Hi all! I just rebuilt my pump new bearings, seals, and grease. Everything is back together correctly i triple checked. The problem im having is one blade on the impeller keeps rubbing the stator after closer inspection i was spinning the impeller slowly with a wrench i notice something looks bent. Im wondering if it can only be the stub shaft? Or could the impeller be bent? I took off the impeller and spun the stub shaft by itself i just cant tell for sure. Thanks!
