6.1 Maintenance schedule
Maintenance inspections
A maintenance schedule includes these types of inspections:
• Routine maintenance
• Routine inspections
• Three-month inspections
• Annual inspections
Shorten the inspection intervals appropriately if the pumped fluid is abrasive or corrosive or if the en-
vironment is classified as potentially explosive.
Routine maintenance
Perform these tasks whenever you perform routine maintenance:
• Lubricate the bearings.
• Inspect the seal.
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.
• Inspect the discharge pressure.
• Inspect the temperature.
• 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.
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.
• Check the shaft alignment, and realign as required.
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.
