This is the genuine Pentair single-phase induction motor rated at 2.2 kW, supplied as an OEM replacement for the power end of UltraFlow Plus and SuperFlo pump housings. It bolts directly onto the existing hydraulic body using the stainless-steel band clamp, restoring full pump output without replacing the volute, basket housing, or plumbing unions.<\/p>\n
The motor is the drive unit that spins the impeller to generate circulation flow. At 2.2 kW on a single-phase supply, it corresponds to the top-output tier of the UltraFlow Plus range, capable of sustaining the flow rates required by large pools with demanding hydraulic resistance \u2014 elevated plant rooms, long pipe runs, or intensive vacuuming duty. Built-in thermal protection cuts power automatically if the winding temperature exceeds safe limits, protecting the motor from dry-running or blockage damage.<\/p>\n
RP301 fits the 2.2 kW (3 HP) single-phase variants of the Pentair UltraFlow Plus and SuperFlo pump families sold in the European market. The motor mates to the same square-flange mounting pattern shared across the Pentair pump range; verify your existing motor’s power rating and phase configuration against this listing before ordering. The matching three-phase motor for the same output is RP303 \u2014 confirm your site supply before purchasing.<\/p>\n
The motor requires replacement when the pump hums but the shaft does not turn (failed start capacitor or seized bearings), when it trips the thermal cut-out repeatedly under normal load, when bearing noise becomes audible during normal operation, or when the motor shows visible heat damage or water ingress around the end cap. Do not continue running a pump that trips repeatedly \u2014 overheating accelerates winding failure and risks damaging the impeller and seal plate.<\/p>\n
Motor replacement on the UltraFlow Plus and SuperFlo requires isolating the electrical supply at the distribution board, releasing the stainless-steel band clamp that joins the motor to the hydraulic body, and sliding the old motor off the shaft coupling. Electrical reconnection must be carried out by a qualified electrician in accordance with local wiring regulations and the rated supply voltage. Clean the seal plate mating face before reassembly and inspect the mechanical seal \u2014 replace it if there is any sign of wear before refitting the motor.<\/p>\n
Pump motors are one of the most commonly substituted components in the aftermarket. Genuine Pentair motors use an induction asynchronous design with an AISI 304 stainless-steel drive-end shaft and SKF sealed bearings \u2014 tolerances that non-OEM units rarely match. An undersized or incorrectly rated motor will either fail prematurely under load or fail to reach the hydraulic output the pump was designed to deliver.<\/p>","protected":false},"excerpt":{"rendered":"
