Pentair IntelliFlo Pump Parts

Which drive kit fits my Pentair IntelliFlo?

Pentair matches the drive to the pump's part number. The VS (011018, 011028), i1 (011008, 011059), i2 (011009, 011060), 2 VST (011055) and IntelliFloXF VS (022005, 022055) take 356879Z. The VS+SVRS (011017, 011057) takes 356911Z, the VSF (011056) 356922Z and the IntelliFloXF VSF (022056) 357521Z. The VSF drive changed in October 2020, so have the build date ready as well. Every model in Pentair's table takes keypad kit 357527Z.

Water is leaking from my Pentair IntelliFlo. Which part do I replace?

That depends on where it drips. Pentair's IntelliFlo3 guide traces a leak from underneath the motor to the shaft seal, a part that wears out with use; a leak at the joint between strainer pot and seal plate to a pinched or worn seal plate o-ring; and a leak at the lid to the lid o-ring. On a VS, VSF, 2 VST or VS+SVRS the shaft seal is 071734S, also found in kit 356198 and seal plate kit 350202. IntelliFlo3 seal kits come by size, and 357872 is the 3 HP one.

Which impeller fits a Pentair IntelliFlo built after October 2020?

For a VS, VSF or 2 VST built after October 2020, Pentair lists impeller 356237 and diffuser 356238. Earlier ones used the WhisperFlo's 3 HP impeller 073131 and diffuser 072928. The VS+SVRS moved to 356237 at the same date but kept diffuser 072928. The i1 and i2 are different again: Pentair gives the i1 impeller 073128 with diffuser 072930, and an i2 built after April 2016 impeller 073131A with diffuser 072927Z.

Does a Pentair IntelliFlo3 use the same parts as an older IntelliFlo?

Not in the wet end. The IntelliFlo3 has its own lid, 356172Z, with o-ring 356189Z, a different shaft seal, 356210S, and an impeller, diffuser, seal plate, strainer pot, drive and motor that differ by size. The 1.5 HP takes impeller 356176Z, diffuser 356155Z and basket 074162Z; the 3 HP takes 356177Z, 356156Z and the XF basket 400007Z. A 3 HP needs union kit 410028 for 2 or 2.5 inch pipe, or 410029 for 3 inch.

Which riser base kit does a Pentair IntelliFlo3 need to replace an older pump?

Pentair picks its three retrofit riser kits by the IntelliFlo3's size and the pump coming out. A 1.5 HP replacing an IntelliFlo or a WhisperFlo takes 357831Z, the thick C base kit. A 1.5 HP replacing an IntelliPro, Max-E-Pro or Challenger takes 357832Z, the kit with both plates. A 3 HP replacing an IntelliPro, Max-E-Pro or Challenger takes 357833Z, the thin A/B base kit.

Does a Pentair IntelliFloXF take WhisperFloXF parts?

In the wet end, yes. Pentair's IntelliFloXF lists name the WhisperFloXF wet end assembly 400000, the 3 HP impeller 400015Z with diffuser 400010, lid and locking ring 400006, basket 400007Z, the 2.5 inch union kit 410020 and seal plate 400002. The drive, keypad and motor are IntelliFlo parts, and Pentair splits the XF list at August 2015: earlier pumps list motor kit 350105S, later ones motor 350305S.
