Product Overview

The Pentair 356944Z IntelliFlo VSF Drive is a genuine OEM replacement variable-speed and flow drive designed for compatible Pentair IntelliFlo VSF pool pumps manufactured after October 2020. The drive controls motor speed, programmed flow rates, priming functions, schedules, and communication with compatible Pentair automation systems.

This replacement is intended for pumps with a functioning motor and reusable keypad but a failed or damaged electronic drive. Common symptoms of drive failure may include a blank or unresponsive display, communication errors, failure to start, intermittent operation, loss of speed control, or electrical fault messages.

This listing includes the electronic drive only. The keypad, motor, pump wet end, communication cable, and complete pump assembly are not included. The existing compatible keypad can be transferred to the replacement drive, or keypad assembly 357527Z can be purchased separately.

Warranty & Compatibility

Compatible Applications

The 356944Z is designed for compatible Pentair IntelliFlo VSF pumps manufactured after October 2020. Compatibility must be confirmed using the pump model number, serial number, manufacturing date, and original drive part number.

This drive should not be assumed compatible with older IntelliFlo VSF pumps, standard IntelliFlo VS models, IntelliFlo2 VST models, SVRS pumps, or IntelliFlo3 pumps. Different pump generations and manufacturing dates may use different drive assemblies.

Installation Information

Installation should be performed by a qualified pool professional or licensed electrician familiar with variable-speed pool pumps. Disconnect all electrical power at the circuit breaker before servicing the pump.

The existing keypad may need to be transferred to the new drive. Inspect the keypad, communication connections, motor wiring, bonding, power supply, and pump motor before installation. After replacement, reconnect the pump to any existing automation system and re-enter operating schedules if required.

Never apply power until all wiring, grounding, bonding, and enclosure seals have been properly installed.

• Your existing motor is operational
