Pentair IntelliFlo VSF / IntelliFlo 2 VST Drive Kit (post-2018 / after 10-2020) — R356944 / 356944Z

Genuine Pentair replacement drive kit for the IntelliFlo VSF, IntelliFlo 2 VST, IntelliFlo VS and IntelliFlo VF variable-speed pool pumps manufactured after October 2020. This is the electronic control head that mounts on top of the motor — the module that reads keypad input, drives the variable-frequency motor and runs the schedule + speed profiles. When your pump throws a persistent drive fault or the display goes dead, this is the part you replace, not the motor block.

Csak meghajtás változat, így the keypad is sold separately (Pentair part 357527Z) — if your existing keypad is intact, keep it; otherwise order both. Compatible with the standard IntelliFlo model range including 011056 and 022056. Not compatible with the SVRS variant.

This is a big-ticket electronic assembly — before ordering, confirm the fault code on your existing drive and verify the issue can’t be resolved by a firmware reset or a keypad swap. Pentair’s IntelliFlo/IntelliPro Drive Replacement Kit Installation Guide walks through the 15-minute swap procedure in detail; you’ll want it in front of you before opening the shell. Same 4-bolt pattern to the motor and same wiring harness as the original — no adapters needed.
