housings, switches, auxiliary or spare lube oil pump motor, main and auxiliary or spare lube
oil pumps, and valves for damage, installation, cleanliness, and security.
5. Ensure:
a. that seal units are installed, and;
b. that bearings are assembled.
4.1.2.2 Initial Steps in Preparing for Operation of Old Pump That Has Been off-line for
Extended Period
Make certain:
1. that the pump is depreserved in accordance with procedures that assure removal of any
preservative compound which is incompatible with, or will impede, pumpage (or flow);
2. that any rust and corrosion will not affect function of internal assembly, bearings, and seals;
3. that seal flushing piping is free of rust, corrosion, and preservative compound;
4. that lube oil piping and reservoir are free of sludge, foreign materials such as metal particles
and welding beads, moisture, and other contaminant;
5. that lube oil reservoir is thoroughly cleaned with solvent such as kerosene or naphtha and
wiped dry with clean lint free rags.
4.1.2.3 Following Fabrication and Rework of Piping
Flush applicable system as required in FLUSHING LUBE OIL SYSTEM, CLEANING AND
PRESERVING SEAL FLUSH PIPING whenever piping is reworked, a new section fabricated, or
lube oil reservoir is repaired.
4.1.2.4 Servicing Empty Lube Oil System
The principal steps in servicing your pump are outlined below:
1. See that lube oil reservoir, lube oil cooler, filter, and other points in lube oil system where
water or condensation could accumulate are dry.
2. Close reservoir, heat exchanger, and filter drain valves, and any other drain valves in piping
(see LUBE OIL SYSTEM SCHEMATIC drawing).
3. Fill reservoir with lube oil that is specified in OPERATING SPECIFICATIONS until lube oil
level in level glass rises to maximum mark on glass. If there is no mark, lube oil level should
rise higher than 1/2 but no more than 2/3 of the length of the glass. Reinstall reservoir cover.
4. If lube oil console is equipped with temperature controllers, verify that its air regulators are
adjusted to the pressure specified by the lube oil console manufacturer and the temperature
controller setting is as specified in OPERATING SPECIFICATIONS.
5. See LUBE OIL SCHEMATIC drawing in the back of this manual, and line up hand-operated
isolation valves so that flow from the auxiliary or spare lube oil pump is through the system.
Start auxiliary lube oil pump and verify that pressure gauge (PI) on the lube oil console panel
reads the pressure specified on the LUBE OIL SCHEMATIC drawing in the back of this
manual; or in the vendor's instructions in the APPENDIX; or in your plant data file; as
applicable.
