Pentair - Motor de bomba UltraFlow Plus trifásico de 1,10 kW - RP153

Pentair UltraFlow Plus pump motor 1.10 kW three-phase

This is the genuine Pentair replacement motor unit rated at 1.10 kW (1.5 HP) for three-phase (400 V) installation, designed to bolt directly onto the UltraFlow Plus hydraulic end. It is the component that drives the impeller and delivers the pump’s rated flow; when the motor fails, this is the part you replace rather than the entire pump assembly.

Qué hace este motor en el UltraFlow Plus

The motor converts three-phase electrical power into rotational torque that spins the impeller inside the pump volute. The asynchronous induction design runs at a fixed synchronous speed, producing the steady, continuous flow required for pool filtration circuits. Because it is a three-phase unit, it draws balanced current across all three phases and operates without a run capacitor — the torque characteristics are inherently superior to a single-phase equivalent at this power rating.

¿Con qué modelos de UltraFlow Plus es compatible?

This motor is confirmed compatible with the Pentair UltraFlow Plus, WhisperFlo, and SuperFlo pump families in their 1.5 HP three-phase variants. The hydraulic end — volute, impeller, strainer pot, and clamp — remains in place; only the motor itself is swapped. Always cross-reference the nameplate on your existing motor before ordering to confirm frame dimensions and shaft specification match.

Señales de que hay que cambiarlo

A motor at end of life typically presents as one of the following: the pump hums but the shaft does not turn (stalled rotor or seized bearing), the motor runs hot to the touch and trips the thermal circuit breaker repeatedly, or it draws abnormal amperage visible on your panel instrumentation. Burnt insulation smell coming from the motor end cap is a clear indicator that the windings have failed and the motor cannot be repaired.

Cómo instalarlo

Isolate and lock out power at the distribution board before starting — three-phase circuits carry lethal voltage. Release the stainless-steel band clamp that secures the motor to the hydraulic end, slide the old motor off the shaft coupling, and fit the new unit in the reverse sequence. Reconnect the three phase conductors and earth to the terminal block, then set your magnetothermal circuit breaker precisely to the nameplate full-load amperage of this motor to protect the windings against blockage events. Check rotation direction momentarily before returning the pump to service.

Por qué es importante utilizar productos originales de Pentair

Motor units are among the most frequently cloned Pentair spare parts in the European aftermarket. Genuine Pentair motors are manufactured in Pisa, Italy, use a bi-material shaft with a stainless-steel AISI 304 drive end, and carry SKF sealed bearings — specifications that aftermarket copies routinely downgrade. A non-genuine motor fitted to a Pentair hydraulic end will void the pump warranty and may not deliver the correct shaft diameter or frame register to seal correctly against the volute.
