Pentair WhisperFlo Pump Impeller 1.5 HP for WF-6 and WFE-6 | 073129Z

The Pentair 073129Z is a replacement WhisperFlo impeller for 1-1/2 HP full-rated pumps, intended for service and repair of WhisperFlo swimming pool and spa pumps. It fits 1.5 HP full-rated WhisperFlo pumps and is also usable in 2 HP up-rated versions, covering the WF-6, WF-28, WFE-6, WFE-28, WFK-6, WFDS-6 and WFDS-28 models in the Pentair WhisperFlo 1000 Series inground pump line.

The impeller measures approximately 5¼" in length, 2¼" in height and 5¼" in width, and is precision-machined to restore correct hydraulic performance and pressure delivery. Its closed-face design promotes smooth flow and efficient pressure buildup while minimizing turbulence, and correct hydraulic alignment helps reduce vibration, cavitation and stress on the pump seals.

Construction is a corrosion-resistant composite that stands up to pool chemicals and mechanical wear for reliable operation over time. As a drop-in OEM part, it installs without machining or modification.
