Retro Gen 1 - 140mm Impeller

The only impeller designed to work with the 550 / 750 pump conversion. There are many impellers on the market that are designed to have a larger motor in front of them. Like most, we made due with impellers that sorta worked with tweaks but it was always a compromise. This impellers is designed and cast with the 550 motor in mind and has been tested against all other impellers either reshaped, re-cut, or re-bent.
