Product Overview

Restore your compatible Pentair variable-speed pool pump with the Pentair VST Drive and Motor with Keypad | 356289S. This genuine Pentair replacement assembly combines the variable-speed motor, electronic drive, and integrated control keypad into one complete replacement unit.

The 356289S is designed for compatible Pentair SuperFlo® VST, SuperFlo VS, and WhisperFlo® VST variable-speed pool pumps. It is an excellent solution when the existing motor or electronic drive has failed but the pump wet end, housing, impeller, and plumbing remain in usable condition.

Featuring a high-efficiency permanent-magnet motor, Totally Enclosed Fan Cooled construction, variable-speed operation, and RS-485 automation capability, the 356289S restores the advanced performance and programming functions expected from a Pentair VST pump.

Warranty & Compatibility

Pump Compatibility

The Pentair 356289S is used with compatible models in the following pump families:

• Pentair SuperFlo VST
• Pentair SuperFlo VS
• Pentair WhisperFlo VST
• Certain compatible SuperMax VS configurations

For SuperFlo VS/VST applications, Pentair lists this motor/drive assembly with the post-October 2020 pump generation.

Because Pentair has produced multiple generations and revisions of these pumps, customers should verify the exact pump model, manufacturing date, motor color, and existing part number before ordering.

Important Horsepower Information

The 356289S motor/drive assembly can be used on pump platforms with different hydraulic ratings.

For example, compatible SuperFlo VST configurations may be rated around 2.2 THP, while WhisperFlo VST configurations may be rated differently depending on the pump wet end.

The final pump performance depends on the wet end, impeller, diffuser, voltage, and pump configuration. For this reason, the 356289S should be selected by compatible pump model and replacement part number rather than horsepower alone.

Customer-Facing Q&A

Q: Is 356289S only the drive?
A: No. The 356289S is the complete motor and drive assembly, not simply the electronic drive board.

Q: Does the keypad come with it?
A: Yes. The motor/drive assembly includes the integrated control keypad.

Q: Does it fit the Pentair SuperFlo VST?
A: Yes, it is listed for compatible SuperFlo VS/VST pumps, particularly the generation manufactured after October 2020.

Q: Does it fit the WhisperFlo VST?
A: Yes. Pentair also lists 356289S as a compatible motor/drive assembly for WhisperFlo VST applications.

Q: What voltage does it require?
A: The compatible motor/drive platform accepts approximately 115–230V, single-phase, 50/60 Hz power.

Q: Does it support pool automation?
A: Yes. The 356289S has RS-485 communication capability. Additional wiring or automation components may be required.

Q: Do I need to replace the shaft seal?
A: A new shaft seal is strongly recommended whenever the motor is separated from the pump wet end. The correct seal should be selected based on the exact pump model.

Q: Is this a complete pool pump?
A: No. 356289S is the motor, drive, and keypad assembly only. It does not include the complete pump wet end.
