Product details

The Pentair 071725S is the shaft seal package for EQ Series and C Series pumps. It is the genuine Pentair service part.

What a shaft seal does

The motor shaft passes out of the wet end of the pump and into the motor. The shaft seal is what closes that opening, protecting the internal components from the water being pumped. It runs as two lapped faces held together, one turning with the shaft and one fixed, and it wears every hour the pump runs.

The symptom

Water dripping from between the seal plate and the motor, often with rust streaks down the motor face. Left alone it soaks the bearings and takes the motor with it, which turns a small part into a large one.

Fitting

The seal comes as a package so the faces stay matched and clean, which is what a seal needs to last. Keep the faces free of grease and grit on installation.

Questions and answers

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

Which pumps does this seal fit?
Pentair EQ Series and C Series commercial pumps.
How do I know the shaft seal has failed?
Water dripping from between the seal plate and the motor, or rust and water tracks on the motor face. A shaft seal that has given up lets pumped water run straight back along the shaft.
Why not just tighten things up?
A shaft seal is a wear part with two lapped faces. Once those faces are scored or the elastomer has hardened, no amount of tightening will stop the leak.
Should I do anything else while the pump is apart?
The lid o-ring and drain plug o-ring are cheap and reachable in the same job, and a leaking motor end is worth checking for bearing damage before reassembly.
