    Superflow pump problems

    Whatever happened, happened suddenly when the pump was running. Now, it wont pump. The shaft is spinning, and I can hand turn the impeller, but its not moving water. It is making a slight rattling sound, like a loose garbage disposal that is running empty.

    I tried to follow the motor removal instructions, but after taking off the 4 motor bolts, the motor wont come off. It just rotates freely. Its supposed to be 'carefully removed' after taking the 4 bolts off. I'm stuck since taking the whole pump put would involve me cutting pipe.

    Any thoughts?

    You have to remove the other bolts to take the pump apart, those 4 you removed are just to hold the motor onto the seal plate.

    I thought about that, but according to the manual the motor is supposed to slide off when those 4 bolts come off. It wont come off. It just rotates

    The impeller is threaded onto the motor shaft so you have to first take the pump apart and remove it.

    Remove the bolts holding the pump together, remove diffuser and impeller and then the seal plate can be removed from the motor.

    So are the 4 bolts you took off labeled 12/13 in the picture below?



    There is a tight seal which keeps the motor mounting plate sealed to the pump housing. You may have to slowly rock it back and forth to remove.

    My guess is he removed the motor bolts since he said the motor now rotates.

    Success! I have no idea how a 1 inch bolt slipped passed the pump basket, but it did. Impeller threads are stripped. Not as expensive as I thought

    That bolt is probably the impeller lock bolt.

    So it is.

    The impeller itself didn't really thread on to the shaft, cleanly. It seems stripped, but with the lock bolt in it is tight and rotates cleanly with the shaft. I'm thinking I still need a new impeller?

    If the threads are stripped I would replace it for sure.
