Description

The Pentair IntelliFloXF / WhisperFloXF Pump Impeller Screw (356073) is a genuine OEM fastener used to secure the pump impeller to the motor shaft inside XF-series variable speed pumps. This metal-head screw is designed for pump models manufactured after October 7, 2019, and replaces earlier plastic-head versions used on older pumps.

The screw prevents the impeller from loosening during operation, ensuring proper rotation and maintaining the pump’s hydraulic performance. While small, this part is essential for safe and reliable pump operation.

During pump service, the impeller screw is removed to allow access to the impeller and shaft seal assembly. Using the correct Pentair replacement hardware ensures proper fit and helps prevent damage to the motor shaft or impeller hub.

Pro Tip

If you're replacing the impeller screw during a pump repair, it's a good idea to inspect the shaft seal and diffuser O-ring at the same time. These components often wear together and are commonly replaced during XF pump rebuilds.

Installation Tips

Disconnect the power before servicing the pump. When removing the impeller screw, hold the motor shaft from the rear of the motor and loosen the screw with the correct socket. Always verify compatibility with XF-series pumps manufactured after October 7, 2019.
