VI. Maintenance
Overview
This section covers the procedures, precautions and schedule for maintenance of your
Goulds Water Technology pump. A routine maintenance program can extend the life of
your pump. Well maintained equipment will last longer and require fewer repairs.
Warnings
Failure to disconnect and lockout electrical power before attempting any
maintenance can cause shock, burns or death.
Failure to relieve system pressure and drain system before attempting any
maintenance can cause property damage, personal injury or death.
If piping is hazardous or toxic fluids, system must be flushed prior to performing
service involving liquid end disassembly.
Maintenance Schedule
Inspection intervals should be shortened appropriately if the pumpage is abrasive or
corrosive, or if the environment is classified as potentially explosive.
Routine Maintenance
• Motor Maintenance
• Seal monitoring
• Vibration analysis
• Discharge pressure
• Temperature monitoring
Routine Inspections
• Check for unusual noise, vibration and bearing temperatures
• Inspect pump and piping for leaks
• Check static seal leakage
• Mechanical seal: should be no leakage
3 Month Inspections
• Check the foundation and hold-down bolts for tightness.
• If the pump has been left idle, check the seal and replace if needed.
Annual Inspections
• Check the pump capacity, pressure and power. If pump performance does not satisfy
your process requirements and the process requirements have not changed, the pump
should be disassembled; inspected and worn parts should be replaced. Otherwise, a
system inspection should be done.
Motor Maintenance
Consult the motor manufacturer’s Installation, Operation, and Maintenance manual
supplied with your motor for proper maintenance procedure and schedule.
