Pentair – UltraFlow Plus járókerék 1,50 kW – R39005400

Pentair UltraFlow Plus impeller 1.50 kW

This is the genuine OEM impeller for the 1.50 kW variant of the Pentair UltraFlow Plus pool pump — the rotating hydraulic component that draws water through the pre-filter basket and forces it out to the filtration circuit. Part number R39005400 is listed directly in the Pentair UltraFlow Plus spare-parts catalogue as position 4, the single impeller for the 1.50 kW power rating.

Milyen szerepet tölt be ez a járókerék az UltraFlow Plus készülékben?

The impeller is the heart of the pump’s hydraulic end. Mounted on the motor shaft behind the seal plate, it spins at motor speed to generate the pressure differential that moves pool water through the filtration system. A worn or cracked impeller reduces flow rate, cuts hydraulic head, and forces the motor to run hotter — replacing it restores the pump to its rated output without touching the motor or volute.

Mely UltraFlow Plus modellekhez illeszkedik?

R39005400 fits all UltraFlow Plus pump models equipped with the 1.50 kW motor, covering both single-phase and three-phase variants. Confirmed compatible model codes include P-UFL-201 and P-UFL-203. Cross-reference your pump’s nameplate power rating — this impeller is specific to the 1.50 kW hydraulic end and is not interchangeable with the 0.55 kW, 0.75 kW, 1.10 kW, or 2.20 kW impellers listed separately in the same parts diagram.

Jelek, amelyek arra utalnak, hogy cserére szorul

Noticeable drop in flow rate despite a clean basket and clear pipework is the first indicator. You may also hear a change in pump tone — a rougher, less even note as the damaged vanes cavitate under load. Visible hairline cracks on the vane edges, or fragments of plastic found in the pre-filter basket after a service, confirm the impeller has reached the end of its service life.

Hogyan kell telepíteni?

Isolate the pump from the electrical supply and close both inlet and outlet valves before opening the pump. Release the stainless-steel band clamp to separate the power end from the volute, then remove the seal plate (R39004910) to access the impeller. Unscrew the impeller from the shaft — note it is reverse-threaded on some variants, so turn clockwise to loosen. Fit the new impeller finger-tight, reassemble in reverse order, and check for leaks on first start-up. The job typically takes 20–30 minutes with a flat-blade screwdriver and a strap wrench.
