Fluidra – Sena SS-Pumpenlaufrad 0,75 HP, 50 Hz (vor Mai 2024) – 4405010415

Fluidra – Sena SS Pump Impeller 0.75HP 50Hz (Pre-May 2024)

This is the genuine Fluidra replacement impeller for the Sena SS 0.75HP 50Hz pool pump, compatible with units manufactured before May 2024. The impeller is the rotating core component of the pump’s hydraulic assembly, responsible for drawing water through the pre-filter and propelling it through the pool’s circulation system. Replacing a worn or damaged impeller restores full flow rate and pump efficiency.

Kompatibilität

This impeller is designed exclusively for the Fluidra Sena SS 0.75HP 50Hz pump (Phase II and Phase III variants, models 25463 and 25464) built before May 2024. It is not suitable for 60Hz versions, higher-power Sena SS variants (1HP, 1.25HP), or Sena SS units manufactured from May 2024 onwards, which use a revised impeller design. Always verify your pump’s model number and manufacturing date before ordering.

Warum Echtheit zählt

As an OEM Fluidra part, this impeller is precision-engineered to the exact hydraulic tolerances of the Sena SS pump casing and diffuser. Genuine parts ensure correct water clearance, balanced rotation, and full rated flow — avoiding the vibration, cavitation, and premature seal wear that aftermarket alternatives can cause. Using an authentic Fluidra component also preserves any remaining pump warranty.

Installation

Impeller replacement requires draining and disassembling the pump wet end, including removal of the pump cover, pre-filter basket, and diffuser. The impeller is secured to the motor shaft with a left-hand thread retaining screw — note the reverse-thread direction during removal and refitting. Professional installation by a qualified pool technician is recommended to ensure correct torque and to inspect the mechanical seal at the same time.
