Product Overview

Restore precise hydraulic flow to your commercial pool system with the Pentair 350030Z Impeller Assembly, a genuine OEM replacement engineered exclusively for select 5 HP EQ Series pumps. Constructed from impact-resistant PPO resin, this closed-style impeller directly replaces worn or damaged units without requiring modifications to the pump housing or existing plumbing layout.

Maintaining the exact blade geometry and clearance specified for closed-impeller designs, this component reduces motor loading and prevents cavitation under continuous commercial duty cycles. It secures to the factory drive shaft via a standard key and locking screw, delivering balanced rotation that extends mechanical seal and bearing life. Unlike unverified aftermarket alternatives, the 350030Z meets Pentair’s original manufacturing tolerances for reliable water circulation and thermal management in high-volume spa and public pool applications.

Specifications

Warranty & Compatibility

This impeller fits specific configurations within the EQ lineup, including EQ500, EQK500, EQKT500, and EQK300 models. Because not every 5 HP EQ Series pump shares the same internal impeller design—some alternate configurations require part numbers like 350070Z or 350029Z—always verify your equipment’s model plate and existing impeller imprint before purchasing. Ships weighing 0.85 lb with compact dimensions of 5 x 5 x 2.25 in., and includes a 1-year general warranty. Professional installation by a licensed pool service technician is recommended to ensure proper wet-end assembly and optimal shaft alignment upon return to service.
