Kripsol - K-FLO pump impeller/turbine 0.50 HP - 500100070007

Kripsol K-FLO pump impeller/turbine 0.50 HP

This is the genuine OEM impeller (turbine) for the 0.50 HP variant of the Kripsol K-FLO pump series, which shares its hydraulic architecture with the Koral KS and KSE family. The impeller is the rotating core of the pump’s wet end: it converts motor torque into flow, drawing water through the pre-filter and forcing it through the diffuser toward the filter circuit. Without a fully intact impeller, the pump loses head pressure, flow drops, and the pool filtration cycle stalls.

Rôle de cette roue dans la pompe K-FLO

Mounted directly on the motor shaft, the impeller spins at 2,850 RPM to generate the centrifugal force that drives water through the hydraulic body. At 0.50 HP, it is sized to deliver the correct flow curve for small-to-medium residential pools — replace it with a non-spec impeller and you shift that curve, either starving the filter or over-pressurising it. The Noryl construction resists the chlorine concentrations and salt-chlorination chemistry found in everyday pool water.

Avec quels modèles K-FLO et Koral est-il compatible ?

This impeller is specific to the 0.50 HP (½ CV) output rating within the K-FLO pump series. The K-FLO range is the Hayward-badged equivalent of the Kripsol Koral KS/KSE hydraulic platform; seal kits, diffusers, and impellers are shared across both lineages at the same power rating. Confirm your pump’s nameplate reads 0.50 HP / 0.37 kW before ordering — impellers for other HP ratings in the same series are not interchangeable.

Signes indiquant qu'il faut le remplacer

A worn or cracked impeller typically presents as a sudden drop in return-jet velocity with the motor running normally, or an audible change in pump tone — from a smooth hum to an irregular cavitation rattle. You may also see the pressure gauge on the filter tank reading lower than its baseline while the pump draws the same current as before. Debris ingested past a failed basket commonly scores the impeller vanes, causing progressive flow loss rather than an abrupt stop.

Pourquoi il est important d'appliquer fidèlement le principe « Kripsol »

The impeller’s vane geometry, bore diameter, and shaft-fit tolerance are machined to OEM specification; aftermarket alternatives regularly ship with looser bore tolerances that allow micro-play on the shaft, accelerating wear on the mechanical seal and motor bearing. Fitting a genuine Kripsol part preserves the designed hydraulic balance and protects the motor warranty where applicable.
