    Which impeller is the right one

    Hello all.

    I am rebuilding the wet side of a Hydramax II http://www.poolzoom.com/leslie-s-hyd...ump-parts.html but have run into a small snag.

    The currently installed impeller is a SPX3007C (3/4 HP "full rate" - 1HP Max). But the motor that is installed is a 1HP motor (AO smith "7-184981-23" - This motor seems like the identical replacement - http://www.inyopools.com/Products/07501352022109.htm

    Should I use the same impeller that is currently installed (not sure if it is factory or was rebuilt by prior homeowner) or should I get the SPX3010C (1 HP "full rate" - 1.5 HP Max)?

    SPX3007C is correct if the total hp is 1.0. Total hp is the label hp x the service factor (S.F).

    The total hp is now labeled on most new motors.

    James.
    Thanks for the quick response. Very informative too. So my motor is 1HP x 1 SF = 1 total. Perfect.

    Thanks again.
