I'm having a problem with a chugger pump I just purchased. It has brand new and I was trying to get it up and running last night. It was originally shipped with a plastic head and this seems to work fine and everything moves as it should. I also received a SS head that will not allow the motor to turn. It essentially just sits there and and the fan pulses and looks like it like it wants to move but is stuck. I took the head apart multiple times and the impeller spins just fine by hand. There are no obstructions to the impeller and everything works just fine otherwise unless the impeller is in place.
The only thing I can think is that the backplate that holds the impeller in place does not fit very well and could be causing too much friction between it and the impeller and not allowing the magnetic drive magnet and motor to turn. Everything else is very functional and this seems to be the limiting factor.
I have seen threads with this type of problem for march pumps but they were found to have obstructions or stuck impellers because of improper cleaning.
