I purchased this pump a few months ago and up until a couple of weeks ago it has been operating smoothly. The pump developed a vibration after a recent maintenance cleaning that I have been unable to determiner the cause. The impeller and bearings looks ok and they were clean. I did notice that the impeller has a lot of slop when seated i.e. a fair amount of side to side movement that may have existed since I purchased the unit new but I didn't notice.
I have a heck of a time getting the front of the pump on the unit as the impeller doesn't sit dead upright in the pump body. In other words in order for me to align the impeller shaft with the bearing on the front removable housing I have to stick a small stick or knife to through the opening in the front pump case to hold the impeller in position so I can seat the housing and bearing over the impeller shaft. I don't remember this when I first took the pump apart.
As I said the bearings are in place and look ok and there doesn't appear to be any damage to the impeller. I do notice and I'm not sure if this is normal but when I turn the impeller over by hand (with the front cover removed) it doesn't rotate smoothly like say my Varios pumps. It is not binding but it just appears to be hung up magnetically i.e. I can rotate it but it just seems to jump to the next position. Whereas with my Varios pump I can just turn it and it rotates smoothly without any magnetic drag. . Any help would be appreciated.
