Routine maintenance
Perform these tasks whenever you perform routine maintenance:
•
Lubricate the bearings.
•
Inspect the seal.
•
Perform a vibration analysis.
•
Monitor the discharge pressure.
•
Monitor the temperature.
Routine inspections
Perform these tasks whenever you check the pump during routine inspections:
•
Check the level and condition of the oil through the sight glass on the bearing frame.
•
Check for unusual noise vibration, and bearing temperatures.
•
Check the pump and piping for leaks.
•
Analyze the vibration.
•
Check the seal chamber and stuffing box for leaks.
•
Ensure that there are no leaks from the mechanical seal.
•
Adjust or replace the packing in the stuffing box if you notice excessive leaking. Refer to
"packing gland adjustment".
Three-month inspections
Perform these tasks every three months:
•
Check that the foundation and the hold-down bolts are tight.
•
Check the packing if the pump has been left idle, and replace as required.
•
Change the oil every three months (2000 operating hours) at minimum.
•
If any rubbing noise has been noticed, re-align the impeller.
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.
WARNING:
A worn propeller and/or pump housing can have very sharp edges. Wear protective gloves.
