Fluidra – Impeller 1.25 HP for Sena SS Pump (Three-Phase, 60 Hz) – from May 2024

This is the genuine Fluidra replacement impeller for the Sena SS self-priming pool pump at 1.25 HP, three-phase, 60 Hz. The impeller is the core rotating component responsible for generating water flow through the pump, and replacing a worn or damaged impeller restores the pump’s hydraulic performance to its original specification.

Compatibility

This impeller is designed specifically for the Fluidra Sena SS 1.25 HP three-phase 60 Hz pump (parent model 25468-0810) built from May 2024 onwards. It is not interchangeable with earlier production units or with single-phase, 50 Hz, or lower-horsepower Sena variants — always verify your pump’s manufacturing date and model code before ordering.

Why Genuine Matters

The Sena SS pump uses AISI-316 stainless steel wetted components and operates at 3,000 rpm, so hydraulic balance and material integrity are critical. A genuine Fluidra impeller is precision-engineered to match the exact bore, vane geometry, and balance tolerances of the original, ensuring reliable flow rates, correct shaft loading, and a proper fit with the existing diffuser and pump body.

Installation

Impeller replacement requires draining the pump, disassembling the pump housing, and correctly torquing the impeller onto the motor shaft. The task is straightforward for a qualified pool technician but is best left to a professional to avoid damage to the mechanical seal or motor bearings. Always replace the mechanical seal at the same time for best results.
