KSE made a pump commonly refered to as the "Black" pump because of the black anodizing on part of it. The Black pump was a pump that could be reversed.
The newer KSE pump is refered to as the "Blue" pump because of it's anodizing color. While that pump is a higher flow pump, it cannot be reversed.
Why the pump has to be reversed is because the cam shaft direction in a Fonatana is different than a Gearte.
If you have any problems finding a pump, email me a
leadersedge@earthlink.net and maybe I can help. If you already have a black pump and all it needs is reversed, and you are not sure how to do it, feel free to email as well.
