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. For standard pressure pumps (116 psig), if the pumps reach 4 years and have not yet accumulated 10,000
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
10,000 hours of run time for standard pressure pumps or 5,000 hours of run time for high pressure pumps.
For high pressure pumps (145 psig), if the pumps reach 2 years and have not yet accumulated 5,000 hours,
perform the greasing operation for the bearings, with the number of pumps reduced by 25%.
