One Note for almost all Magnetic drive pumps. If the shaft isn't centered exactly so the gap between the epoxy sealed coil and the magnetic core, the thing will have problems restarting. So when taking apart make sure the shaft at each end in inserted into it's mating bushing properly, And centered. Take your time in doing this and you will have less problems with even the Rio's. No matter how much current running through them, if the spacing isn't right it will just pull the magnetic core to one side and it will stay stationary. Now that is the major difference between them and most external pumps, the motor on externals only uses fixed bearings/bushings and brushes, that can be replaced on the better models. Instead of an Impeller like the Magnetic drives, you have a true Impeller pump, these motors produce more torque and can push heaver loads than the mages & will start every time unless the brushes are burnt, in general!
