Operating at reduced capacity:
Warning: DO NOT operate pump below minimum rated flows or with suction and
or discharge valve closed. These conditions may create an explosive hazard due to
vaporization of pumpage and can quickly lead to pump failure and physical injury.
Caution: Damage can occur from:
1. Increased vibration levels – affects bearings and mechanical seal.
2. Increased radial loads – Stresses on shaft and bearings.
3. Heat build-up – Vaporization causing rotating parts to score or seize.
4. Cavitation – Damage to internal surfaces of pump.
Operating under Freezing Conditions.
Exposure to freezing conditions while pump is idle could cause liquid to freeze and
damage the pump. Liquid inside the pump should be drained.
Shutdown
1. Slowly close the discharge valve.
2. Shut down and lock the driver to prevent accidental rotation.
Warning: When handling hazardous and or toxic fluids, proper personal protective
equipment should be worn. If pump is being drained, precautions must be taken to
prevent physical injury. Pumpage must be handled and disposed of in conformance with
applicable environmental regulations.
VI. Maintenance
Overview
This section covers the procedures, precautions and schedule for maintenance of your
Goulds 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
Routine Maintenance
• Bearing lubrication
• Seal monitoring
• Vibration analysis
• Discharge pressure
• Temperature monitoring
