Product details
This is the genuine Aqua-Flo 91040820-000 wet end for 1.5 horsepower Flo-Master FMCP pumps. It is the center discharge version, built for a 48Y frame motor with 1-1/2 inch suction and discharge ports.
What a wet end covers
The wet end is everything the water touches: the strainer pot, the volute, the impeller, the diffuser and the seal plate. Buying it as an assembly is the usual answer when the housing itself has cracked or worn past sealing, because it saves stripping the old pump down to individual pieces and it comes matched and true out of the box.
Before you order
Check three things on your existing pump: that it is rated 1.5 horsepower, that the motor nameplate reads 48Y frame, and that the discharge leaves the top center of the volute rather than the side. This wet end is designed for the Flo-Master FMCP and may fit other Aqua-Flo models, so match the part number if your pump carries a different name.
