APPENDIX A – MAINTENANCE TIMETABLE
DAILY MAINTENANCE
1. Check bearing temperature. Use an instrument such as a thermometer, surface
pyrometer or Infrared thermometer. Do not use your hand. Temperature must be
below 180˚ F.
2. Check suction and discharge pressures.
3. Check shaft packing for excessive leakage.
THREE MONTH MAINTENANCE
1. Grease bearings per instructions in Section 4, Page 9.
2. Check grease that comes out relief plug. If white it indicates water
contamination. Remove contaminated grease, replace with new grease.
SIX MONTH MAINTENANCE
1. Check packing and replace, if necessary. Be sure lantern ring is centered in the
stuffing box and seal water piping is in good condition.
2. Take vibration readings and compare to previous readings.
3. Check shaft sleeve, if grooved/worn; replace. (If not replaced when worn,
packing life will be reduced.)
YEARLY MAINTENANCE
1. Depending on the fluid pumped and pump operating hours during the year, check
pump performance and vibration inspection records. If necessary remove the
Front Plate(31) and Liner(30) then inspect Casing halves, Impeller and Liners.
These inspections can range from once a year, to once every three to five years.
