquid handled and its lubricating
properties. Due to the diversity of operating conditions it is,
however, not possible to give definite indications as to its
life.
The mechanical seal must have an appropriate seal
flush system. Failure to do so will result in excess heat
generation and seal failure.
Cooling systems such as those for bearing
lubrication, mechanical seal systems, etc., where
provided must be operating properly to prevent excess
heat generation, sparks, and premature failure.
Sealing systems that are not self purging or self
venting, such as plan 23, require manual venting prior
to operation. Failure to do so will result in excess heat
generation and seal failure.
NOTE: Oil mist is recommended for use on ball
bearing arrangements only (See Appendix I).
NOTE: The standard TSMP is supplied with seal
chambers designed for cartridge mechanical seals.
