Product Overview

The Pentair WhisperFloXF 354819S is a genuine OEM 5 HP replacement pump motor designed for compatible Pentair WhisperFloXF high-performance pool pumps. Built with a Totally Enclosed Fan-Cooled (TEFC) enclosure, this single-phase motor operates on 208-230V power and is engineered for demanding pool circulation applications.

It is specifically identified by Pentair for the WhisperFloXF XFET-20 pump configuration, making it an excellent choice when the existing pump wet end remains serviceable but the original motor requires replacement.

Ideal For

• Pentair WhisperFloXF XFET-20 pump motor replacement

• Commercial and high-demand residential pool systems

• Repairs where the pump housing and hydraulic components remain in usable condition

• Applications requiring a 5 HP, 208-230V single-phase TEFC motor

Key Features

• Genuine Pentair OEM replacement motor

• 5 HP motor rating for high-flow WhisperFloXF applications

• Single-phase electrical configuration

• Designed for 208-230V operation

• Totally Enclosed Fan-Cooled construction helps isolate internal motor components from outside contaminants

• Heavy-duty design intended for demanding pool-equipment environments

• Compatible with the Pentair WhisperFloXF XFET-20 configuration

• 56-frame square-flange motor configuration

Benefits

Replacing only the motor can restore a compatible WhisperFloXF pump without requiring replacement of the complete pump assembly when the existing wet end is still in good condition.

The TEFC construction is particularly beneficial in pool equipment environments because outside air is not continuously pulled through the motor's internal components as it is with an open-style motor. This design helps protect the internal motor assembly from airborne moisture, dust, and contaminants.

Using the genuine Pentair replacement motor also helps maintain the proper motor configuration for the original WhisperFloXF hydraulic assembly.

Compatibility

Pentair identifies the 354819S motor for the WhisperFloXF XFET-20 pump.

A common complete pump configuration using this motor is:

• WhisperFloXF XFET-20

• 5 HP

• 208-230V

• Single phase

• TEFC motor configuration

Pentair pairs this motor with the 400634Z WhisperFloXF XFET-20 power-end assembly.

Do not select a replacement motor based only on horsepower. Verify the existing pump model, voltage, phase, motor type, and Pentair part number before ordering.

Installation & Replacement Context

The 354819S is the motor component only. It is not a complete WhisperFloXF pump and does not include the pump housing, strainer assembly, diffuser, impeller, or complete power-end assembly unless specifically stated otherwise.

Because this is a high-horsepower electrical component, installation and electrical connection should be performed by a qualified pool or electrical professional. Existing seals and related service components should be inspected during motor replacement.

What's Included

• Pentair 354819S replacement motor

• 5 HP single-phase TEFC motor assembly

Pump housing, impeller, diffuser, mechanical seal, gaskets, wiring, and additional replacement components are not included unless specifically packaged with the motor.

Confirm Before Ordering

Verify:

• Existing pump is a compatible WhisperFloXF configuration

• Existing motor or replacement requirement matches 354819S

• 208-230V electrical supply

• Single-phase power

• 5 HP motor requirement

• TEFC motor configuration

Specifications

Customer Q&A

Is 354819S a complete pool pump?

No. This is the replacement motor only. The WhisperFloXF pump housing, hydraulic components, and other service parts are separate.

Which WhisperFloXF pump uses this motor?

Pentair identifies 354819S as the 5 HP single-phase TEFC motor for the WhisperFloXF XFET-20 configuration.

Will this replace a three-phase 5 HP WhisperFloXF motor?

No. The 354819S is specifically a single-phase 208-230V motor. Pentair uses different part numbers for three-phase configurations.

Can I replace only the motor instead of the entire pump?

Yes, when the existing WhisperFloXF wet end and hydraulic components are still serviceable and the system is confirmed compatible. Inspect the pump's seal, impeller, diffuser, and other wear components during the repair.

Warranty

Pentair warranty coverage can depend on the product, installation method, sales channel, and current manufacturer warranty terms. Confirm applicable warranty requirements for this replacement motor before installation.
