Product details
The U.S. Seal PS100 is a complete mechanical shaft seal assembly, listed against Sta-Rite pool pumps including the Max-E-Glas and Dura-Glas families.
What the shaft seal does
The motor shaft has to pass out of the dry motor and into the wet end of the pump. The mechanical seal is what makes that possible: a spring loaded face turning against a fixed ceramic seat, polished flat enough to hold water back while the shaft spins. It is a wear part by design.
How you know it has failed
Water appears at the joint between the pump housing and the motor, usually as a drip that gets worse over a season. Once it starts, the water runs along the shaft toward the motor bearings, so this is not a leak to live with. Replace the seal as a matched pair, rotating face and seat together, and check the shaft and the seal plate for scoring while everything is apart.
