The Gecko Alliance Impeller 91693601 is a closed-face impeller made specifically for use with the AquaFlo/Gecko FMHP, FMCP, FMVP, and TMCP series pumps. It has an orange dot on the shaft that helps identify it from other models. Rated at 1.0hp, this impeller must be installed on a 1.0hp (or greater) thru bolt motor for maximum performance. The necessary shaft seal is sold separately and must be purchased in addition to the impeller.

The manufacturer altered the rating system for Aquaflo pumps in 2012. Both an operational horsepower (ohp) and a total horsepower (thp) rating have now been given to these pumps. The operational horsepower was all that was used in earlier iterations of these pumps. Make sure to match the operating hp rating rather than the total hp when replacing an older Aquaflo pump.
