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.<\/p>\n
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.<\/p>\n
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 \u2014 avoiding the vibration, cavitation, and premature seal wear that aftermarket alternatives can cause. Using an authentic Fluidra component also preserves any remaining pump warranty.<\/p>\n
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 \u2014 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.<\/p>","protected":false},"excerpt":{"rendered":"
