About This Item
The Pentair Power End (400619Z) is the OEM replacement motor and mechanical drive assembly for the WhisperFlo XF / MAX-E-PROXF series inground pump line, rated at 5 horsepower with 3-phase, 208-230-460V operation.
The power end houses the motor, motor bracket, and shaft assembly that drives the pump's wet end impeller. When bearing wear, winding failure, or shaft damage makes motor replacement necessary, swapping the complete power end restores full pump output without requiring replacement of the hydraulic wet end components.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.
Pro Tip
A 3-phase power end requires a confirmed 3-phase power supply at the installation site — this unit is not compatible with standard single-phase residential service. Before ordering, verify your pump's existing motor nameplate matches the 5HP / 3-phase / 208-230-460V specification. The model suffix on your pump (e.g., XFK-20) identifies the frame size and hydraulic configuration; confirm it appears in the Fits Into table above to ensure the power end interfaces correctly with your existing wet end. Installation and electrical connection of this component must be performed by a licensed electrician or certified pool technician.
