Feel free to get in touch
The Pentair 358085 Drive Assembly is the genuine OEM 5 HP variable-speed drive, in almond finish, for WhisperFloXF VS and Max-E-ProXF VS commercial variable-speed pumps. When the drive fails but the motor and wet end are sound, this restores full variable-speed control to your high-horsepower commercial pump — far more economical than replacing the entire pump.

Frequently Asked Questions
Which pumps does the Pentair 358085 fit?
Pentair WhisperFloXF VS and Max-E-ProXF VS commercial variable-speed pumps. Confirm your pump model and horsepower on the motor label before ordering.
Is this the drive only?
Yes — it's the 5 HP drive assembly. The motor and wet end are not included. If those are still in good condition, replacing just the drive restores full function.
Why replace the drive instead of the whole pump?
On a 5 HP commercial pump, the drive is the electronic control section. If it fails but the motor and wet end are sound, replacing just the drive is dramatically cheaper than a whole new pump.
What color is it?
Almond, matching the factory WhisperFloXF / Max-E-ProXF equipment finish. A black version (358086) exists for black-finish pumps.
Does variable speed save energy on a commercial pump?
Yes — running at lower RPM for filtration significantly reduces energy use versus single-speed operation, which is why variable-speed drives are standard on modern commercial pumps.
Does it require professional installation?
Yes. This is a high-voltage, high-horsepower commercial component — installation and programming should be performed by a qualified pool professional. Disconnect power at the breaker before servicing.
