Product details
Speck part 2920343310 is the complete mechanical shaft seal for the 21-80 BS pool pump, in the 20 mm size.
Why complete matters
A mechanical seal works as two faces pressed together, one turning with the shaft and one held in the pump body. They wear as a pair. Fitting a new face against an old one leaves the same leak, which is why this part supplies both halves.
When to change it
Water appearing at the joint between the pump body and the motor means the shaft seal has gone. It is worth acting quickly, because the water that gets past a failed seal runs directly at the motor bearings and takes the motor with it.
