Other compatible alternatives are identified in the individual product listing. Please review the listed specifications, fitment details, and any installation differences before ordering.

Please note: When you have a seal leaking in most cases you will need an impeller because the leak caused water to get into the metal shaft area that the impeller is screwed onto and expands and damages the impeller. We offer the impellers along with the seal in a kit in our store. Watch the video above for how to install the seal and other repairs for this pump as well.
