Product Overview

The Pentair IntelliPro VFD Motor 3.2kW PMSM, Black | 357294S is a genuine OEM replacement motor designed for select Pentair / Sta-Rite IntelliPro variable-speed pool and spa pumps.

This high-performance 3.2 kW permanent-magnet synchronous motor is engineered to operate with the compatible IntelliPro variable-frequency drive, providing the motor power required for variable-speed filtration, cleaning, spa circulation, and other programmed pool functions.

Pentair identifies 357294S as the black replacement motor used on compatible IntelliPro Variable Speed and IntelliPro VS+SVRS pump systems.

IMPORTANT

357294S is the MOTOR ONLY.

It does not include the electronic variable-speed drive, keypad, control cover, or complete pump wet end.

If the electronic drive has failed rather than the motor, a different replacement component is required.

Ideal For

• Pentair / Sta-Rite IntelliPro variable-speed pumps
• IntelliPro VS 3050 pump repair
• IntelliPro VS+SVRS pump repair
• Replacing a failed variable-speed pump motor
• Pumps with functioning drive electronics but failed motor assemblies
• Residential pool and spa circulation systems
• Professional Pentair pump service and repair

Key Features & Benefits

• Permanent-Magnet Synchronous Motor – Designed for efficient variable-speed operation.
• VFD-Compatible Motor – Operates with the IntelliPro electronic variable-speed drive.
• 230V Single-Phase Supply Application – Used with compatible IntelliPro pump systems supplied by 230V single-phase power.
• 56Y Square-Flange Configuration – Matches the physical motor mounting arrangement used on compatible pumps.
• Black OEM Finish – Correct black replacement configuration.
• Threaded Shaft Design – Designed for the applicable IntelliPro impeller assembly.
• Variable-Speed Performance – Supports the wide operating-speed range controlled by the IntelliPro VFD.
• OEM Pump Compatibility – Maintains the original motor configuration rather than adapting a generic replacement motor.

Specifications

Compatible Pump Applications

The 357294S is used with select older-generation IntelliPro variable-speed pump systems, including compatible:

• Sta-Rite IntelliPro VS 3050
• Pentair / Sta-Rite IntelliPro Variable Speed
• IntelliPro VS+SVRS

Pentair also lists 357294S in its replacement-parts information for IntelliPro variable-speed pumps manufactured before the newer IntelliPro pump generations.

Because IntelliPro pumps have gone through several design revisions, verify your existing pump model and motor part number before ordering.

Motor Only – Drive Not Included

This distinction is extremely important.

IntelliPro Variable Speed Drive Kit

The electronic drive mounts to and controls the motor but is a separate replacement component.

If your pump:

• Has a blank display
• Shows drive faults
• Will not accept commands
• Has damaged drive electronics

the problem may be with the drive rather than the motor.

If the motor:

• Has failed bearings
• Will not rotate
• Is electrically damaged
• Is making excessive mechanical noise

then the 357294S motor may be the appropriate replacement.

Proper diagnosis before ordering can prevent replacing the wrong component.

IntelliPro Variable-Speed Technology

The motor works together with the IntelliPro electronic drive.

Instead of operating at only one fixed motor speed, the VFD controls motor operation based on programmed RPM.

This allows the pump to operate at:

• Lower speeds for everyday filtration
• Medium speeds for heating or circulation
• Higher speeds for cleaning
• Higher speeds for spa operation
• Programmed speeds for water features and other pool functions

Lower pump speeds can significantly reduce electrical demand compared with operating a traditional single-speed pump continuously at full speed.

Permanent-Magnet Motor Design

The 357294S uses permanent-magnet synchronous motor technology rather than a conventional induction-motor design.

This motor architecture is specifically matched to the IntelliPro electronic variable-speed drive and should not be treated as a standard standalone pool-pump motor.

The compatible IntelliPro VFD is responsible for controlling motor speed and operation.

Important Compatibility Notice

DO NOT ORDER BY HORSEPOWER ALONE

This is not a universal 4.3 HP replacement motor.

Before ordering, confirm:

• Existing pump model
• Existing motor part number
• Pump manufacturing generation
• Voltage
• Motor frame
• Drive compatibility
• Whether the failure is actually the motor or electronic drive

Newer IntelliPro and IntelliPro VSF/VST pump generations may use different motor and drive assemblies.

Replace the Shaft Seal During Motor Service

Whenever a pool-pump motor is removed from the wet end, replacing the mechanical shaft seal is strongly recommended.

An old or damaged mechanical seal may leak pool water onto the new motor shaft and bearings, potentially causing premature motor failure.

Technicians should also inspect:

• Shaft seal
• Seal plate
• Impeller
• Diffuser
• O-rings
• Drive gasket
• Motor hardware
• Pump housing

Replace worn or damaged components during reassembly.

Installation Guidance

Installation should be performed by a qualified pool technician or electrician familiar with Pentair variable-speed pumps.

Before service:

• Disconnect power at the breaker
• Verify voltage is off
• Confirm the correct replacement motor
• Inspect the existing drive
• Replace the mechanical seal
• Inspect the wet end for leaks or damage

After installation, verify:

• Correct drive communication
• Motor rotation
• Programmed speeds
• Pump priming
• Water flow
• Electrical operation
• No shaft-seal leakage

Frequently Asked Questions

What pumps does Pentair 357294S fit?
It is used with compatible older-generation Pentair / Sta-Rite IntelliPro variable-speed pumps, including IntelliPro VS 3050 and IntelliPro VS+SVRS applications.

Is 357294S the motor and drive together?
No. 357294S is the motor only.

What is the separate IntelliPro drive?
For applicable IntelliPro variable-speed systems, Pentair lists 353252 as the separate Variable Speed Drive Kit.

What is the power rating?
3.2 kW, approximately equivalent to a 4.3 HP motor rating.

What voltage is the motor used with?
Compatible systems operate from 230V single-phase power.

What motor frame is it?
56Y square flange.

Is it a standard replacement pool motor?
No. It is a specialized permanent-magnet motor designed to operate with the compatible IntelliPro variable-speed drive.

Should I replace the shaft seal?
Yes. Replacing the mechanical shaft seal whenever the motor is removed is strongly recommended.

Does it include the impeller?
No. The impeller and pump wet-end components are separate.

Why Buy From Pool Supply Depot?

Pool Supply Depot supplies genuine Pentair and Sta-Rite variable-speed pumps, replacement motors, drives, seal kits, impellers, pump wet-end components, filters, heaters, automation systems, and OEM replacement parts nationwide.

Because IntelliPro pumps have multiple generations and the motor and electronic drive are separate service components, we recommend verifying the existing pump model and motor label before ordering.
