I need a new impeller for my pump - the fins on the inside of the current one are breaking. The problem is that I simply can't figure out what model pump I have. I know it's an old Sta-Rite Max-E-Glas, and I have the label for the motor, but the pump label/plaque is long gone. I've looked everywhere.
The motor is an AO Smith 2.5 HP, SF1.04, 230V, I think it's model 1081.
On Amazon all the C105-137 and one of the C105-138 impellers look like the one I have.
How do I figure out what impeller to get?
