Maintenance inspections
A maintenance schedule includes these types of inspections:
•
Routine inspections
•
Three-month inspections
•
Annual inspections
Shorten the inspection intervals appropriately if the pumped fluid is abrasive or corrosive or if the envi-
ronment is classified as potentially explosive.
Routine inspections
Perform these tasks whenever you check the pump during routine inspections:
•
Check for unusual noise vibration, and bearing temperatures.
•
Check the pump and piping for leaks.
•
Analyze the vibration.*
NOTICE:
*If equipped, temperature and vibration levels can be retrieved by using your i-ALERT monitor-
ing sensor and app.
Three-month inspections
Perform these tasks every three months:
•
Check that the foundation and the hold-down bolts are tight.
Annual inspections
Perform these inspections one time each year:
•
Check the pump capacity.
•
Check the pump pressure.
•
Check the pump power.
If the pump performance does not satisfy your process requirements, and the process requirements
have not changed, then perform these steps:
1.
Disassemble the pump.
2.
Inspect it.
3.
Replace worn parts.
