I am having trouble finding a replacement part for a Dayton utility pump. The model # is: 9m751, the Hp is: 1/40, the Hz is: 60, Class: A. This pump also has a small fan at the bottom to stir the Aluminum Sulfate. I have been having a lot of trouble finding this part. The main part I need is the fan, because it got rusted and fell off. Let me know if there are any websites where I can find this part. Any help is really appreciated. Thanks again!
