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.
6.2 Bearing maintenance
Lubrication schedule
Type of bearing First lubrication
Lubrication intervals
Oil lubricated
Change the oil after 200 hours for
new bearings.
After the first 200 hours, change the oil every 4000 operat-
ing hours or every six months.
For ATEX applications bearing replacement (all) is recommended after 17,500 hours of oper-
ation.
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.
6.3 Disassembly
6.3.1 Disassembly precautions
WARNING:
•
Chemical hazard. You must individually decontaminate each component according to all
federal, state, local, and company environmental regulations.
•
A build up of gases within the pump, sealing system, or process-piping system can result
in an explosive environment within the pump. Make sure that the process piping system,
pump, and sealing system are properly vented prior to operation.
•
Burn Hazard. Coupling may be hot. Use proper protection when handling.
•
Burn Hazard. use proper protection when handling bearings.
•
Avoid injury. Worn pump components can have sharp edges. Wear appropriate gloves
while handling these parts.
•
Risk of serious personal injury from exposure to hazardous or toxic liquids. A small
amount of liquid will be present in certain areas like the seal chamber upon disassembly.
•
Process fluid leaks can result in an explosive atmosphere. Follow all pump and seal as-
sembly procedures.
•
Risk of serious personal injury. Applying heat to impellers, propellers, or their retaining
devices can cause trapped liquid to rapidly expand and result in a violent explosion. This
manual clearly identifies accepted methods for disassembling units. These methods must
be adhered to. Never apply heat to aid in their removal unless explicitly stated in this
manual.
