5 WARNING
• 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.
• Never apply heat to impellers.
Failure to follow these directions will result in
serious physical injury.
Close the isolation valves on the suction and discharge sides of the pump.
You must drain the system if no valves are installed. Open the drain valve or plug.
Do not proceed until liquid stops coming out of the drain. If liquid continues to flow from the drain,
the isolation valves are not sealing properly and you must repair them before you proceed.
Leave the drain open. Do not close the drain until the reassembly is complete.
Loosen the volute capscrews but do not remove them.
Shift the pump position slightly in order to allow any pressurized liquid to escape.
Remove the volute capscrews and remove the pump assembly from the volute.
Remove the plug or cover from the motor rear end plate. This will allow access to the end of the motor
shaft. A slot or wrench flats are provided on the end of the shaft to retain the shaft during disassembly
and assembly.
