Leaking shaft seal


New member
Mar 14, 2009
Got everything hooked up and looked perfect until i noticed water spraying out of the shaft connecting the motor to the impeller. Dang! I researched on the forum and got a pretty good idea of what i need to do to replace the seals. However my pump is a little different than the ones I saw here (pentair Superflow). I have an older Pentair Dynamo. I cant get the impeller to budge off the shaft went trying to turn in counter-clockwise. I dont see a set screw or anything holding the shaft on. Anyone have experience with this pump? or any advise?
Thanks All!

You may want to use a rubber mallet to gently tap the impeller in the clockwise direction to get it started. The impellers are reverse threaded so in this case it is left to tighten and right to loosen.
