is equipped with aligning pin and key.
3.5 FLUSHING LUBE OIL SYSTEM, CLEANING AND PRESERVING SEAL
PIPING
3.5.1 LUBE OIL SYSTEM
During work on the piping of a pump, dirt, grit, and chips are apt to accumulate inside the piping.
This can happen to new, factory-installed piping that has been thoroughly cleaned as well as piping
on a pump that has been in service for some time. Therefore, to prevent bearing damage from such
matter, it is foresighted to clean and flush the lube oil system following field work on the piping of
any pump, where the work performed involved:
1. storage,
2. installation, or
3. fabrication.
Flowserve recommends the use of either flushing procedure that is given below; however, if your
pump is equipped with an auxiliary lube oil pump, its use is preferred.
NOTE
Regardless of which procedure is used to flush the lube oil
system, it will be necessary to employ a lube oil filter in the
piping, downstream of the lube oil pump. Additionally it will
be necessary to have a differential pressure indicator across
the filter.
3.5.1.1 Flushing Lube Oil System Using Auxiliary Lube Oil Pump
The following flushing procedure applies to a pump that is equipped with an auxiliary lube oil pump.
For illustrations of piping and parts which are referred to in the procedure, see LUBE OIL PIPING
and ASSEMBLY drawings in the back of this manual.
1. Remove inboard journal, outboard journal, and thrust bearings (see PUMP DISASSEMBLY:
BEARINGS). Reinstall upper halves of housings, using only half of parting flange bolts.
2. Remove reservoir cover, thoroughly clean interior with petroleum base solvent such as
kerosene or naphtha, and wipe dry with clean, lint free rags.
3. Fill reservoir with recommended type lube oil (see OPERATING SPECIFICATIONS)
heated, if practicable, to 180°F (82°C).
4. Perform first phase of flushing cycle as follows:
a. Start auxiliary lube oil pump and circulate lube oil for 20 hours.
b. During 20-hour cycle, continuously tap entire length of piping to loosen scale and slag.
c. During 20-hour cycle, periodically check differential pressure indicator at filter for an
increase in differential pressure that could indicate filter is becoming clogged. Consider
indication in relation with such factors as capacity of filter, temperature of flush, pressure
of flush, and general condition of piping. Should consideration point to a clogged filter,
