Kripsol K-FLO pump impeller / turbine - 3.00 HP - 500100070011

Kripsol K-FLO pump impeller / turbine – 3.00 HP

This is the genuine OEM impeller (turbine) for the Kripsol K-FLO pump at the 3.00 HP rating. It sits at the hydraulic heart of the pump, spinning at speed to draw water through the prefilter basket and push it under pressure into the filtration circuit. Without a correctly matched impeller, the pump cannot deliver its rated flow or head.

What this impeller does in the K-FLO pump

The impeller converts motor rotation into hydraulic energy by accelerating water centrifugally from the inlet eye to the volute discharge. At the 3.00 HP rating this demands a specifically sized and balanced turbine wheel — fitting a lower-rated impeller drops flow dramatically, while a mismatched profile causes cavitation and premature seal failure. This part is machined to the exact blade geometry Kripsol specifies for the 3.00 HP hydraulic stage.

Which Kripsol models it fits

This impeller is designed for the 3.00 HP models within the Kripsol K-FLO pump series, which sits within the broader Koral / Mini Kapri pump family. The K-FLO line covers residential and light-commercial pool installations. Confirm your pump’s HP rating from the motor nameplate before ordering — the impeller profile is not interchangeable across power ratings.

Signs it needs replacing

A worn impeller typically shows as a steady drop in flow rate at unchanged pump speed, rising amperage draw as the motor works harder against inefficient hydraulics, and audible cavitation noise — a rattling or grinding from the pump head. Visible cracks, pitting, or erosion on the blade faces confirm replacement is overdue. If your 3.00 HP K-FLO is running but moving noticeably less water than it should, inspect the impeller before assuming the motor is at fault.

How to install it

Isolate and drain the pump, then remove the prefilter lid and basket to access the volute. Undo the volute retaining bolts and pull the volute clear. The impeller threads or clips directly onto the motor shaft — note the rotation direction and thread type before removal so you reinstall the new one in the correct orientation. Check the shaft seal and O-ring at the same time; replacing them together saves a second disassembly. Reassemble in reverse, refit unions, and prime the pump before restarting.

Why genuine Kripsol matters

Kripsol impellers for this pump family are moulded in Noryl — a glass-fibre-reinforced engineering polymer chosen for its resistance to pool chemicals, salt water, and thermal cycling. Aftermarket copies in standard ABS or unspecified plastic lose their blade geometry through swelling and wear within a season, reducing flow and overloading the motor bearing. The genuine part maintains the hydraulic balance the motor shaft seal was designed for.
