Frequently Asked Questions about Pentair IntelliFlo3 Parts

Fitment, part numbers and the assemblies shown on the IntelliFlo3 schematic.

Do the 1.5 HP and 3 HP IntelliFlo3 parts interchange?
Some do, some do not. The diffuser and union kit are horsepower-specific — 356155Z diffuser for the 1.5 HP and 356156Z for the 3 HP, with a 3" union kit (410029) on the 3 HP and a 2"/2.5" kit (410028) on the smaller pump.
Can I add a touchscreen to an IntelliFlo3 that has a blank controller?
Yes. The IntelliFlo3 VSF touchscreen add-on kit 356159Z installs in place of the blank controller cover, and the blank controller kit 356101Z is available if you want to go the other way.
What part number is the IntelliFlo3 relay board?
The pump I/O relay control board kit is Pentair 356365Z. It carries the low-voltage connections used for automation and external control signals.
Where does the IntelliFlo3 leak when the shaft seal fails?
A worn shaft seal (356210S) drips between the strainer pot and the motor, since it seals the pump shaft where it passes through the seal plate. The seal plate o-ring 356173Z is usually replaced at the same time.
