This genuine replacement impeller is engineered for Aqua-Flo XP2 and FMXP2 wet end assemblies equipped with 1.5 horsepower motors running at approximately 9.0 amps on 230 volt systems or 14.0 amps on 115 volt configurations. The impeller features precise measurements including a 2 1/8 inch eye diameter, 5/16 inch vane width, and 4 inch outer diameter, ensuring optimal water flow performance in your spa circulation system.
Key Specifications:
- Horsepower Rating: 1.5HP
- Eye Diameter: 2 1/8 inches
- Vane Width: 5/16 inches
- Outer Diameter: 4 inches
- Electrical: 230V/9A or 115V/14A
- Manufacturer Part Number: 91694150
- Compatible with 48 and 56 frame wet ends
This component installs between the face plate and volute housing of compatible Aqua-Flo pump assemblies. When performing impeller replacement, we strongly recommend installing a new PS-200 mechanical seal simultaneously to maintain proper pump operation and prevent leakage.
Frame Compatibility Guide: The 48 frame configuration features motor through-bolt spacing of 3 5/8 inches between bolts (5 3/16 inches in X-pattern) with 1/4 inch bolt heads. The 56 frame version has 4 1/8 inch spacing between bolts (5 3/4 inches in X-pattern) with 5/16 inch bolt heads.
Important Amperage Reference: For 115V motors, a 1HP impeller typically draws 11-12.0 amps at high speed, while 230V motors draw approximately 8.0 amps. Always verify your motor's amperage rating before selecting replacement impellers. Installing an oversized impeller will cause motor overheating and potential damage rather than improved performance. Match your replacement impeller to your motor's actual horsepower rating for safe, efficient operation.
