Product details

The Pentair 071734S is the shaft seal kit for WhisperFlo WFE and IntelliFlo pool pumps. It is the genuine Pentair part, and Pentair notes it may fit other pump models as well.

What the shaft seal does

The seal rides on the motor shaft behind the impeller and keeps pool water on the wet end where it belongs. When it wears, water tracks along the shaft and drips out between the pump housing and the motor. Left alone, that water finds the motor bearings and turns a small part into a large one.

Fitting it

The seal sits behind the impeller, so the wet end has to be opened and the impeller removed. Since the pump is already apart, most people replace the housing and lid o-rings at the same time.

Make it last

Shaft seals do not survive dry running. If the pump has been losing prime or pulling air on the suction side, sort that out before fitting the new seal.

Questions and answers

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

Which pumps does this seal kit fit?
It is listed for Pentair WhisperFlo WFE and IntelliFlo model pumps, and Pentair notes it may fit other models as well.
Is it a genuine Pentair part?
Yes. It is the Pentair OEM seal kit, part number 071734S.
How do I know the shaft seal has failed?
Water shows up under the pump between the wet end and the motor, and it keeps coming while the pump runs. That leak path is the shaft seal, not the housing o-ring.
What else should I replace at the same time?
The housing and lid o-rings. They are cheap, they harden with the seal, and the pump is already apart to reach the seal.
