Disassembly
Disassembly precautions
WARNING:
• This manual clearly identifies accepted methods for disassembling units. These methods must be
adhered to. Trapped liquid can rapidly expand and result in a violent explosion and injury. Never apply
heat to impellers, propellers, or their retaining devices to aid in their removal.
• Make sure that the pump is isolated from the system and that pressure is relieved before you
disassemble the pump, remove plugs, open vent or drain valves, or disconnect the piping.
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical
injury.
• Crush hazard. The unit and the components can be heavy. Use proper lifting methods and wear steel-
toed shoes at all times.
• The pump can handle hazardous and toxic fluids. Identify the contents of the pump and observe
proper decontamination procedures in order to eliminate the possible exposure to any hazardous or
toxic fluids. Wear the proper personal protective equipment. Potential hazards include, but are not
limited to, high temperature, flammable, acidic, caustic, explosive, and other risks. You must handle
and dispose of pumped fluid in compliance with the applicable environmental regulations.
NOTICE:
Make sure that all replacement parts are available before you disassemble the pump for overhaul.
