This is the genuine OEM impeller (turbine) for the 1.00 HP variant of the Kripsol K-FLO pool filtration pump. The impeller is the rotating hydraulic core of the pump: it accelerates water from the inlet, builds pressure, and drives flow through the filtration circuit at the rated 1.00 HP duty point. Without a serviceable impeller, the pump loses prime, drops flow and ultimately fails to turn over the pool volume.<\/p>\n
The impeller converts motor shaft rotation into hydraulic pressure, drawing water from the pool through the pre-filter basket and pushing it at pressure through the filter and back to the returns. The K-FLO uses a closed-vane Noryl impeller moulded with a stainless-steel core insert, a pairing that gives the component its chemical and mechanical resilience in both chlorinated and salt-water pools. A worn or cracked impeller erodes flow rate before it causes an obvious breakdown, so output loss is often the first symptom you will see.<\/p>\n
This impeller is specific to the 1.00 HP (0.75 kW) build of the K-FLO pump series \u2014 the Kripsol \/ Hayward K-FLO platform shares its hydraulic architecture with the Koral KS and KSE Koral family, and the K-FLO is a recognised direct successor to those pumps. The 1.00 HP size uses \u00d8 50 mm pipe connections; verify your pump’s HP rating and connection diameter before ordering, as each power rating uses a dimensionally distinct impeller.<\/p>\n
Watch for a sustained drop in filter pressure (gauge reading below normal operating range), reduced return-jet velocity, the pump struggling to prime after seasonal start-up, or a grinding\/rattling noise from the volute chamber \u2014 all point to an impeller that is either worn at the vane tips, cracked, or has a loose stainless-steel core insert. Cavitation damage typically shows as pitting across the vane faces.<\/p>\n
Shut off the pump, isolate the circuit valves, and drain the pump casing. Remove the pre-filter lid and basket, unbolt the pump body from the motor, and unscrew the impeller from the motor shaft (left-hand thread on most Koral-platform units \u2014 rotate clockwise to loosen when facing the shaft end). Seat the new impeller hand-tight, then snug it a quarter-turn further; overtightening risks cracking the Noryl hub. Reassemble in reverse, re-prime, and check for pressure recovery before returning the system to service.<\/p>\n
The Noryl impeller vane geometry, core insert diameter, and shaft-thread pitch are tolerance-matched to the K-FLO diffuser housing. Aftermarket impellers in this power class frequently differ in vane count or hub depth, producing cavitation noise or reduced head that is difficult to diagnose as a parts issue rather than a motor or installation fault. A genuine Kripsol part restores the pump to its rated hydraulic curve without guesswork.<\/p>","protected":false},"excerpt":{"rendered":"
