Pentair – UltraFlow Plus und SuperFlo Pumpenmotor 2,2 kW, dreiphasig – RP303

Pentair UltraFlow Plus and SuperFlo pump motor 2.2 kW three-phase

This is the genuine OEM replacement motor unit for the Pentair UltraFlow Plus and SuperFlo filtration pump range at the 2.2 kW (3 HP) three-phase rating. It bolts directly onto the existing pump body, restoring the drive assembly to factory specification without replacing the hydraulic end.

Was dieser Motor im UltraFlow Plus leistet

The motor drives the Noryl impeller that circulates pool water through the filtration circuit. Running on a three-phase 380–420 V / 50 Hz supply, it delivers the torque and thermal headroom required for continuous duty on pools where a three-phase electrical installation is available. The IE2-compliant windings meet current European energy-efficiency regulations for this power class, reducing running costs compared with a standard-efficiency replacement.

Für welche UltraFlow Plus- und SuperFlo-Modelle ist es geeignet?

RP303 is confirmed compatible with the UltraFlow (Plus) and SuperFlo pumps at the 2.2 kW three-phase output level, covering model codes P-UFL-301 and P-UFL-303 within the UltraFlow Plus range, as well as the equivalent SuperFlo 3 HP tri-phase variant. Check your existing pump’s nameplate rating — this motor is for three-phase installations only and cannot be connected to a single-phase supply.

Anzeichen dafür, dass es ausgetauscht werden muss

The motor is the most common failure point on a pump that has run for several seasons. Indicators include the pump failing to start or tripping the circuit breaker repeatedly, a loud grinding or humming noise from the motor end (rather than cavitation noise from the hydraulic end), heat marks or a burning smell near the motor casing, and visible play or roughness in the shaft when spun by hand with power disconnected.

Warum Originalprodukte von Pentair wichtig sind

The motor casing, shaft dimensions, and mounting flange on this unit are machined to the same tolerances as the factory-fitted motor, so the pump body’s mechanical seal seats correctly on assembly. An incorrectly dimensioned aftermarket motor shaft causes premature seal failure and immediate water ingress into the motor — a secondary failure that voids any warranty. The Pentair-branded unit ships with the correct shaft length and keyway for the UltraFlow Plus impeller stack.

So installieren Sie es

Motor replacement requires isolating and locking off the three-phase supply at the distribution board before starting work. Remove the quick-release stainless-steel clamp collar joining the motor to the pump body, slide the old motor clear, transfer the mechanical seal if the new unit does not include one, and refit in reverse order. Torque the clamp collar evenly. Electrical reconnection — including correct phase rotation for the direction-of-rotation arrow on the motor casing — must be carried out by a qualified electrician in line with local regulations.
