Bearing maintenance
These bearing lubrication sections list different temperatures of pumped fluid. If your pump is ATEX
certified and the pumped fluid exceeds the permitted temperature values, then consult your ITT
representative.
Bearing lubrication schedule
Type of bearing First lubrication Lubrication intervals
Oil-lubricated bearings Add oil before you install and start
the pump.
Change the oil after 200-300 hours
of operation, depending on
bearing temperature.
See the Oil change schedule table.
Grease-lubricated bearings N/A Every 4000 hours of operation or
once a year, whichever comes first
Every two years if the pump is left
idle
Oil change schedule
Oil must be changed at least once a year.
Bearing temperature First oil change Subsequent oil changes
Up to 140°F (60°C) After 300 hours of operation Every 8760 hours of operation
140°F to 176°F (60°C to 80°C) After 300 hours of operation Every 4000 hours of operation
176°F to 212°F (80°C to 100°C) After 200 hours of operation Every 3000 hours of operation
NOTICE:
• Strictly maintain the oil changing schedule if the pump is operating in an potentially explosive
environment.
• Change the oil every two years if the pump is left idle.
• Dispose of used oil in accordance with local environmental regulations.
