Fluidra - Replacement Impeller for Sena SS Pump 0.5 HP 50 Hz (from May 2024) - 4405011444

Fluidra – Replacement Impeller for Sena SS Pump 0.5 HP 50 Hz (from May 2024)

This is the genuine Fluidra replacement impeller for the Sena SS single-phase pool pump rated at 0.5 HP and 50 Hz. Introduced as a revised component for pumps manufactured from May 2024 onwards, it is the rotating element at the heart of the pump’s hydraulic assembly, responsible for drawing water in and propelling it through the filtration circuit. Fitting only the correct power-rated impeller ensures the pump operates at its designed flow and head performance.

Compatibility

This impeller is designed exclusively for the Fluidra AstralPool Sena SS 0.50 HP single-phase (II) pump running at 50 Hz, for units built from May 2024 onwards. It is not interchangeable with impellers from earlier production runs or other Sena power variants such as the 0.75 HP or 1.25 HP models. Always verify your pump’s nameplate data and production date before ordering.

Why Genuine Matters

As a genuine Fluidra spare part, this impeller is manufactured to the exact tolerances of the original component, ensuring correct hydraulic balance and long service life. The Sena range is engineered with an impeller made of NORYL®, a high-performance engineering thermoplastic chosen for its dimensional stability and resistance to pool chemicals including saltwater. Using a non-genuine substitute risks reduced flow rates, premature wear, and potential motor overload.

Installation

Replacing the impeller requires draining and disassembling the pump’s wet end. The impeller must be seated correctly on the motor shaft and tightened to the manufacturer’s specified torque before reassembly. While an experienced pool technician can complete this service, those less familiar with pump internals are advised to have the work carried out by a qualified professional to avoid damage to the mechanical seal or pump body.
