Fluidra - Replacement Impeller for Sena SS 0.33 HP Single-Phase 50 Hz Pump (from May 2024) - 4405011442

Fluidra – Replacement Impeller for Sena SS 0.33 HP Single-Phase 50 Hz Pump (from May 2024)

This is the genuine Fluidra replacement impeller for the AstralPool Sena SS 0.33 HP single-phase (230 V, 50 Hz) self-priming pool pump, compatible with units manufactured from May 2024 onwards. The impeller is the rotating component at the heart of the pump’s hydraulic stage, responsible for drawing water from the pool and pushing it through the filtration circuit with the correct flow and pressure.

Compatibility

This impeller is designed exclusively for the Sena SS 0.33 HP single-phase 50 Hz pump (model reference PUMP SENA SS 0.33HP 50HZ II) produced from May 2024. The Sena range covers power ratings from 1/3 HP to 1.25 HP in single-phase versions, and Fluidra periodically updates internal hydraulic components between production batches — always verify your pump’s manufacturing date before ordering to ensure the correct impeller is selected.

Why Genuine Matters

The Sena SS pump is engineered with NORYL impellers and AISI-316 stainless steel hardware for all water-contact components, delivering reliable hydraulic performance and corrosion resistance in pool water. Using a genuine Fluidra impeller ensures the original hydraulic balance, correct clearances within the pump body and diffuser, and compliance with the pump’s rated flow output — non-genuine parts risk reduced flow, increased motor load, and premature wear.

Installation

Replacing the impeller requires partial disassembly of the pump’s wet end, including removal of the pump body and mechanical seal assembly. The pump must be fully isolated from the power supply and the water circuit drained before work begins. Professional installation by a qualified pool technician is recommended to ensure correct torque, seal integrity, and safe recommissioning.
