Centrifugal Pump Disassembly Instructions

Shut down the centrifugal pump and turn off the electricity flowing to the pump at the breaker. Remove any plumbing pipes or hoses attached to the pump. Cut the plumbing with a PVC hacksaw if PVC plumbing exists.

Unscrew the bolts placed evenly around the pump housing with a wrench. Pull apart the two pieces of the centrifugal pump and set aside the wet portion.

Set a wrench onto the motor's shaft and hold it to keep it from moving. Rotate the pump impeller counterclockwise until it comes off of the shaft.

Pull the ceramic shaft seal carefully off the shaft. Pull the spring portion of the seal out of the back of the impeller.

Unscrew the screws holding the motor armature to the electrical portion of the motor. Pull the entire motor armature out of the motor. Pull the motor bearing off the back of the motor armature.
