Genuine replacement impeller designed for Aqua-Flo XP2 and FMXP2 wet end assemblies. This 2.5 horsepower impeller features precise dimensions: 2 1/8 inch eye diameter, 5/16 inch vane width, and 4 inch outer diameter. Engineered specifically for 48 or 56 frame wet ends paired with 2.5HP motors drawing approximately 11.0 amps at high speed operation.

Critical Installation Details: The impeller mounts between the face plate and volute housing of your Aqua-Flo wet end. We strongly recommend replacing the PS-200 seal simultaneously with impeller replacement for optimal performance and longevity.

Frame Identification Guide: 48 frame wet ends measure 3 5/8 inches between motor through-bolts (5 3/16 inches in X pattern) with 1/4 inch bolt heads. 56 frame models measure 4 1/8 inches between bolts (5 3/4 inches in X pattern) with 5/16 inch bolt heads.

Important Sizing Warning: Never install a larger impeller than specified for your motor. Oversizing causes motor overheating and damage during high-speed operation. Use the amperage chart to verify correct horsepower: 115V motors with 1HP impellers draw 11-12.0 amps on high; 230V motors draw approximately 8.0 amps on high.
