Maintenance Schedule
NOTES:
1. Inspect and perform maintenance periodically according to the maintenance schedule.
2.
The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition are adverse, shorten the
cycle time and perform maintenance accordingly.
3. Belts require no attention unless slippage is detected (Chirping sound on start up or while running). Re-tension as indicated when tip
seals are replaced for the first time. Proper belt tension should be 0.25 inch deflection when 6 pounds of force is applied on the center
of the belt span.
4. If the pumps reach 4 years and have not yet accumulated 5,000 hours, perform the greasing operation for the bearings, with the number
of pumps reduced by 25%. (See details of pump grease operation.) Tip seals do not require early replacement, but must be done before
or at 5,000 hours of run time.
