Pentair - Motor pentru pompă UltraFlow Plus, trifazat, 0,55 kW - RP073

Pentair UltraFlow Plus pump motor 0.55 kW three-phase

This is the genuine Pentair OEM replacement motor unit rated at 0.55 kW (¾ CV) for three-phase electrical supplies, designed to bolt directly onto the wet end of the UltraFlow Plus and its sibling pump families. When your existing motor seizes, burns out, or develops bearing noise, this part restores full circulation without replacing the entire pump assembly.

Ce face acest motor în cadrul sistemului UltraFlow Plus

The motor drives the impeller shaft, converting three-phase electrical input into the rotational force that moves water through the pump volute. Because it is an induction asynchronous motor manufactured to Pentair’s own specification, it delivers the torque curve and operating temperature the UltraFlow Plus wet end was engineered around — not an approximation from a generic replacement.

Cu ce modele UltraFlow Plus este compatibil

RP073 fits the three-phase variants of the UltraFlow Plus, WhisperFlo, and SuperFlo pump families sold in Europe. It also crosses to the WhisperPro, Challenger, and the La Sta-Rite HD and HD-SW ranges (references P-STRHD-073 and P-STR-073). Always cross-check the exploded-view diagram for your exact pump model before ordering — the 0.55 kW three-phase rating must match your existing nameplate. The single-phase equivalent at this power rating is RP071.

Semne care indică faptul că trebuie înlocuit

The motor needs attention when the pump hums but fails to start (capacitor or winding failure), runs hot and trips its thermal overload, produces grinding or rumbling from worn bearings, or draws noticeably higher current than its rated value. Shaft seal leakage that has allowed water ingress into the motor end-shield is also a common cause of winding failure at this power rating.

De ce este important să alegi produse originale Pentair

Motor units are among the most commonly cloned pool pump components. Aftermarket motors frequently use undersized windings or inferior bearing grades that cause premature failure and void the pump warranty. The genuine RP073 is manufactured at Pentair’s Pisa, Italy plant to the same specification as the original — including a bi-material shaft with a stainless steel AISI 304 drive end and SKF sealed bearings — ensuring correct mechanical fit and long service life.
