Description

The Pentair 073126 impeller is a performance-critical component for WhisperFlo ½ HP (and uprated ¾ HP) models including WF-2, WF-23, WFE-2, and WFK-2. Its job is to push water through the pump system efficiently: if the impeller is chipped, worn, clogged, or damaged, flow and pressure drop, reducing overall pump effectiveness. Replacing with a new OEM 073126 restores optimal flow, reduces motor load, and helps maintain proper filtration and circulation for your pool.

Pro Tip

When replacing the impeller, also inspect the volute or diffuser housing for scoring or wear. Replace worn components like the volute gasket or shaft seal to avoid leaks or air suction.

Installation Tips

Turn off power and relieve any system pressure before opening pump. Clean debris from housing and impeller cavity so new impeller sits cleanly. Confirm pump model matches impeller part number. Tighten impeller retaining hardware to torque specs—not over-tightening.
