Standard Checklist For Pump Maintenance:
The strength and effectiveness of your pump preventive maintenance plan depending on how
robust your checklist is. While you would want to include all possible checks in the plan, it is
impractical and inadvisable for all routine checks. Therefore the checklist is divided based on
the frequency of checks making it more sustainable and effective:
Daily Check:

Check pump exterior for any leaks

Clean pump and nearby region to remove any debris

Check for excessive pump vibration or unusual noises

Check for foaming or oil discolouration

Check bearing temperature for overheating

Inspect all gaskets to ensure there are no oil leaks

Inspect self flush pumps is applicable

Clean bearing covers if needed

Check pump cooling system
Monthly Check:

Top up oil to bearing reservoirs if needed

Clean oil bulbs and level windows

Check the pump guards and replace them if needed

Clear out dirt and debris from bearings and grease them

If applicable, check that the hydraulic governors are working properly

Check overall pump systems for leaks and clean the pumping system surroundings
Quarterly Check:

Check pump and motor for any vibration damage

Grease bearings as per need

Change the oil in bearing systems

Check suction, discharge and head pressure

Check all hold down bolts for tightness to reduce vibration

If needed, inspect shaft pump alignment

Apply rust preventive coat to prevent corrosion
Annual Check:

Check axial float of the pump along with the driver shaft

Remove mechanical cover and inspect the entire pump arrangement

Check disc couplings for damage

Inspect coupling alignment

Perform the Overspeed test for the pump

Inspect seal chamber for scoring and pitting

Check oil levels and refill as per need

Inspect impeller for erosion and replace if needed
Please note that the pump preventive maintenance schedule for each pump would depend
on its design and application, and hence you should always consult the pump manufacturer
for the same. However, the above checklist is a general checklist that can guide the process
of pump preventive maintenance. A well-maintained pump will last longer and perform better
than one not correctly cared for.
