Remove the coupling
1. Loosen the setscrews in both coupling halves.
2. Slide each half as far back as possible on the shaft.
3. Remove the sleeve.
If you use a full-diameter impeller, you might have to remove the pump-side coupler half
and slide the motor back on its base. This allows you to gain sufficient clearance in order
to remove the pump assembly from the volute.
Remove the bearing frame and impeller assembly
1. Remove the support foot capscrews.
2. Loosen the volute capscrews but do not remove them.
3. Use the capscrews in the jackscrew holes.
4. Loosen the bearing frame and impeller assembly from the volute.
WARNING:
Make certain that the internal pressure of the pump is relieved before
you continue. Failure to follow these instructions could result in serious
personal injury or death, or property damage.
5. Remove the seal flush piping if it is used.
