Product details

The Pentair 410016Z is the 2-1/2 inch diamond seal kit for WhisperFloXF and IntelliFloXF variable speed pumps. It is the genuine Pentair shaft seal, the same one fitted at the factory.

The leak this fixes

The shaft seal is what keeps pool water on the wet end side of the pump and off the motor. When it wears, water starts weeping from between the motor and the seal plate while the pump runs, and the drip usually shows up as a puddle under the middle of the pump rather than at a union. Left alone, that water gets into the motor bearings and turns a seal job into a motor job.

Size matters here

This is the 2-1/2 inch XF seal. It is not interchangeable with the seal used on a standard WhisperFlo, so confirm your pump is an XF model before ordering. While the wet end is open, the seal plate and diffuser o-rings are worth replacing at the same time, since both are already exposed and both are cheap next to a second teardown.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pumps take this seal?
Pentair lists 410016Z for the WhisperFloXF and the IntelliFloXF variable speed pumps.
Will it fit a standard WhisperFlo?
No. This is the 2-1/2 inch XF seal. The standard WhisperFlo uses a different shaft seal.
What does a diamond seal mean?
It refers to the hard seal face Pentair uses on the XF shaft seal, chosen for wear life against grit in the water.
How do I know the shaft seal has failed?
Water dripping from between the motor and the seal plate while the pump runs is the classic sign. It usually appears as a puddle under the middle of the pump rather than at a union.
