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 environment 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 that there is no leakage from the mechanical seal.
Three-month inspections
Perform these tasks every three months:
• Check that the foundation and the hold-down bolts are tight.
• Check the mechanical seal if the pump has been left idle, and replace as required.
• Change the oil every three months (2000 operating hours) at minimum.
• Change the oil more often if there are adverse atmospheric or other conditions that
might contaminate or break down the oil.
• 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.
3. Replace worn parts.
