Product Overview

Restore stable flow and predictable motor loading in commercial pool or spa filtration systems with the Pentair 350029Z Impeller Assembly. Manufactured as a direct factory replacement for the Pentair EQ Series, this closed-impeller component is precision-molded from corrosion-resistant PPO resin. When the original casting develops blade erosion, central hub cracks, or flow-degrading obstruction, installing this exact OEM specification returns your pump to its engineered hydraulic curve without altering the drive clearance or impeller profile.

This unit is dimensioned and balanced for 7.5 HP EQ Series electrical configurations. Verify that your pump matches one of the confirmed compatible models before purchasing: EQ750, EQK750, EQKT750, EQK500 (50 Hz), or EQK750 (575V). EQ Series housings vary slightly by manufacture year and regional rating, so cross-checking your manufacturer nameplate or inspecting the cast part number visible inside the existing volute prevents costly compatibility errors.

Installation Protocol
Mounting requires full disassembly of the pump wet end and total electrical lockout. During this service interval, measure the diffuser wear ring, inspect the mechanical shaft seal faces, test O-ring elasticity, and verify mounting bolt threads. Replace any compromised sealing geometry to prevent cavitation once the new impeller is seated. Secure assembly through a licensed commercial pool technician to ensure correct torque sequencing. Pentair backs this replacement component with a standard 1-year general warranty.
