Product Overview

The Pentair 355024S Replacement Motor is a genuine Pentair square flange pool and spa pump motor designed for compatible Pentair pump systems. This motor features 1.5 HP performance, single-speed operation, single-phase power, and 115/208-230V electrical compatibility, depending on installation setup.

Built with a 56Y square flange frame, this motor mounts directly to compatible pump seal plates and wet ends. It is commonly referenced for select Pentair WhisperFlo, SuperFlo, and related pump applications when the motor horsepower, voltage, service factor, frame type, and impeller sizing match the existing pump setup.

Pool parts listings identify this model as a 1-speed, 1-phase, almond, 56Y square flange motor rated for 1.5 HP, 115/208-230V, and 60 Hz operation. It is also commonly listed for WhisperFlo WF-6 / WF-28 and select SuperFlo applications.

Benefits

The Pentair 355024S motor helps restore pump operation when the existing motor has failed, overheated, become noisy, or stopped running. If the pump housing, seal plate, impeller, diffuser, and plumbing are still in good condition, replacing the motor can be a cost-effective alternative to replacing the entire pump.

The 1.5 HP, single-speed, 56Y square flange design makes this motor suitable for specific Pentair pump configurations. Correct motor matching is important because horsepower, service factor, voltage, frame type, and impeller size all need to match the pump wet end.

For pool professionals, the 355024S is a practical OEM replacement motor for compatible Pentair WhisperFlo and SuperFlo service jobs.

Specifications

Included Components

• 1 × Pentair 355024S 1.5 HP square flange replacement motor

Pump housing, seal plate, impeller, diffuser, shaft seal, gaskets, O-rings, wiring, conduit, bonding wire, unions, and installation labor are sold separately unless specifically included by the supplier.

Compatibility Notes

The Pentair 355024S is designed for compatible pool and spa pump assemblies requiring a 1.5 HP, single-phase, single-speed, 56Y square flange motor.

Common compatibility references include:

• Pentair WhisperFlo pump applications
• WhisperFlo WF-6 and WF-28 references
• Select Pentair SuperFlo pump applications
• Compatible pump wet ends using a 56Y square flange motor
• Replacement applications requiring Pentair part 355024S

Always confirm the existing pump model, motor label, horsepower, service factor, voltage, frame, impeller size, seal plate style, and wiring requirements before ordering. Motor appearance alone is not enough to confirm fitment.

Installation Notes

This motor should be installed by a qualified pool professional or licensed electrician. Turn off all power at the breaker before servicing the pump.

When replacing a pump motor, inspect the shaft seal, seal plate, diffuser, impeller, gaskets, O-rings, wiring, conduit, and bonding connection. It is strongly recommended to replace the shaft seal any time the motor is replaced to help prevent water from leaking into the new motor.

After installation, verify correct voltage, bonding, grounding, motor rotation, pump priming, pressure, flow, and leak-free operation. Incorrect voltage, improper wiring, or mismatched impeller sizing can damage the motor.
