Product details

The Pentair 075455 is the WFE-8 fluid end for the 2 HP WhisperFlo pool pump. Pentair lists it as all of the pump parts without the motor, which makes it the entire wet end of the pump under a single part number.

What the wet end covers

The wet end is the side of the pump that water passes through. On a WhisperFlo that is the strainer pot with its lid and basket, the diffuser, the impeller and the seal plate with its mechanical seal. When the housing has cracked, or several of those parts are worn at the same time, fitting a complete fluid end to the motor is one job instead of several.

Before you order

Check that the pump label reads WFE-8. Pentair builds a separate fluid end for each WhisperFlo size, from the 3/4 HP WFE-3 through the 3 HP WFE-12. For the WFE-8, Pentair lists 355014S as the 2 HP single speed motor, and the impeller on its own is part 073130 if that is the only part that has failed. WhisperFlo pumps connect through 2 in. NPT suction and discharge ports.
