• 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.
Bearing maintenance
These bearing lubrication sections list different temperatures of the pumped fluid. If the
pump is ATEX-certified and the temperature of 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 hours for new bearings. After the first 200 hours, change
the oil every 1000 operating hours
or every two months.
Grease-lubricated bearings Grease-lubricated bearings are in-
itially lubricated at the factory. Regrease bearings every 500 op-
erating hours or every month.
Lubricating oil requirements
Use a high quality turbine oil with rust and oxidation inhibitors.
You can use an oil of ISO viscosity grade VG 220 (SAE grade 50W) for all bearing operation
temperature ranges.
