Quick overview
- Pentair part 400020Z The impeller Pentair lists for the 2 HP Whisperflo XF.
- Horsepower specific Impellers are matched to the motor rating, so a 2 HP impeller belongs on a 2 HP pump.
- Restores lost flow A worn or blocked impeller shows up as poor flow with a pump that otherwise runs normally.
- For the Whisperflo XF The XF version of the Whisperflo, which is not interchangeable with every Whisperflo part.
- Wear item Grit that gets past the basket wears the vanes over time.
- Ordered by number Use 400020Z rather than matching by eye, since impellers of different ratings look alike.

Product details
The Pentair 400020Z is the replacement impeller for the 2 HP Whisperflo XF pool pump.
What the impeller does
The impeller is the spinning part that actually moves the water. It is matched to the motor rating, which is why a 2 HP impeller goes on a 2 HP pump and not on any other. Sand and grit that slips past the strainer basket wears the vanes down over the years, and debris can pack the passages solid.
When to change it
If the pump primes, runs and sounds normal but flow is down, and you have already cleared the basket and ruled out a suction side leak, the impeller is the next thing to inspect. Order it by part number, since impellers for different ratings are hard to tell apart by eye.
