Check bearing temperature with a thermometer, not by hand. If bearings are
running hot (over 180°), it may be the result of too much lubricant. If changing the
lubricant does not correct the condition, disassemble and inspect the bearings.
Check grease lubricated bearings for saponification. This condition is usually
incurred by the infiltration of water or other fluid past the bearing shaft seals and can
be noticed immediately upon inspection, since it gives the grease a whitish color.
Wash out the bearings with a clean industrial solvent and replace the grease with the
proper type as recommended.
Check the packing and replace if necessary. Use the grade recommended. Be sure
the seal cages are centered in the stuffing box at the entrance of the stuffing box
piping connection.
Check shaft or shaft sleeve for scoring. Scoring accelerates packing wear.
Check alignment of pump and motor. Shim up units if necessary. If misalignment
recurs frequently, inspect the entire piping system. Unbolt piping at suction and
discharge flanges to see if it springs away, thereby indicating strain on the casing.
Inspect all piping supports for soundness and effective support of load.
Remove the rotating element. Inspect thoroughly for wear, and order replacement
parts if necessary.
Check wearing clearances.
Remove any deposit or scaling. Clean out stuffing box piping.
Measure total dynamic suction and discharge head as a test of pipe connection.
Record the figures and compare them with the figures of the last test. This is
important especially where the fluid being pumped tends to form a deposit on
internal surfaces. Inspect foot valves and check valves, especially the check valve
which safeguards against water hammer when the pump stops. A faulty foot or
check valve will reflect also in poor performance of the pump while in operation.
