Bearing Maintenance - ITT GOULDS PUMPS ICO i-FRAME Installation, Operation And Maintenance Manual

6.4 Bearing maintenance

• 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.
3. Replace worn parts.
6.4 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 repre-
sentative.
