Seal and O-ring compatibility check

Verify that the existing pump housing accepts the B2848 frame and shaft dimensions before ordering. Confirm the seal plate, diffuser, impeller and lid grooves match the supplied O-ring sizes. The kit includes O-rings numbered 108, 186, 304, 318, 359 and gasket 413 for a complete reseal.

GO-KIT-32 seal package impact

Questions about this item

Does the kit include every O-ring and seal needed for the motor swap, or must any gasket be purchased separately?

The GO-KIT-32 bundles O-304, O-359, O-186, O-108, O-318 and G-413, covering the seal plate, diffuser, impeller and lid interfaces so no extra gaskets are required.

What distinguishes the B2848 motor from other Whisperflo replacements listed in the catalogue?

The B2848 is an AO Smith 1 HP unit built for the WF-4 frame; the accompanying GO-KIT-32 adds the full O-ring set, making it a direct drop-in kit rather than a bare motor.

Once installed, what does the 1 HP rating actually deliver on a typical residential pool circuit?

The 1 HP AO Smith motor restores the original Whisperflo WF-4 flow curve, providing the same turnover rate the pump was designed for when it left the factory in 2022.
